SAFETY INSTRUCTIONS
1. Read, understand and follow the safety and operating instructions found in this manual.
Know the limitations and hazards associated with operating the machine.
2. Eye Safety: Wear an approved safety face shield, goggles or safety glasses to protect eyes
when operating the machine.
3. Grounding the Machine: Machines equipped with three prong grounding plugs are so
equipped for your protection against shock hazards and should be plugged directly into a
properly grounded three-prong receptacle in accordance with national electrical codes and
local codes and ordinances. A grounding adapter may be used. If one is used, the green
lead should be securely connected to a suitable electrical ground such as a ground wire
system. Do not cut off the grounding prong or use an adapter with the grounding prong
removed.
4. Work Area: Keep the floor around the machine clean and free of tools, tooling, stock scrap
and other foreign material and oil, grease or coolant to minimize the danger of tripping or
slipping. Van Norman/Kwik-Way recommends the use of anti-skid floor strips on the floor
area where the operator normally stands and that each machine's work area be marked off.
Make certain the work area is well lighted and ventilated. Provide for adequate workspace
around the machine.
5. Guards: Keep all machine guards in place at all times when machine is in use.
6. Do Not Overreach: Maintain a balanced stance and keep your body under control at all times.
7. Hand Safety: NEVER wear gloves while operating this machine.
8. Machine Capacity: Do not attempt to use the machine beyond its stated capacity or
operations. This type of use will reduce the productive life of the machine and could cause
the breakage of parts, which could result in personal injury.
9. Avoid Accidental Starting: Make certain the main switch is in the OFF position before
connecting power to the machine.
10. Careless Acts: Give the work you are doing your undivided attention. Looking around,
carrying on a conversation and horseplay are careless acts that can result in serious injury.
11. Job Completion: If the operation is complete, the machine should be emptied and the work
area cleaned.
12. Disconnect All Power and Air to Machine before performing any service or maintenance.
13. Replacement Parts: Use only Van Norman/Kwik-Way replacement parts and accessories;
otherwise, warranty will be null and void.
14. Misuse: Do not use the machine for other than its intended use. If used for other purposes,
Van Norman/Kwik-Way Products Inc. disclaims any real or implied warranty and holds itself
harmless for any injury or loss that may result from such use.

FILL COOLANT TANK
1. Add ½ quart of coolant additive (Part # 794-8011-40) to the coolant reservoir bucket and fill
with water. Slide bucket back under machine, positioning it under the coolant drain hose,
and place pump into reservoir bucket. Figure 10
Figure 10
2. After machine is wired, turn on coolant pump and set coolant flow by turning valve located
outside the sheet metal coolant shroud.
CAUTION: Excessive buildup of grinding sludge in the coolant may cause premature failure of
the coolant pump. Clean out coolant tank every 25-30 flywheels.
WIRE MACHINE
1. Electrical hookup to machine should be done by a qualified electrician. The power source
supplied must be the same as specified on the serial plate which is mounted on the back of

rear of the column slide. Refer to the diagram for a three phase hookup and a single phase
hookup. Figures 12 and 13. The FG4000 also requires a 120 volt power source for
operation. A power cord is provided with the machine and can be plugged into a 120 volt
outlet.

ROTATION CHECKS
Check rotation of the table and grinding motors on 3 Phase Flywheel Grinders.
1. Turn on table motor. Table should rotate in clockwise direction when viewed from the top
(see arrow label on edge of table). Turn on grinding motor. Motor should rotate in clockwise
direction when viewed from the top (see arrow label on front of motor).
2. On 3 Phase machines, if both the table motor and the grinding motor are rotating the
opposite direction, interchange any two of the three HOT LEADS of the 3 Phase connection
at the electrical box. Figure 12. DO NOT INTERCHANGE GROUND WIRE. If the rotation
is correct on one motor, but not the other, contact technical assistance at Van Norman/KwikWay Products.
3. On 1 Phase (Single Phase) machines, if rotation is not correct, contact Van Norman/KwikWay Products for assistance.
OPERATION
1. Remove the coolant shroud door at the front of the machine using the two handles. Select a
grinding wheel according to the material to be ground.
2. Install the grinding wheel. Figure 14. Tighten to 150 lbs. Occasionally it may be necessary
to use a wheel spacer in order to reach to the bottom of a recessed flywheel. Use the
spacer and the longer cap screw provided and install. Figure 14
Figure 14
3. When a new grinding wheel is installed, or a wheel is re-installed, the wheel should be
dressed or “trued up.” Figure 15.
NOTE: CBN abrasives do not require truing.
Van Norman

WHEEL DRESSER
1. Since it may be impossible to accurately match the grinding wheel material and hardness to
the metal alloy being ground, it may become necessary on some applications to dress the
grinding wheel after use. The purpose in dressing the wheel is to remove that portion of the
wheel’s edge which has become dull and/or clogged with particles causing a decrease in
cutting ability. A clean grinding wheel will be evident and very little heat will be generated in
the work piece. Under ideal circumstances, the grinding wheel will break down during
grinding at a rate sufficient to keep sharp, clean particles exposed on the grinding edge. If
the grinding rate decreases noticeably as evident by a decrease in the shower of sparks, it
will be necessary to dress the wheel. This should be accomplished by raising the grinding
wheel up far enough so that the dresser can swing under the wheel. The dresser height is
changed by rotating the adjustment collar. Figure 15

2. Adjust wheel guard and install shroud door for maximum protection. (No coolant is needed
for the dressing operation). Start grinding motor. Carefully swing the dresser back and forth
under the rear edge of the grinding wheel, gradually rotating the dresser adjustment collar to
raise the dresser until contact is made. Only a small amount of material has to be removed
to obtain a new grinding edge.

SETTING UP FLYWHEEL
1. To load the flywheel, remove the front coolant shroud door, release column slide lock handle
(A) and rotate column slide traverse handwheel (B) to maximize workspace. Figure 16
A
Figure 16
B
2. A cross section diagram of the general method for setting up a flywheel for grinding is
shown in Figure 17. Detailed instructions are outlined below. The accuracy of the ground
flywheel will depend to a large extent on the accuracy and condition of the surface that the
flywheel is mounted on. A flywheel cannot be expected to run true if it was ground on a
surface that was not parallel to the crankshaft mounting surface. Whenever a flywheel is
ground while mounted on a surface other than the crankshaft mounting surface, careful
inspection to assure parallelism of the two surfaces should be done.

SETTING UP FLYWHEEL (continued)
3. Clean table and adapter, then lay the proper flange adapter on table. Use the largest
possible flange adapter for maximum support. Place flywheel onto table with crankshaft
mounting surface contacting the flange adapter. Figure 18
NOTE: Make sure the C.S. mounting surface is clean and free from any nicks or burrs.
Figure 18
4. Choose proper size centering cone to fit center hole in flywheel. Select correct length
centering cone bolt. Secure to table by tightening centering cone bolt. Figure 19. If exact
centering is necessary such as on some recessed flywheels, a dial indicator may be used.
Figure 19
5. Position grinding wheel over surface to be ground and lock grinding head in place using the
column slide lock handle. Position wheel guard for maximum operator protection.
6. Replace shroud door and switch on the grinder motor, table motor and coolant pump. Direct
coolant onto work piece so it flows under the grinding wheel. Regulate amount of coolant
flow by adjusting valve on rear of shroud. Never grind without adequate coolant flow.

GRINDING FLYWHEEL
1. Feed grinding wheel downward by turning feed handle counter clockwise. Figure 20. Grind
surface until flat and free of defects or to desired depth.
Figure 20
2. Surface Finish -- Keep the grinding wheel cutting at all times, never allow the wheel to coast
for a long period of time without feeding it downward. Long periods of coasting will cause
the grinding wheel to glaze and load up.
3. The only exception to this is when it is desired to obtain a very smooth finish. A wide variety
of surface finishes are obtainable using the FG4000 without varying the grit size of the
grinding wheel. This range of surface finish is obtained by varying the pressure exerted on
the grinding wheel. A coarse finish is obtained by feeding heavily then backing off the work
piece quickly. Smoother finishes are obtained by backing off the work piece then coming
back down with a very light feed pressure.

GRINDING FLYWHEEL (continued)
4. Recessed Flywheels -- When grinding recessed flywheels, the depth dimension from the
pressure plate mounting surface to the clutch friction surface should be restored after
grinding of the friction surface. This is done by grinding the pressure plate mounting surface
an amount equal to that ground off the friction surface. The steps followed in grinding
recessed flywheels are as follows:
a. Mount flywheel on machine
b. If original equipment specs are unavailable, use a depth micrometer (Part # 794-801324) to measure depth from pressure plate mounting surface to an unworn area of the
clutch friction surface.
c. Grind friction surface to clean up.
d. Use depth micrometer again to measure new depth. Subtract original depth from this
measurement to obtain amount to be removed from pressure plate mounting surface.
e. Locate dial indicator on pressure plate mounting surface, set dial to zero.
f. Grind surface until dial indicator reading changes by the proper amount.
5. While a dial indicator or depth micrometer is used to remove a specific amount of material,
the graduated dial under the feed wheel will give the operator an approximate amount of
material removal. Figure 21. The readings of this dial will be influenced by both stock
removal and grinding wheel wear.

RADIUS CUTTER OPERATION (Optional)
Before grinding the flywheel or cutting a radius on a recessed flywheel, make certain the
flywheel is accurately centered. A dial indicator may be used. It is not necessary to use
coolant when using the radius cutter.
1. On certain applications on a recessed or stepped flywheel, it is necessary to remove the
slight radius left by the grinding wheel. This can be accomplished using the optional Radius
Cutter. Figure 22
Figure 22
2. Install the radius cutter mounting bracket as shown in Figure 23.
Figure 23
3. Mount tool bar to the mounting bracket and position.
4. After the tool bit is positioned over the desired location, lock column slide lock handle
actuate the table motor and gradually feed the grinding head down until the radius is
removed.

LUBRICATION
1. Table Support Bearing -- The FG4000 table is completely supported from below by an
integral cast iron bearing. The bearing table interface runs off a film of oil supplied by a
reservoir in the center of the base casting. The level of this reservoir must be approximately
1/16” above the surface of the table bearing (or the bottom of the table). Use Part # 7948011-55 for table lubricant only.
2. The level of the oil under the worktable is checked by removing the large flat head cap
screw from the table. A depth gauge is provided with the machine for checking the oil level
through this hole in the table. This gauge has been preset at the factor but should be
checked each time before use. The overall length of the gauge pin protruding from the
round handle should be equal to the thickness of the machine’s table. Figure 24.
Figure 24
3. The column slide ways are lubricated through four oiler cups. Figure 25. Oil daily using 30
weight motor oil.

4. Leadscrew and Nut -- Lubricate leadscrew and bronze nut as required to maintain smooth
operation with Part # 794-8011-52 leadscrew lubricant or a medium duty grease containing
graphite or molybdenum.

GRINDING MOTOR
CAUTION: Overgreasing bearings can cause premature bearing and/or motor failure. The
amount of grease added should be carefully controlled.
NOTE: If lubrication instructions are shown on the motor nameplate, they will supersede this
general instruction.
Motors are pregreased with apolyurea mineral oil NGLI grade 2 type grease unless stated
otherwise on the motor nameplate. Some compatible brands of polyurea mineral base type
grease are: Chevron SRI#2, Rykon Premium #2, Shell Oil Dolium R or Texaco Polystar RB.
Motors may be greased at 500 hour intervals, adding .30 ounce of recommended grease to
each bearing.

The oil in a new speed reducer should be changed at 250 hours of
Subsequent Oil Changes: Under normal conditions, after the initial oil change, the oil should
be changed after every 2,500 hours of operation, or every six months, which ever occurs first.
Under severe conditions such as rapid temperature changes, moist, dirty or corrosive
environment, it may be necessary to change oil at intervals of one to three months. Periodic
examination of oil samples taken from the unit will help establish the appropriate interval.
Overfilling or Underfilling: If a speed reducer is overfilled with oil, the energy used in churning
the excessive oil can result in overheating. If this occurs, shut down the drive, remove the oil
level plug and allow oil to drain until oil ceases to drain from the level hole. Reinstall the oil level
plug, and restart the drive. If the speed reducer is underfilled, the resultant friction can cause
overheating and possible damage. If this occurs, fill the speed reducer to the oil level plug hole
and check the gearing for excessive wear.

MACHINE MAINTENANCE
Coolant Tank Cleaning: Clean tank after every 25-30 flywheels.
¾Remove pump.
¾Empty, clean and flush tank.
¾Re-install pump, add ½ quart of Part # 794-8011-40 coolant additive and fill with water.
Flywheel E-Z Lock Insert: The flywheel hold down bolt threads into threaded insert located in
the center of the turntable hub. This replaceable E-Z Lock Insert is provided so that when the
threads become damaged replacement of the entire table spindle is not necessary. It is
recommended that replacement should be done before the insert’s threads are completely worn
out. An E-Z Lock Insert extractor is supplied with the FG4000 (Part # 794-8637-45).
Once a month, remove the E-Z Lock Insert (Part #794-8017-44) from the center of the table,
and coat the threads with an anti-seize lubricant. This will prevent the insert from becoming
permanently lodged in place from rust and grit.
GRINDING HEAD ADJUSTMENTS
All grinding should be done with the front edge of the grinding wheel. Insufficient frontward tilt
as evident by sparks from both the front and rear of the wheel may result in abnormal heating of
the work piece and necessitate more frequent dressing of the grinding wheel.
Checking Head Tilt: Tilt may be checked by attaching the Optional Dial Indicator and
mounting hardware to grinder motor and lowering head until indicator touches table. Figure 26.
Rotate indicator (and motor shaft) from front to back and note direction and amount of indicator
travel. Experience has shown that tilting the head of the FG4000 so that the indicator reading at
the front is .020” to .025” lower than at the rear is a good starting point. Individual operators
may want to increase or decrease tilt depending upon their own preferences. Increased tilt
should be used if higher stock removal rates are desired.
NOTE: The head tilt on your FG4000 was set at the factory at .023” tilt to the front.

GRINDING HEAD ADJUSTMENTS (continued)
Front to Rear Tilt Adjustment: Loosen the four 3/8”-16 nuts approximately ½ to ¾ turn.
Figure 27.
Tighten (or loosen) the front adjusting screw to either raise or lower the front of the grinding
wheel motor. Tighten (or loosen) the rear adjusting screw to raise or lower the rear of the
grinding wheel motor. The correct tilt may be obtained by alternately adjusting these screws.
Tighten the four hex nuts and recheck with the dial indicator that the proper adjustment has
been made.
Side-to-Side Tilt Adjustment: This adjustment will affect the flatness and/or parallelism of the
ground work piece. Shim between the motor and the motor mount bars. Figure 27. The dial
indicator reading should be .000” when swung from one side to the other.
Figure 27
Head Lock Handle Position Adjustment: Adjustment of the Kip Elsa handle. Lift up the
spring loaded handle, reposition at desired location, then release handle.

GRINDING HEAD ADJUSTMENTS (continued)
Leadscrew Backlash Adjustment: The amount of backlash in the leadscrew and nut
combination may be adjusted by tightening or loosening the cap screw through the bronze
leadscrew nut. Tightening the cap screw in the bronze nut decreases the amount of backlash.
Figure 28.
Figure 28
Dovetail Ways Gib Adjustment: If it becomes necessary to adjust the gibs on the dovetail
ways it can be done using a 3/16” hex wrench and a 9/16” open end wrench. Loosen the hex
nuts then turn the set screws in just until there is resistance. Figure 29. While holding the set
screw from turning, tighten the hex lock nut. When all screws are properly adjusted there
should be no side-to-side play in the slide and the handwheel should turn easily with only light
resistance. Over tightening the gibs will cause premature failure of the leadscrew and lead
screw nut.
