Important Notice − Please Read
The manuals supplied with your Waterous equipment contain:
w
Warranty Information
Warranty information contains the Conditional Warranty for Waterous Pumps.
•
Instructions
Instructions contain information on the operation, maintenance, and overhaul of your Waterous fire pump, transmission or power take−off.
•
‘‘Computer Printout’’ Service Parts Lists
‘‘Computer printout’’ service parts lists show your order, serial, assembly, and part numbers,
along with the model name and part descriptions.
•
‘‘Printed’’ Service Parts Lists
“Printed” service parts lists show exploded diagrams of a particular assembly along with part
descriptions.
These manuals pertain to the complete unit as it was shipped from Waterous. Changes made by others after shipment
may affect the applicability of the information in these manuals. Contact the apparatus manufacturer or Waterous
Company if you have questions.
The manual is divided into sections according to the major components plus accessories and options supplied with
the unit. Each section contains operation, maintenance and overhaul instructions, where applicable, plus parts illustrations and accompanying computer generated parts lists. The parts lists give the piece part numbers for all of the
piece parts used, plus the description and quantity used. The reference number, where applicable, appearing on the
parts list corresponds to the reference number on the illustration.
To find a given part number for ordering, refer to the appropriate service parts list illustration to find the part needed.
Note the reference number shown on the illustration for the part, and find that reference number in the reference number column of the computer generated list and note the complete part number for the part needed, including all letters,
numbers and dashes, as shown in the part number column.
Ordering Parts
1. Check the serial numbers listed at the top of the computer generated service parts list against the numbers on
the serial plates on the components for which the repairs are needed.
2. Check to make sure you have found the correct and complete number for all parts needed for repair.
3. Furnish all applicable serial numbers and part numbers when placing the order for repair parts.
NOTE: If parts are ordered by part number only and appropriate serial numbers are not furnished, Waterous cannot be held responsible for delays caused by incorrect parts orders.

The two main parts of centrifugal pumps are the impeller(s) and volute(s). The
impeller is powered to rotate within the volute, creating centrifugal force which
hurls the water from the impeller eye outward through the impeller. The volute
is a spiral shaped flow passage surrounding the impeller, which collects the water
from the impeller and guides it to pump discharge. In operation, atmospheric or
other pressure continuously forces water through pump intake passages into the
eye and the rotating impeller forces it outward into the volute and to the pump discharge. Figure 1 shows the path a single drop of water takes through a centrifugal
pump. Pump discharge pressure and capacity can be regulated by adjusting
pump speed, transfer valve setting, discharge valve opening and nozzle size.

Signs of Cavitation
Multi−Stage Pumps
When variations in capacity and pressure are required beyond that which can
conveniently be obtained from a single impeller, then multi−stage series/parallel
pumps are used. These pumps have two or more impellers, each enclosed in
its own volute,which is usually part of a common body. A transfer valve at the outlet of the first stage volute directs the water either to pump discharge or to second
stage intake, depending on how the pump is being used.
1. Sudden pressure or capacity loss.
When the transfer valve is in VOLUME (parallel) position, the water enters each
impeller eye from a common intake and leaves through a common pump discharge. See figure 2. If the transfer valve is turned to PRESSURE (series) position, the first stage pumps its full volume and pressure directly to the second stage
intake, instead of to pump discharge. The second stage then pumps this same
volume of water to pump discharge, but at twice first stage pressure. With the
transfer valve in this position, first stage pressure also closes the flap valves in
the intake passageways which prevents water from bypassing back to first stage
intake. See figure 3.
Reducing pump speed or improving intake conditions will usually eliminate cavitation.
Cavitation
2. Increasing pump speed without corresponding increase in volume or pressure.
3. Excessive pump vibration.
4. A rattling sound resembling gravel going through the pump.
Overheating
Any liquid, at any temperature, forms a vapor over its surface which produces a
certain amount of pressure. This ‘‘vapor pressure” increases as the liquid temperature rises. When the vapor pressure is equal to or greater than the pressure surrounding the liquid, the liquid boils. Vapor pressure is important because of the
way it affects pump operation.
5
Page 5
If the pump runs even for a few minutes completely closed it may heat the water
enough to scald someone when the valve is opened. When operating the pump,
at least one discharge valve should be open slightly to prevent the pump from
overheating. Overheating can damage the packing, seals and other pump parts.
If the apparatus builder has installed a bypass system or other provision designed
to prevent overheating, opening a discharge valve may be unnecessary.
Each pump is designed to operate within a given speed range, and under a specific set of intake conditions. Operating a pump at excessive speed, too high an intake lift, restricting the intake, or any other factor that causes the pressure on the
liquid to fall below its vapor pressure produces a condition called ‘‘cavitation”.
When this condition exists, the liquid vapor released in the low pressure regions
of the pump forms bubbles. These bubbles are carried into the high pressure sections of the impeller (underneath each vane) where they collapse with considerable force. This may cause pitting near the impeller vane tips.

Inspection Tests
A regular testing program offers the best means of determining the actual condition of a pump and its accessories, and permits locating problems before they
cause trouble. At a fire, it is usually difficult for the pump operator to observe the
pump closely enough to determine its true condition.
Conduct these tests either every month or annually, as outlined below:
Monthly Tests
I. Vacuum Test
Mechanical Seals − Mechanical seals should not leak. Refer to MAINTENANCE INSTRUCTIONS for the particular pump involved for mechanical
seal maintenance.
3. Transfer Valve (series/parallel pumps only) − With the pump running at idle
speed, switch valve from one position to the other several times to make sure
it operates properly. If the transfer valve is equipped with a grease fitting, lubricate it in accordance with MAINTENANCE INSTRUCTIONS for the pump involved.
4. Shift − Check shift mechanism to make sure it is working properly.
Remove all caps except openings without valves. Close all discharge, intake,
drain valves and other similar openings. Operate priming device to create a vacuum of about 22 in. Hg/.735 atmospheres in pump, then stop primer and engine.
5. Performance − Check pump speed at rated pressure and capacity.
Watch pressure gage; if vacuum drops more than 10 in. Hg/.334 atmospheres in
5 minutes, listen for air leaks around packing glands, gaskets, valves, etc.
6. Accessories − Operate all discharge and intake valves, relief valve, drain
valve and similar accessories to make sure that they all function correctly. If
any power accessories are installed, be sure to operate the overrides (if connected) to make sure they operate properly.
Replace gaskets, repack or otherwise repair source of trouble.
7. Indicating Lights − Check to make sure they are working properly.
II. Pressure Test (Hydrostatic)
Annual Tests
III. Running Test
Run pump for at least 15 minutes from draft, if possible. Drafting is best because
the pump is then more sensitive to defects than when connected to a pressurized
water source. Check the following:
1. Priming Ability − If pump does not prime readily (30 seconds for 1250 GPM
(4731 L/min) or less and 45 seconds for 1500 to 2000 GPM (5678 to 7570
L/min) pumps) stop pump and determine cause. (An additional 15 seconds
may be required if the pump is equipped with a 4 inch or larger front or rear
intake.)
2. Shaft Seal
Packing − Packing should leak a small amount to keep it cool and lubricated.
Refer to MAINTENANCE INSTRUCTIONS for the particular pump involved
for specific leakage rate and packing adjustment.
1. At least once a year, test the pumper to determine if it is capable of meeting the requirements outlined in NFPA 1911, Tests of Pumps on F.D. Apparatus. Compare the pump and engine speeds observed in these tests with
those in the acceptance and other previous tests. If the speeds observed
in the latest tests are much higher, the pump probably requires some
repairs.

Page 8
Connect pump to a hydrant or other pressurized water source. Remove all caps
except openings without valves. Close all discharge, intake, drain valves and
other similar openings. Turn on inlet valve and ‘‘crack” highest discharge valve
on pump to expel air from pump. Close discharge valve. Carefully examine pump
and accessories for leaks. Replace gaskets, tighten joints, repair valves or repack
as necessary to eliminate leaks. (See ‘‘Packing” under running tests below.)
2. Tank to Pump Check Valve − Remove the tank to pump valve and associated piping and inspect check valve for excessive wear and replace if necessary.
!
WARNING
Equipment Hazard. May cause severe injury to hands or arms.
Make sure all equipment is turned off prior to reaching into the intake fitting
to inspect the intake adapter flap valve.
3. Intake Adapter Flap Valves (Side Intakes only) − Reach inside intake fitting
and check the movement of the flap valve. Flap valves should sit securely
in the machined slots of the fitting and open and close smoothly.

Troubleshooting
CONDITION
POSSIBLE CAUSE
SUGGESTED REMEDY
Clean and tighten all intake connections. Make sure intake hoses and gaskets are in good condition.
Use the following procedure to locate air leaks:
1.
Connect intake hose to pump and attach intake cap to end of hose.
2.
Close all pump openings.
3.
Operate primer until vacuum gage indicates 22 in. Hg/.735 atmospheres. (If primer fails to draw specified vacuum, it may be defective, or leaks are too large
for primer to handle.)
4.
Shut off primer. If vacuum drops more than 10 in. Hg/.334 atmospheres in 5 minutes, serious air leaks are indicated. With engine stopped, air leaks are frequently
audible. If leaks cannot be heard, apply engine oil to suspected points and watch for break in film or oil being drawn into pump.
Air leaks
Completely fill water tank (if so equipped). Connect intake hose to hydrant or auxiliary pump. Open one discharge valve and run in water until pump is completely
filled and all air is expelled. Close discharge valve, apply pressure to system and watch for leaks or overflowing water tank. A pressure of 100 psi is sufficient. DO
NOT EXCEED RECOMMENDED PRESSURE.
If pump has not been operated for several weeks, packing may be dried out. Close discharge and drain valves and cap intake openings. Operate primer to build up
a strong vacuum in pump. Run pump slowly and apply oil to impeller shaft near packing gland. Make sure packing is adjusted properly.
Remove all leaves, dirt and other foreign material from intake strainer.
When drafting from shallow water source with mud, sand or gravel bottom, protect intake strainer in one of the following ways:
Dirt on intake strainer
Pump fails to prime or
loses prime
A. Engine and pump
speed too low at full
throttle
Suspend intake strainer from a log or other floating object to keep it off the bottom. Anchor float to prevent it from drifting into shallow water.
2.
Remove top from a clean barrel. Sink barrel so open end is below water surface. Place intake strainer inside barrel.
3.
Make an intake box, using fine mesh screen. Suspend intake strainer inside box.
No lubricant in priming tank
With some rotary primers, lubricant is required to maintain a tight rotor seal. Check priming tank oil supply and replenish, if necessary.
Lubricant tubing/check valve
If there is lubricant in the tank, but lubricant does not enter (exit) the primer, the check valve may be stuck (replace) or installed backwards (arrow points towards
primer) or the tubing may be clogged, especially if using a biodegradable lubricant and primer is not operated on a regular basis. Clear clog or replace tubing per
Priming System Installation Instructions.
Defective priming valve
A worn or damaged priming valve may leak and cause pump to lose prime. Consult primer instructions for priming valve repair.
Improper clearance in rotary gear or
vane primer
After prolonged service, wear may increase primer clearance and reduce efficiency. Refer to primer instructions for adjusting primer clearance.
Engine speed too low
Refer to instructions supplied with primer for correct priming speeds. Speeds much higher than those recommended do not accelerate priming, and may actually
damage priming pump.
Bypass line open
If a bypass line is installed between the pump discharge and water tank to prevent pump from overheating with all discharge valves closed, look for a check valve
in the line. If valve is stuck open, clean it, replace it or temporarily block off line until a new valve can be obtained.
Lift too high
Do not attempt lifts exceeding 22 feet (6.7m)except at low altitudes and with equipment in new condition.
End of intake hose not submerged
deep enough
Although intake hose might be immersed enough for priming, pumping large volumes of water may produce whirlpools, which will allow air to be drawn into intake
hose. Whenever possible, place end of intake hose at least two feet below water source.
High point in intake line
If possible, avoid placing any part of intake hose higher than pump inlet. If high point cannot be prevented, close discharge valve as soon as pressure drops, and
prime again. This procedure will usually eliminate air pockets in intake line, but it may have to be repeated several times.
Primer not operated long enough
Refer to operation instructions supplied with primer for required priming time.

Insufficient capacity
1.
Engine requires maintenance. Check engine in accordance with manufacturer’s instructions supplied with truck.
Insufficient engine power
Discharge relief valve set improperly
Engine operated at high altitudes and/or high air temperatures. Engine power decreases with an increase in altitude or air temperature, except for turbo charged
engines. Adjusting carburetor or changing carburetor jets (or injector nozzles) may improve engine performance. Consult with engine manufacturer.
If relief valve is set to relieve below desired operating pressure, water will bypass and reduce capacity. Adjust relief valve in accordance with instructions supplied
with valve.

CONDITION
A. Engine and pump
speed too low at full
throttle
(continued)
B. Engine and pump
speed higher than specified for desired pressure and volume
POSSIBLE CAUSE
Transfer valve set improperly
(Does not apply to single stage
pumps.)
Truck transmission in too high a gear
SUGGESTED REMEDY
Place transfer valve in VOLUME (parallel) position when pumping more than two thirds rated capacity.
When shifting transfer valve, make sure it travels all the way into new position. Failure of transfer valve to move completely into new position will seriously impair
pump efficiency.
Consult vehicle instructions for correct pump gear. Pump usually works best with transmission in direct drive. If truck is equipped with an automatic transmission,
be sure transmission is in pumping gear.
Transfer valve set improperly
(Does not apply to single stage
pumps.)
Place transfer valve in VOLUME (parallel) position when pumping more than two thirds rated capacity.
Pump impeller(s) or wear rings badly
worn
Install undersize wear rings if impeller to wear ring clearance is within limits indicated in MAINTENANCE INSTRUCTIONS. If not, install new impeller(s) and wear
rings.
Intake strainer, intake screens or
impeller vanes fouled with debris
Remove intake strainer and hose, and clear away all debris. Pressure backwash (preferably in parallel or ‘‘volume’’ position) will usually clear impeller vanes
when pump is stopped.
Intake hose defective
On old intake hoses, the inner liner sometimes becomes so rough it causes enough friction loss to prevent pump from drawing capacity. Sometimes, the liner will
separate from the outer wall and collapse when drafting. It is usually impossible to detect liner collapse, even with a light. Try drafting with a new intake hose; if
pump then delivers capacity, it may be assumed that previous hose was defective.
Intake hose too small
When pumping at higher than normal lifts, or at high altitudes, use a larger or additional intake hoses.
Truck transmission in too low a gear
Consult vehicle instructions for correct pumping gear. Pump usually works best with transmission in direct drive. (Check both engine and pump speed, if possible, to be sure transmission is in ‘‘direct’’.)
When shifting transfer valve, make sure it travels all the way into new position. Failure of transfer valve to move completely into new position will seriously impair
pump efficiency.
C. Engine speed higher
than specified for
desired pressure and
volume
Insufficient pressure
Relief Valve Malfunction
A. Pressure not relieved
when discharge valves
are closed
B. Pressure will not return
to original setting after
discharge valves are
reopened
D. Slow response
Check pump speed with a tachometer. If pump speed is too low, refer to engine manufacturer’s instructions for method of adjusting engine speed governor.
Pump capacity limits pump pressure
Do not attempt to pump greater volume of water at the desired pressure than the pump is designed to handle. Exceeding pump capacity may cause a reduction
in pressure. Exceeding maximum recommended pump speed will produce cavitation, and will seriously impair pump efficiency.
Flap valve stuck open
When pump is in PRESSURE (series), discharge will bypass to first stage intake. Operate pump at 75 psi/5.2 bar, and rapidly switch transfer valve back and
forth between positions. If this fails, try to reach valve with a stick or wire and work it free.
Sticky pilot valve
Disassemble and clean. Replace noticeably worn parts.
Plugged tube lines
Disconnect lines and inspect.
Sticky pilot valve
Sticky main valve
Incorrect installation
Check all lines to be sure installation instructions have been followed.
Sticky pilot valve
Water surges
(relief valve)
Pressure fluctuation can result from a combination of intake and discharge conditions involving the pump, relief valve and engine. When the elasticity of the
intake and discharge system and the response rate (reaction time) of the engine, pilot valve and relief valve are such that the system never stabilizes, fluctuation
results. With the proper combination of circumstances, fluctuation can occur regardless of the make or type of equipment involved. Changing one or more of
these factors enough to disrupt this timing should eliminate fluctuation.
Plugged filter or line
Clean lines and filter.
C. Fluctuating pressure
In general, the above causes and remedies for low pump capacity will also apply to low pump pressure.

Introduction
This instruction contains the information needed for operation and maintenance of CS Series centrifugal pumps. Since there
are several types of transmissions available for these pumps, they are covered in separate instructions.
General Description
The CS Series pumps are single stage centrifugal fire
pumps. They are designed for midship mounting and are
available in capacities ranging from 750 to 2250 gpm
(2850 to 8500 l/m).
A variation of the basic pump is the CSH pump. This two
stage pump has an extra pressure stage designed for
high pressure operation. It is identical to the CS except for
the added stage and piping.
Components
Body Assembly
Impeller Shaft Assembly
This assembly includes the body, cover, intake adapters
and related parts. The body, cover and adapters are either
cast iron or bronze.
This assembly consists of the bronze impeller mounted on
a stainless steel shaft with wear rings, packing or mechanical seal and related parts. The impeller is balanced
and the impeller shaft is supported by ball bearings.
Options
Mechanical Seals
Extra Pressure Stage
A mechanical seal consists of a flat, highly polished
(lapped), spring−fed carbon ring that is sealed to and rotates with the impeller shaft. It presses against a highly
polished (lapped), silicone carbide, stationary ring that is
sealed in the pump body. This seals the shaft and prevents air from entering and water from leaving. A mechanical seal does not leak or drip water, even when pumping.
The extra pressure stage provides extra pressure without
the need of a separate PTO driven pump. When the extra
pressure stage control valve is opened, water enters the
extra pressure stage intake from the main pump discharge, and is discharged at a higher pressure. With the
extra pressure stage in operation, the CSH pump develops pressure up to 500 psi (1900 l/m) for two or more
booster lines. The extra pressure body mounts on the
main body opposite the pump drive end. The impeller is
mounted on the same shaft as the other impeller and rotates whenever the pump is in operation. When the extra
pressure stage is not in use, water from the first stage lubricates and cools the extra pressure stage stuffing box.
Flame−Plated Impellers
Approximately 75% of the pump wear due to pumping
sand, occurs on the impeller hubs. For this reason, the
Waterous Company adopted the policy of offering a flame
plated impeller as an option (standard on CSU pumps).
The flame−plating process consists of adding tungsten
carbide to the surfaces to be protected from wear. This
unique process produces extremely hard, well bonded,
wear−resistant coatings which consistently outwear hard
chrome plating, tool steel and solid tungsten carbide.
Monarch Intake Valve
The Monarch intake valve is a package including an extra
short intake fitting, an intake butterfly valve and an intake
nipple with integral relief valve mounting pad, all designed
to fit behind the pump panel. The Monarch intake valve
also features a provision for a pre−valve relief valve and
choice of manual worm gear, pneumatic or 12 or 24 volt
electric actuator. For operation and maintenance instructions for the Monarch intake valve, see the following instructions:
•
F−1031, Section 2318, Operation, Maintenance and
Installation Instructions for Butterfly Valves
Intake Screens
Zinc die cast screens are normally used in the intake fittings, with brass screens available optionally. Although the
screens are chemically treated (coated) to inhibit corrosion, the water being pumped may still corrode the
screens. Such corrosion is ‘‘sacrificial”; that is, it will help
prevent corrosion in the rest of the pump the same way
the magnesium anodes protect the metal parts of a water
heater.
Anodes
As additional corrosion protection for iron body pumps,
Waterous has available zinc anodes to fit any unused
intake pad, 2−1/2 inch or 3 inch pipe tap in the intake fittings. Anodes provide additional zinc surface to the water
to supplement the zinc intake screens.

Tank to Pump Valve
Overheat Protection Manager (OPM)
The tank to pump valve is a full−flow 3−1/2 inch diameter
ball valve which is attached directly to the pump.
The Overheat Protection Manager (OPM) acts as a safety
device by releasing hot water to the ground or back to the
water tank from the discharge area of the pump.

Maintenance
Corrosion Protection
Figure 6. Bolt−on Anodes
Optional Zinc Intake Screens
Once per month check to make sure the intake screens
are not clogged or damaged. Also check for corrosion, and
replace screens if damage is severe. For the zinc screen
to adequately control corrosion, there must be a strong
electrical contact between the screen and the fitting.
Remove any corrosion, debris or paint from the counter
bore that will insulate the screen from the intake fitting. If
the screen does not fit tightly, adjust the gap of the slot on
the outside diameter of the screen to ensure a tight fit.
NOTE: These screens are die−cast which results in a
slight taper from one side to the other. Install the
screen with the thinner cross−section facing out to
minimize flow restriction.
Figure 5. Zinc Intake Screens
Threaded Anodes
NOTE: The 2−1/2 in. hex is threaded into a bushing
that should remain on the pump. Be sure to restrain
the bushing when removing the 2−1/2 in. hex.
Unscrew the 2−1/2 in. hex from the pump. If the zinc
elements require replacement, unscrew the hex head cap
screw.
NOTE: The screw was installed using thread sealant
so higher force than normal may be necessary to
remove.
Replace one or both elements as necessary. Install the
hex head screw using Loctite 242 (blue) on the screw
threads. Remove any paint or corrosion from the face
around the NPT tap on the pump. Apply thread sealant to
the threads and screw the 2−1/2 in. hex into the pipe tap
until tight.
Optional Zinc Anodes
Twice per year, remove the anodes and check for erosion
of the zinc elements. Replace the zinc elements if more
than half of either of the zinc elements has eroded.
Anodes are normally mounted on the pump intake piping,
but they may also be installed in the discharge piping if no
intake mounting locations were available. Physical mounting of the anode may be via an NPT tap or bolt−on flange
as described below.
Figure 7. Threaded Anodes
NOTE: The zinc must make contact with water to be
effective. Do not paint or use any other coating on the
zinc elements.
Bolt−on Anodes
Unscrew the (4) hex head screws from the pump. If zinc
elements require replacement, unscrew the hex head cap
screw.
NOTE: There is no need to remove the threaded
anode adapter from the anode flange for zinc element
replacement. The screw was installed using thread
sealant so higher force than normal may be necessary
to remove.
Replace one or both elements as necessary. Install the
hex head screw using Loctite 242 (blue) on the screw
threads. Mount the anode assembly back on the fitting.

Lubrication
Outboard Bearing
(All Models Except CSD and CSH)
Extra Pressure Stage Bearing
(CSH Pumps Only)
The outboard bearing is located at the end of the pump
opposite the drive end of pump.
For pumps built prior to 11/13/03: The impeller shaft is
supported at the extra pressure stage by a double row,
ball bearing. A fitting permits lubrication of this bearing.
On pumps built prior to 4/21/2006, add a good quality,
medium consistency, ball bearing grease through the
lubrication fitting until it comes out of the relief fitting.
Add grease after every 100 hours of pump operation, or
every six months, whichever comes first.
A relief groove, cut in the threads of the lubrication fitting allows surplus grease to escape without causing
excessive pressure. Add a good quality, medium
consistency, ball bearing grease until it comes out of the
relief groove of the lubrication fitting. Add grease after
every 100 hours of pump operation, or every six months,
whichever comes first.
On pumps built after 4/21/2006, the outboard bearing
is sealed and requires no lubrication.
Inboard and Outboard Bearing
(CSD Pumps Only)
The inboard bearing is located at the drive end of the
pump. The outboard bearing is located on the end opposite of the drive end.
For pumps built after 11/13/03: Lubrication of bearing
is not required as the bearing is a sealed self−lubricating
design. Note that the pumps upgraded in the field to the
sealed self−lubricating design do not require lubrication.
The lube fitting should be plugged when upgraded.
Add a good quality, medium consistency, ball bearing
grease through the lubrication fitting until it comes out of
the relief fitting. Add grease after every 100 hours of
pump operation, or every six months, whichever comes
first.
Packing − Braided Flexible Graphite (BFG)
Waterous pumps use braided graphite fiber, with reinforced flexible graphite yarns and high purity graphite
filament yarns that appear on the corners as well as
throughout the body of the packing. The graphite reinforcement allows the flexible graphite yarns to provide
greater tensile strength.
CAUTION
This type of packing reduces the frictional heat created
between the shaft and the I.D. of the packing. By dissipating the heat through the cross section of the packing,
the heat is transferred to the packing gland and the seal
housing.
! WARNING
packing, transferring the heat to the packing gland
and pump body.
Packing Removal
Pump overheating hazard.
May cause damage to the pump.
Circulate enough water through the pump to prevent
overheating. Do not pressurize the pump over the
rated maximum discharge pressure of the pump.
1. Remove the unbalanced nuts, flat washers and
packing gland halves from one end of the pump.
2. Engage the pump per appropriate operating instructions. Operate the pump gradually increasing the
discharge pressure until the packing is forced out of
the stuffing box. Pressure in excess of 300 psi (20.7
bar) may be required.
3. If all the packing is not forced out, it may be necessary to remove the remaining packing by hand, using a pick or similar device. Waterous has a packing
removal tool (P/N 5782) available for this purpose.
See Figure 8.
4. Replace packing per instructions below.
! WARNING

Packing Installation
CAUTION
1. Before installing the new packing, be sure that all of
the old packing is removed from the seal housing.
Circulate enough water through the pump to prevent
overheating.
2. Be sure that the seal housing and the shaft are clean
and free of any packing residue.
3. Lightly lubricate the packing ring I.D. and O.D. with
mineral oil, automotive grease or engine oil for
installation purposes.
! WARNING
Truck Movement Hazard. May result in serious personal injury or death.
4. Make sure packing is clean.
5. Carefully install one ring of packing. With the aid of
packing glands, push the packing into the seal housing
as far as possible. Repeat this operation with each
ring, staggering the joints at least 90_ apart. Install the
packing rings until the top of the last ring is about 1/4
inch from the end of the seal housing (at least 1/8 inch
is required for the packing gland nose entrance into
the stuffing box). See Figure 9.
Stop the engine, set parking brake and chock the
wheels before going under the truck to adjust packing.
1. Engage pump per appropriate operating instructions.
Operate the pump at 150 psi (10.3 bar) for ten (10)
minutes.
CAUTION
NOTE: Be sure that the packing joints are staggered at least 90_ apart.
6. Install packing glands, nuts and washers. Tighten
gland nuts one flat beyond finger tight. See Figure 9.
NOTE: The milled slot on the nut should face the
gland.
Observe the stuffing box drip rate from the side of the
truck.
2. Observe leakage. Normal leakage is 10−120 drops
per minute. (Leakage may be at zero or diminished to
zero occasionally).
3. If drip rate is considered high, stop the engine and
tighten the packing gland nuts 1/2 to 1 flat (maximum of 1/6 of a revolution). Make appropriate adjustments starting with 1 flat, when approaching the
final adjustment reduce to 1/2 flat. This reduces the
possibility of over tightening. Tighten the gland
nuts equally to ensure that the packing gland
goes on straight. Gradually reducing leakage during the first hour of operation will result in a better
seal over a longer period of time.
Figure 9. Packing and Gland Installation
CAUTION
Stopping the leakage entirely at this point will cause
the packing to overheat.
7. Adjust packing as require per instruction below.
4. Operate the pump at 150 psi (10.3 bar) for 10 to 15
minutes to let packing run in, then observe the drip
rate.
Packing Adjustment
The pump packing is designed and adjusted to drip
slightly during operation. This is to cool and lubricate the
packing. It is desirable to adjust the stuffing box to maintain a leakage rate of 10 to 120 drops per minute when
operating at a discharge pressure of 150 psi (10.3 bar).
Leakage through the braided flexible graphite (BFG)
packing may be at zero or diminish to zero leakage and
may not respond to loosening of the packing nuts to restore leakage (see adjustment step 3). While the packing
gland and stuffing box and pump body may reach high
temperatures during this time, the impeller shaft will be
protected from heat damage.
! WARNING
packing, transferring the heat to the packing gland
and pump body.
5. Repeat steps 3 and 4 until the drip rate is acceptable.
Rev: 05/04/06
Page 23
NOTE: After adjusting the packing, the pump
must pass the following vacuum test described
below.
Page 12 of 13

24
Vacuum Test
1. Remove all caps except openings without valves.
Close all discharge, intake and drain valves and other similar openings. Operate priming device to
create a vacuum of about 22 in. Hg/.735 atmosphere
in pump, then stop primer and engine.
2. Watch the pressure gauge; if vacuum drops more
than 10 in. Hg/.334 atmospheres in five (5) minutes,
listen for air leaks around the packing gland, gaskets, valves, etc.
3. Replace gaskets, re−adjust packing, repack or otherwise repair source of trouble.
4. Repeat test.
Overheat Protection Manager (OPM)
Check the electrical circuit by pressing the test button
located on the panel plate every 100 hours of pump operation or every six months, whichever comes first.
If the light does not flash, the light bulb or flasher may
need replacement (provided all wire connections are
solid).
Butterfly Valve (BFV)
Operate valve once a week for optimal performance.

Introduction
The Waterous C10 transmission, constructed of high−
strength aluminum transmits power from the truck’s automatic transmission either to the fire pump or to the drive
axle of the truck.
This instruction is divided into four sections:
•
General Description for Transmissions
•
General Description for Accessories
•
Shifting Instructions
•
Maintenance Instructions
General Description for Transmissions
The bearings and drive chain are lubricated by a splash
and passive lubrication system. Lubrication is accomplished when spray from the chain collects in a reservoir
in the top of the case. The lubricant flows out of the reservoir, through a hose and onto the inside surface of the
chain. This ensures all pivoting components of the chain
receive lubrication.
An electronic tachometer connection protrudes from the
tachometer housing at a 45° angle. This tachometer
pick−up senses the drive shaft speed.
The shift mechanism within the transmission consists of a
sliding internally−toothed collar which is always in engagement with an externally−toothed section of the drive
shaft. A fork shifts the collar either to engage it with teeth
on the drive sprocket hub (PUMP) or to engage it with the
teeth on the coupling shaft (ROAD). When in PUMP position, the shift collar transmits power from the drive shaft
through the drive sprocket and the chain to the driven
sprocket. The coupling shaft remains stationary. When in
ROAD position, the shift collar transmits power directly
from the drive shaft through the coupling shaft to the truck
propeller shaft and drive axle(s). In this position, the pump
drive and driven sprockets remain stationary while the
drive shaft rotates.
Three shift indicator lights are furnished. Two are mounted
in the cab and the other is mounted on the operators panel. These lights indicate to the operators that the shift has
been completed into PUMP position and the truck transmission is in pumping gear.

Two series of Allison automatic transmissions are commonly used in fire trucks. Each series is available with the shift
patterns controlled hydraulically or both electronically and
hydraulically. This later type is commonly referred to as the
ATEC transmission.
In each automatic transmission, either the non−ATEC or
the ATEC, certain sequences must occur in proper order
after the pump shift control is moved to either PUMP or
ROAD position.
Split shaft pump transmissions, automatic transmissions
and engines will vary in operation due to manufacturing
tolerances, lubrication temperature, etc. This variance in
each may or may not affect the ease of completing a full
shift into either PUMP or ROAD. Operator training and experience in shifting procedures is a requirement to becoming skilled in a smooth, complete shift into either PUMP or
ROAD.
When the pump shift is activated, the operator may
hear a noise associated with the movement of the shift
unit. This does NOT mean that the shift has been completed.
After the shift to pump operation is completed, the green
PUMP ENGAGED and OK TO PUMP lights in the cab
must be on before leaving the cab to operate the pump
from the operators panel. DO NOT LEAVE THE CAB IF
THE GREEN PUMP ENGAGED AND OK TO PUMP
LIGHTS ARE NOT ON.
Some truck builders may install a manual override for the
electric or pneumatic pump shift. The controls are normally
installed from the pump transmission to the operators panel.
CAUTION
If green PUMP ENGAGED and OK TO PUMP
light are not on, momentarily shift truck transmission from pumping gear (DRIVE) to NEUTRAL,
then REVERSE, then NEUTRAL, then back into
pumping gear (DRIVE). Lights should be on. If
lights are not on, repeat procedure.
7. Increase engine speed above idle and hold for a few
seconds. Watch speedometer to make sure it shows
some value of road speed.
NOTE: Some fire trucks have a speedometer that
will not show a value of road speed in a stationary
position.
! WARNING
If the truck attempts to move, reduce engine
speed to idle. Put truck transmission in NEUTRAL and repeat shifting instructions.
8. After leaving truck cab, block wheels using wheel
chocks.
9. To confirm that the pump is engaged:
S THROTTLE READY light on operator’s panel
is illuminated.
S
Pump discharge pressure registers on gages.
S
Other safety interlocks are activated.
Shift to ROAD as follows:
! WARNING
1. With engine speed at idle, put truck transmission in
NEUTRAL.
2. When speedometer slows to zero, move pump shift
control to ROAD position.
3. Engage truck transmission (DRIVE).
Unexpected Truck Movement.
May result in serious personal injury or death.
Failure to properly shift transmission in accordance to the transmission operating instructions
may result in unexpected truck movement which
may result in serious personal injury or death.
CAUTION
Shift to PUMP as follows:
1. Bring truck to complete stop.
2. Reduce engine to idle speed, put truck transmission
into NEUTRAL.
3. Set truck parking brake.
4. Move pump shift control to PUMP position.
NOTE: Green PUMP ENGAGED light may not illuminate.
5. Shift truck transmission into pumping gear (DRIVE).
CAUTION
6. Green PUMP ENGAGED and OK TO PUMP lights
should be on.
If you hear a loud grinding noise when you attempt
to move the truck, the shift to ROAD has not been
completed. Shift into NEUTRAL, wait for grinding
noise to stop and re−engage truck transmission.
If grinding is a common occurrence after Step 3 is performed, it may be prevented by shifting the truck transmission into NEUTRAL, then to REVERSE, back to NEUTRAL and finally to DRIVE.
4. After shifting the truck transmission to DRIVE, release
the parking brake and move the vehicle forward to confirm a shift to ROAD has been completed.
Shifting truck transmission into pumping gear
(DRIVE) above engine idle speed may cause
damage to the equipment.

If the vehicle builder has provided a means to manually
override the pneumatic pump shift, the override control
will be located at the operators panel or in the cab. The
override control will consist of a rod to the panel or a
cable or rod mechanism to the inside of the cab. The rod
or cable will be attached to the shift arm on the pump
transmission.
NOTE: This instruction is written based on an override control rod directed to the operators panel from
the short arm of the lever on the pump transmission.
Other rod or cable arrangements may require reversal
of stated action to accomplish the desired shift.

Maintenance
Indicating Lights Operation
Tachometer Readings
Check the operation of the pump shift indicating lights at
least weekly as follows:
Electric Tachometer:
NOTE: Block wheels with wheel chocks before beginning.
1. With the pump in the ROAD position, truck transmission in NEUTRAL and the parking brake engaged,
ensure that the PUMP ENGAGED and OK TO PUMP
lights in the cab are off.
2. Shift to PUMP following the shifting instructions
section of this document.
a. Ensure that the green PUMP ENGAGED and OK
TO PUMP lights in the cab are on.
b. Ensure that the green THROTTLE READY light
on the operator’s panel is on.
To verify input shaft speed, take a frequency reading from
the tachometer sensor. Multiply frequency reading (Hz) by
1.5 for shaft speed. The impeller shaft speed can be calculated by multiplying the input shaft speed by the ratio of
the pump transmission.
Fluid Levels
1. Check fluid level monthly by removing fluid level plug
at rear of case. The fluid should be level with bottom
of hole.
A sight plug is also provided for this purpose, and the fluid
level should be visible thru this plug.
CAUTION
3. Apply the service (foot) brake and release the parking
brake.
a. Ensure that the green OK TO PUMP light in the
cab is off.
on the operator’s panel is off.
4. Engage the parking brake and shift truck transmission
to NEUTRAL.
a. Ensure that the green OK TO PUMP light in the
cab is off (automatic truck transmission only).
5. Shift to ROAD following the shifting instructions
section of this document.
a. Ensure that the green PUMP ENGAGED and OK
TO PUMP lights in the cab are off.
If fluid level is low, locate source of leak and
repair. If fluid level is high, loosen drain plug until
fluid drops to proper level. If excessive water
drains out, change fluid and determine source of
water leakage, and repair.
NOTE: Fluid temperature should not exceed 250° for
an extended period of time or premature seal wear
and damage may occur.
Fluid can be added thru the fluid level hole or by removing
the breather and adding fluid thru this opening. Any type
of automatic transmission fluid (ATF) can be used.
2. Change fluid twice per year or after each 100 hours of
operation, whichever comes first. Clean the breather
and magnetic drain plug thoroughly whenever the
transmission fluid is changed.

Before any centrifugal pump can be operated, it must be
primed. Priming is the process of replacing air in the
intake lines and portions of the pump with water. If the
pump is to be operated from draft, priming must be done
by means of a positive displacement pump, or some other
device for creating a partial vacuum. Also, when pumping
from a water tank, priming will be accomplished more
quickly and positively if a priming device is used. Priming
will occur naturally when pumping from hydrants or in
relay, because inlet water pressure is high enough to force
air out of the pump and intake lines, providing a discharge
line is opened to permit the air to escape.
A Waterous priming system consists of a priming pump
and a priming valve. The priming pump draws air out of
the centrifugal pump through the priming valve. The priming valve must be open when priming the pump and then
closed when the pump is fully primed (pumping water with
all air removed).
Optional Priming Lubricant
Lubricant may be used to help seal and lubricate the priming pump.
Pumping from Draft
To obtain a quick prime & maintain pump performance:
d.) Always use an intake strainer or screen.
a.) Position pump as near as possible to water supply.
e.) Immerse intake strainer at least two feet below water
surface to prevent pump from drawing air. (Whirlpools
forming above intake strainer indicate that strainer is
too close to surface of water.)
b.) Avoid humps or sharp bends in intake hose. Make
sure no part of hose is higher than pump intake inlet.
(Air pockets in intake hose may cause loss of prime or
erratic pump action and may reduce pump capacity.)
c.) Make sure all intake connections are tight and discharge valves are closed.
f.) Make sure intake strainer is far enough from bottom to
prevent pumping sand, gravel or other foreign matter.

Rotary Vane Priming Pump − VPO, VPOS Models
Rotary vane priming pumps are available separately
mounted (model VPOS) or transmission mounted (model
VPO). The VPO and VPOS models are driven by an electric motor. The VPO and VPOS models each contain one
eccentric rotor with four vanes that slide in and out of the
rotor.
Figure 2. Rotary Vane Priming Pump
As the rotor turns, air is drawn from the priming valve inlet
due to the vacuum created behind the priming pump. As
the priming pump evacuates the air from the lines and the
main pump, atmospheric pressure forces water into the
pump.
An optional lubricant tank is available for use with VPO/
VPOS models to provide additional lubrication and sealing.

This electric motor driven rotary vane primer is used for
separately mounted applications. With the priming valve, it
forms a complete, dependable priming system.
IL2067
Outlet to Atmosphere
Priming Valve
The priming valve consists of a stainless steel valve stem,
spring and pressure disk in a plastic valve body. A rubber
disk forms the seat for the valve stem and also forms a
seal between the priming valve inlet and the pump body. A
rubber diaphragm forms a seal which allows the valve to
open and close while isolating the interior of the priming
valve from atmospheric pressure
The priming valve is attached directly to the pump body on
CM and CS models. A bronze adapter allows the priming
valve to be installed on all other pumps and also facilitates
remote mounting of the valve.
The priming valve opens automatically during pump priming. When the valve is open, it allows air to flow from the
various pump passages to the priming pump. Once the
pump is primed, the priming valve closes automatically
when the primer is deactivated.

Operating Instructions
Models VPO, VPOS (Electric Operation)
1. Close discharge valves, drain valves and all other
openings.
CAUTION
Operating the priming pump for more than one minute continuously may damage the electric motor
and/or motor solenoid.
2. Make sure all intake connections are tight.
3. Operate priming pump until it discharges a solid
stream of water through its discharge outlet.
NOTE: If priming pump does not prime main pump
and discharge a steady stream of water within 30
seconds (1250 gpm or smaller) or 45 seconds
(1500 gpm or larger), stop pump and determine
cause of problem. (An additional 15 seconds may
be required if the truck is equipped with a 4 inch
or larger front or rear intake pipe.)
4. After main pump is primed, release valve control.
NOTE: The motor and solenoid are NOT rated for
continuous duty. If possible, allow primer to be
OFF for a minimum of one minute between uses.
Manual (Hand) Primer
1. Close discharge valve(s), drain valves and all other
openings.
2. Make sure all intake connections are tight.
3. Open priming valve.
4. Start main pump and immediately begin pumping the
primer handle (to minimize time the pumps runs dry)
until water begins exiting the primer outlet.
5. Close priming valve and open main pump discharge
valve(s).
Maintenance Instructions
Priming Pump
Testing
During operation of VPO model with optional lubricant
tank, lubricant from the priming tank lubricates the priming
pump. The priming pump should be operated weekly
to cycle fresh lubricant through the primer. This cycling
is of particular importance when using biodegradable lubricant, since the biodegradable properties allow it to break
down quickly and lose its lubricating qualities. On rotary
vane primers only, an orifice is in the lubricant line where it
enters the priming pump head, to prevent excessive
amounts of lubricant entering the pump and reducing its
performance. Make sure clean lubricant is used in the
priming tank and make sure the orifice is always open.
Priming Valve
After long service, normal wear of the wave spring and
seals may prevent air sealing of the valve. Replace wave
spring and seals if any signs of leakage are discovered. A
repair kit is available from the Waterous Company.
Priming Tank
A vent hole is located in the elbow on top of the priming
tank to break the syphon and stop the flow of lubricant
after priming. The hole should be kept open at all times,
but do not enlarge it.
Once a month, perform the following vacuum test.
Remove all caps except openings without valves. Close all
discharge, intake, drain valves and other similar openings.
Operate priming device to create a vacuum of about 22 in.
Hg in pump, then stop primer and engine.
Watch pressure gage; if vacuum drops more than 10 in.
Hg in 5 minutes, listen for air leaks around packing glands,
gaskets, valves, etc.
Replace gaskets, repack or otherwise repair source of
trouble.
Rotor Clearance Adjustment
All Waterous priming pumps are factory tested and will
draw a minimum of 22 In. Hg vacuum. After prolonged
service, the rotor to pump clearance may increase because of wear, resulting in lower vacuum.
On VPO models, if maximum vacuum falls below 22 In.
Hg., inspect primer for wear of the housing, vanes, rotor
and seals. Replace as needed.
Vanes
Refill priming tank as needed with lubricant.
If dispensing priming lubricant into the environment, always
use a biodegradable or non−toxic lubricant. Biodegradable /
non−toxic Prime−Safet is available from Waterous.
Use of rotary vane primers will cause vane wear. If wear is
excessive, vacuum levels will decrease. Periodic replacement of vanes and seals is required to maintain acceptable vacuum levels. Contact Waterous service for replacement kits.
NOTE: If 30 weight motor oil is used, it is recommended that a catch pan be used under the primer to
collect the used oil so it can be disposed of properly.

Service Suggestions
Models VPO and VPOS
If the priming system fails to operate properly, refer to the
troubleshooting guide in F−1031, Section 1000 for the
possible cause and suggested remedy. If the cause of the
failure cannot be determined using the troubleshooting
guide, the following Service Suggestions should help locate the cause of the malfunction. Go through each step in
sequence to check out all the components of the priming
system, or until the cause of the malfunction is located.
7. Check for primer motor function in the following manner:
a.) With the motor disassembled from the priming
pump, manually rotate the motor shaft to make sure
it turns freely. If it does not, replace the motor.
b.) Using the correct battery (12V or 24V) for the application, attach a ground cable (6 AWG or heavier)
from the negative, “−”, battery terminal to the ground
post on the primer motor (see Figure 3 or 5). Connect the positive, “+”, battery terminal to the solenoid “HOT” terminal, again using a 6 AWG or heavier cable.
1. Make sure battery is properly charged. If battery is in
low state of charge, it may be difficult to operate the
priming pump at proper speed.
2. Check all wiring to the priming pump and valve for
loose terminals, damaged insulation, or broken wire
strands − especially near terminals.
! WARNING
Solenoid Motor Testing Hazard. Improper wiring
may cause the jumper wire to become very hot,
resulting in burns to fingers or hands.
To prevent the jumper wire from overheating on 24V
motors, DO NOT place the jumper wire on the solenoid ground terminal (small terminal with wire attached).
3. Check that the correct cable size is used (see Table 1
and Table 2).
4. Check for proper grounding of the motor. On VPO
models, there is a ground stud on the side of the motor that should be connected with a ground cable to
the truck chassis.
5. If priming pump still does not operate, remove priming
motor. Step 6 will help troubleshoot the priming pump,
and step 7 will help troubleshoot the motor.
a.) VPO models − There are two cast parts that make
up the priming pump, the part attached to the motor
should not be removed from the motor.
6.
For proper function of the priming system, always follow
the Maintenance Instructions section of this document.
The following are possible priming pump−related causes
of low vacuum levels or a non−functioning priming pump:
c.) Check for motor solenoid function by connecting a
jumper between center (small) and hot terminals of
solenoid (see Figure 5); the motor should run. Disconnect the jumper. If the motor ran with the jumper
installed, go to step 8.
Figure 5. Solenoid
Center (Small)
Terminal (24V Motor)
Center (Small)
Terminal (12V Motor)
a.) VPO primers are made of corrosion−resistant materials, but abrasives passing through the primer
can damage the corrosion resistant surfaces.
Clean the priming pump surfaces to remove corrosion, or replace worn parts.
b.) Stuck or broken vanes. If primer is not used regularly, corrosion and/or the breakdown of biodegradable lubricants can cause vanes to stick; foreign objects can enter the primer and cause a
vane to break; or sand can damage the rotor and
inside walls of the primer, not allowing the vanes
to slide freely. Clean the inside of the primer and
replace vanes or worn parts as needed.
c.) Inside walls of primer damaged from sandy water. A
tight fit between the vanes and smooth primer walls
are required for high vacuum levels. Damage to this
smooth surface (and smooth vane edges) causes a
loss of the required tight fit. Replacement of damaged parts is usually required.

d.) If motor does not run, temporarily place a heavy
jumper (6 AWG or heavier) firmly across hot and
cold terminals of solenoid. If the motor then runs,
check that the buss bar connections are tight. If
connections are good, the solenoid is probably
defective and should be replaced.
e.) If priming motor still does not run, connect a
heavy jumper directly between positive “+”, battery
terminal and “HOT“ post of motor.
41
8. If the priming motor operated with jumper connected
between center (small) and hot terminals of solenoid,
control switch or switch wiring may be defective. To
check switch, connect a jumper to its terminals. If
priming motor operates with switch bypassed, switch
is defective and should be replaced. If priming motor
does not operate with switch bypassed, check wiring
from switch to solenoid.
f.) If motor does not run, replace or rebuild it. If motor
does run with jumper connected, check cable
between battery and priming motor solenoid.

WARNING
When operating the pump, be sure to open at least one discharge valve
slightly to prevent the pump from overheating. If the pump runs for a few
minutes completely closed, it may heat the water enough to scald someone when the valve is opened. Overheating can damage the packing,
seals and other pump parts. If the apparatus builder has installed a by−
pass system or other provision designed to prevent overheating, opening
a discharge valve may be unnecessary.
WARNING
43

General Overhaul Information
Tools and Equipment
Bearings, Gaskets, Seals and O−rings
The following tools and equipment may be needed to overhaul a pump:
1. Usual automotive mechanic’s hand tools.
2. An arbor press for assembling or disassembling components.
3. An engine lathe for turning impeller hubs.
4. A suitable hoist and slings.
5. Torque capability up to 325 lb−ft.
Parts of this nature are frequently damaged during removal or disassembly. In addition, they sometimes deteriorate or lose their effectiveness because of age or misuse. Replacing these parts whenever overhauling a
pump is a good policy.
While no special tools and equipment are required, a few special items are
illustrated or described so the mechanic can make them or they are available from the apparatus manufacturer or the Waterous Company. These
special items are not absolutely necessary, but they will make the mechanic’s work much easier.
Impeller Shafts
Examine shaft for severe scratches, grooves or corrosion − especially under packing or mechanical seals. If scratches are not severe, and are not
under packing and seals, clean them with a fine−cut file. Grooves are usually permissible if they are not sharp or too deep. Even slight longitudinal
scratches will cause leaks and should be removed.
Installing Ball Bearings
Cleaning
Gaskets
The continued satisfactory operation of a pump depends to a great extent
upon the cleanliness of its internal parts. Sand, dirt or other abrasive material will wear gears and related parts. Before disassembling a pump for
repairs, be sure to clean its exterior. Make sure the working space,
benches and tools are clean. Use only clean, lint−free cloths to wipe off
components. Before reassembling a pump or its components, be sure to
clean them thoroughly.
CS ’04 Pumps (Pumps built after March, 2005)
Page 48
Pump Bodies and Impellers
Flush out these components and related parts with clean water and
remove loose scale, caked sediment, etc. Be sure to remove all traces of
old gaskets. Examine pump bodies, covers, adapters and fittings for
cracks, severe corrosion or other damage. Almost all damage to these
parts results from improper use or maintenance, or from freezing. Replace
defective parts.
48
Before disassembling a pump, test it thoroughly, if possible, and record the
results. A comparison of this test with periodic tests recommended in form
F−1031, Section 1000 can often reveal specific pump troubles. Excessive
speed, for instance, indicates that impellers and/or wear rings are probably
worn.
Most Waterous pumps are designed so that ball bearings fit tightly on their
shafts and have relatively loose fits in the bearing housings. When mounting these bearings on shafts, always apply force to the inner races. When
bearings have a tight fit in the housings, and a heavy force is necessary to
install them, be sure to apply force only to the outer bearing races. For
either type of fit, applying force to the wrong bearing race may damage the
balls and race.
Preliminary Testing
For ease of installation, the CS pump uses a body molded gasket design.
The molded gasket, made of nitrile rubber, fits into a channel in the pump
body.
CS ’93 Pumps (Pumps built from 1994 to March, 2005)
To provide added sealing for gaskets between bodies and intake adapters,
coat both sides of these gaskets with a suitable sealant. A compound such
as Permatex Super 300 is recommended for this application. Be sure all
traces of previous gaskets and sealant are removed before installing new
gaskets.

b. Position each wear ring on the impeller hub on which it was used.
Hold the wear ring firmly against one side of the hub and measure total clearance on the opposite side using a feeler gauge.
4. Flame plated impeller hub wear ring clearance is usually restored by
installing a replacement wear ring with the same dimensions as the original wear ring since most wear occurs on the wear ring, not the impeller
hub. Flame plated impellers are the numbers with the ‘‘T’’ suffix.

CS ’93 Body Gasket Installation when the Pump Body is Disassembled
(Pumps without Separate Seal Housings)
The mechanical seals should be installed in the pump after the impeller shaft has
been installed and the body halves are bolted together. Before bolting body
halves together, pay special attention to the body gasket in the seal cover area
on both ends of the pump as follows:
S
The seal chamber cover seal (square cross−section rubber ring) can seal into
gaps at the pump body split line a maximum of 1/16 inch deep. The sealing
capability depends on gap width, seal hardness, etc.
S
The pump body gasket should come as close as possible to being flush (without protruding) with the edge of the pump body at the seal chamber cover
sealing surface. It is recommended that the gasket be within 1/32 inch of the
edge of the pump body. This applies to both ends of the pump.

CAUTION
The entire mechanical seal installation procedure shall be completed without interruption. Delays may cause seal bellows to seat improperly.
Whenever a mechanical seal requires replacement, the Waterous Service Department strongly recommends replacing both seals; outboard bearing and drive end.
NOTE: Always replace the seal and bearing on outboard end first.
1. Inspect the new primary ring and stationary ring sealing surfaces. These surfaces
should be “mirror smooth” and without scratches. To identify the stationary ring
sealing surface examine the outside diameter of the ring. There is a chamfer towards the backside and the o−ring is close to the back.

The mechanical seal primary and stationary rings are made of brittle material.
The material can be cracked or chipped. Extra care must be taken when handling these rings.
On the outboard end of the pump, install the installation sleeve on the shaft which
will allow the seal to slip over the shaft shoulder. Failure to use the protection
sleeve may cause damage to the seal. Liberally coat shaft and sleeve with lubricant (supplied with kit) before installing the mechanical seal.
Place spring retainer and spring on the shaft. Coat inside of mechanical seal bellows with lubricant and push seal on with installation tool until the spring retainer
makes contact with shaft shoulder. Continue pushing the seal until the spring is
fully compressed. Remove the installation tool slowly allowing the spring to relax.
Remove the protection sleeve from the shaft (outboard end only).

6. Install the seal chamber cover on the shaft and slowly push on with installation tool. The seal chamber cover will guide the mechanical seal into
place. When the cover contacts the pump body, attach with the screws
previously removed during disassembly. On pre 93 pumps use both lockwashers and flatwashers.
NOTE: Before proceeding, both replacement seals (outboard and
drive end) and the outboard bearing should be installed. As recommended earlier, both seals should be replaced at the same time. Outboard end seal and bearing assembly should be completed first.
7. Turn impeller shaft by hand at least two revolutions in both a clockwise
and counterclockwise direction to seat seals.
81

8. Hydrostatically test pump at 150 psi (10.3 bar). Observe impeller shaft at
throttle bushing and intersection of the seal chamber cover with pump
body split line for leaks. Turn impeller shaft by hand while retaining the
hydrostatic pressure to see if there is leakage between the throttle bushing
and impeller shaft. If leakage persists, after one or two minutes of rotation
(10 to 12 turns) disassemble and inspect.

Packing − Braided Flexible Graphite (BFG)
Waterous uses a braided graphite fiber, with reinforced flexible graphite yarns
and high purity graphite filament yarns that appear on the corners as well as
throughout the body of the packing. The graphite reinforcement allows the
flexible graphite yarns to provide greater tensile strength.
This type of packing reduces the frictional heat created between the shaft and
the I.D. of the packing. By dissipating the heat through the cross section of the
packing, the heat is transferred to the packing gland and the seal housing.
!
WARNING
Packing Gland and Pump Body Temperature Hazard. May result in
serious burns.
Heat is dissipated through the cross−section of the packing, transferring
the heat to the packing gland and pump body.
Packing Removal
WARNING
CAUTION
Truck movement hazard.
May cause serious personal injury.
Stop engine, set the parking brake and chock the wheels before going
under truck to remove packing.
Circulate enough water through the pump to prevent overheating. Do
not pressurize the pump over the rated maximum discharge pressure
of the pump.
!
2. Engage the pump per appropriate operating instructions. Operate the
pump gradually increasing the discharge pressure until the packing is
forced out of the seal housing. Pressure in excess of 300 psi (20.7 bar)
may be required.
3. If all the packing is not forced out, it may be necessary to remove the remaining packing by hand, using a pick or similar device. Waterous has a
packing removal tool (P/N 5782) available for this purpose, see Figure 7.

1. Remove the unbalanced nuts, flat washers and packing gland halves from
one end of the pump.
4. Replace packing per instructions below, repeating the procedure for the
opposite end of the pump.

7. Adjust packing as required per instructions on the next page.
1. Before installing the new packing, be sure that all of the old packing is removed from the seal housing.
Packing Adjustment
2. Be sure that the seal housing and the shaft are clean and free of any
packing residue.
3. Lightly lubricate the packing ring I.D. and O.D. with mineral oil, automotive
grease or engine oil for installation purposes.
4. Make sure packing is clean.
5. Carefully install one ring of packing. With the aid of packing glands, push
the packing into the seal housing as far as possible. Repeat this operation
with each ring, staggering the joints at least 90_ apart. Install the packing
rings until the top of the last ring is about 1/4 inch from the end of the seal
housing (at least 1/8 inch is required for the packing gland nose entrance
into the stuffing box), see Figure 8.
NOTE: Be sure that the packing joints are staggered at least 90_
apart.
The pump packing is designed and adjusted to drip slightly during operation.
This is to cool and lubricate the packing. It is desirable to adjust the stuffing
box to maintain a leakage rate of 10 to 120 drops per minute when operating
at a discharge pressure of 150 psi (10.3 bar).
Leakage through the braided flexible graphite (BFG) packing may be at zero
or diminish to zero leakage and may not respond to loosening of the packing
nuts to restore leakage, see Adjustment Step 3. While the packing gland and
stuffing box and pump body may reach high temperatures during this time, the
impeller shaft will be protected from heat damage.
CAUTION
Circulate enough water through the pump to prevent overheating.
NOTE: The milled slot on the nut should face the gland.

6. Install packing glands, nuts and washers. Tighten gland nuts one flat beyond finger tight, see Figure 8.
Truck movement hazard.
May cause serious personal injury.
Stop engine, set the parking brake and chock the wheels before going
under truck to adjust packing.
1. Engage pump per appropriate operating instructions. Operate the pump at
the capacity pressure shown on the serial plate for ten (10) minutes.
CAUTION
Observe the stuffing box drip rate from the side of the truck.
2. Observe leakage. Normal leakage is 10−120 drops per minute.
!
WARNING
Packing Gland and Pump Body Temperature Hazard. May result
in serious burns.
Heat is dissipated through the cross−section of the packing, transferring the heat to the packing gland and pump body.

3. If drip rate is considered high, stop the engine and tighten the packing
gland nuts 1/2 to 1 flat (maximum of 1/6 of a revolution). Make appropriate
adjustments starting with 1 flat, when approaching the final adjustment
reduce to 1/2 flat. This reduces the possibility of over tightening. Tighten
the gland nuts equally to ensure that the packing gland goes on
straight. Gradually reducing leakage during the first hour of operation will
result in a better seal over a longer period of time. Adjust the drip rate on
one stuffing box until the appropriate rate is obtained, then proceed to the
other end of the pump.
CAUTION
Stopping the leakage entirely at this point will cause the packing
to overheat.
4. Operate the pump at the capacity pressure shown on the serial plate for
two (2) minutes to let packing run in, then observe the drip rate.
5. Repeat steps 3 and 4 until the drop rate is acceptable.
NOTE: After adjusting the packing, the pump must pass the following vacuum test described below.
Vacuum Test
1. Remove all caps except openings without valves. Close all discharge, intake and drain valves and other similar openings. Operate priming device
to create a vacuum of about 22 in. Hg/.735 atmosphere in pump, then stop
primer and engine.
2. Watch the pressure gauge; if vacuum drops more than 10 in. Hg/.334 atmospheres in five (5) minutes, listen for air leaks around the packing
gland, gaskets, valves, etc.
3. Replace gaskets, re−adjust packing, repack or otherwise repair source of
trouble.

Introduction
This instruction provides the necessary steps required to overhaul the C10 transmission. These instructions are divided into Disassembly and Reassembly
sections. Also, refer to the Service Parts List (SPL documents) furnished with your C10 transmission to aid in further part identification and repair parts ordering.
General Description
The Waterous C10 is a chain driven transmission with a housing
constructed of high−strength aluminum. Drive and driven sprockets are
made of hardened steel and have ground bores. Shafts are made of alloy
steel forgings, hardened and ground to size. A passive lubrication system
eliminates the need for a separate oil pump. The shift mechanism is a
constant−mesh, two−position sliding collar that engages all teeth simultaneously.
Disassembly
Before beginning the disassembly process, drain the fluid from the transmission by removing the drain plug. Note that these instructions apply for out of
chassis overhaul of the unit.
Propeller Shaft Disconnect and Accessory Removal
Shift Unit
Disconnect the propeller shafts.
Remove the pneumatic shift unit from the transmission by removing the
two hex nuts and washers. Note that the adjusting screw retainers are exposed when the shift unit is removed. Special care should be taken to prevent the retainers from falling out of the transmission.
Electrical Connections
Disconnect the tachometer cable, shift wiring and electric shift override
linkage.

Guidelines for Installing Ball Bearings, Oil Seals and O−Rings
Installing Ball Bearings
Installing Oil Seals
Keep new ball bearings wrapped until they are to be installed. When pressing the
ball bearing on a shaft or into a bore, coat appropriate surfaces with grease.
Shaft − grease shaft and ball bearing bore.
Bore − grease bore and outside of diameter of ball bearing.
Always apply force to the inner race of a ball bearing when pressing it on a
shaft and to the outer race if pressing into a bore. Press evenly with a piece of
pipe or tube which just clears the shaft.
NOTE: Wherever silicone or sealant is referenced, use Loctite Ultra Blue
RTV Silicone Sealant or equivalent, unless otherwise specified.
Before installing a new oil seal in its housing, apply a thin coat of sealant to
housing oil seal seat. Be sure that the seal, shaft and housing are clean. Always install a seal with the seal lip facing in. Lubricate seal lip with light oil
before installing shaft. Apply force to the outer edge of the seal and press in
evenly.
Installing O−Rings
Grease new O−rings prior to installation. This will aid in the installation as well
as preventing damage to the O−ring.

Figure 49. Assembling Coupling Shaft Housing to Case
Coupling Shaft Housing Assembly to Case Assembly
The driveline assembly was factory shimmed to limit the axial float of the
drive line. If any of the drive line parts have been changed, it may be necessary to change the total thickness of shims between the coupling shaft
housing and the transmission case. Shims are color coded for thickness as
follows:
.005”
Blue
.007”
Natural
.010”
Brown
Breather
The correct thickness of shims can be determined as follows:
Hose Assembly
1. Install coupling shaft and housing assembly with no O−ring or shims
between the housing and case. Lightly tighten the cap screws evenly
and tap the end of the coupling shaft with a soft mallet to force the
drive line all the way forward. Do not overtighten causing bending or
breakage of the coupling shaft housing.
Shims
(.005 − .010”)
Axial float
Lock Washer
3. Remove the coupling shaft assembly from the case after measuring
the gap.
NOTE: Field conditions may make it difficult to determine the correct
amount of shims. If in doubt, add another .005 in. shims. No harm will
result from a small amount of additional axial float but ball bearing
life will be shortened if ball bearings are excessively preloaded.
116
Page 116
2. Measure the gap between the housing and case in several places to
assure a uniform gap and add .005 in. This will be the total thickness
of shims needed to provide the recommended axial float of .005 − .010
in.
Hex Hd Screw
4. Install the correct amount of shims on the coupling shaft housing or if
all original parts are being used, reinstall original shims on coupling
shaft housing.
5. Coat O−ring with grease and install O−ring on housing.
6. Install the coupling shaft housing assembly.
Breather and Hose Assembly Installation
7. Install fasteners.
1. Apply thread sealer to breather and install.

Please read through the safety information in your operation and maintenance instructions prior to using your Waterous
pump.
Setup
1. Move the apparatus to a safe operating area.
2. Set the apparatus parking brake.
3. Place wheel chocks.
4. Open the tank−to−pump valve.
5. Open the tank fill valve half−way.
Weekly Performance Checks
The following procedures should be performed at least weekly.
. Priming System
1. Check priming lubricant level (if applicable).
2. Fill priming lubricant tank with Prime−Safet lubricant (if applicable).
3. Operate the pump priming system(s) for twenty seconds.
Monthly Performance Checks
The following procedures should be performed at least monthly.
. Pump Shift Unit
1. Engage the pump per the transmission operating instructions.
2. Check all shift indicating lights for proper operation.
. Transfer Valve Actuator
1. (Model CP−3 pumps only) Add 1 oz. of calcium−based water pump grease through lube fitting.
2. With the pump at idle, operate the transfer valve between pressure (series) and volume (parallel) for at least two cycles.
3. Check all indicating lights for proper operation.
. Discharge Relief Valve System
1. Increase the pump discharge pressure to 150 psi.
2. With the pilot valve OFF, remove the strainer assembly. Clean the strainer and the orifice in the end of the rod.
3. Cover the strainer opening with your hand and slowly turn the pilot valve ON and OFF several times. Water should flow
from the strainer opening in the ON position and the relief valve should open (amber light). Water flow should stop and
the relief valve should close (green light) in the OFF position.
4. Check the strainer O−rings and replace if required; replace the strainer assembly (hand−tight only).
5. With the pilot valve OFF, turn the pressure adjustment handle counterclockwise until it stops.
6. Slowly turn the pilot valve ON. The relief valve should open (amber light) and the pump discharge pressure should drop.
7. Slowly turn the pilot valve OFF. The relief valve should close (green light) and the pump discharge pressure should rise
back to 150 psi.
8. Repeat steps 6 and 7 until the system responds quickly when turned ON and OFF.
9. Reset the pilot valve to the desired setting and decrease the engine speed to idle.
. Disengage the pump per the transmission operating instructions.

Monthly Performance Checks Continued
. Discharge Valves
1. Open all discharge valve drains and disconnect any pre−connected fire hose.
2. With the pump flooded, open and close each discharge valve repeatedly until it operates smoothly.
3. After water flow has stopped, close all drains and reconnect the hoses.
. Pump Master Drain
CAUTION
Never open or close the pump drain valve while the pump is under pressure. Doing so may result in valve seal failure.
1. Open and close the drain valve several times to allow debris to flush after each pumping operation.
2. Refill the apparatus water tank.
. Dry Vacuum Test
1. Close the tank−to−pump valve and tank fill valve
2. Remove all caps, except on openings without valves.
3. Close all intake, discharge and drain valves.
4. Operate priming system to produce a vacuum of at least 22” Hg.
CAUTION
Operating the priming pump for more than one minute continuously may damage the electric motor.
5. Watch the intake (compound) gauge. Vacuum should not drop more than 10” of Hg in five minutes.
. Intake Relief Valve System
1. Clean the pilot valve strainer once per month or as needed. Remove the screen using a 24mm wrench. Clean and
re−install.
2. Remove and clean the throttle screw from the pilot valve. If the bore is plugged, it can be flushed out with water.
3. Test the intake relief valve system with a pressurized water source capable of supplying continuous flow at 60 to 100 psi.
a. Set the pilot valve slightly above the source pressure and apply this pressure to the pump intake. The relief valve
should remain closed.
b. Reduce the pilot valve setting to slightly below the source pressure. The relief valve should open, “dumping” a large
volume of water.
c.
Reset the pilot valve above the source pressure. Relief valve should close.
. Miscellaneous Items
1. Check the pump transmission lubricant level and refill if necessary.
2. Model KC Transmission only: Check the fluid level in the hydraulic shift reservoir and refill if necessary.
3. Check the condition of all intake strainers and anodes; replace if necessary.
The fire pump system should be performance tested on an annual basis per NFPA 1911, Standard for Service Tests of Fire
Pump Systems on Fire Apparatus.
