SERVICE FACTORS
The service factors that follow are adapted from AGMA.
Applications which expose the gear drive to high starting torques, extreme repetitive shock, or where high energy
loads must be absorbed as when stalling, require special consideration. Service factors for these special applications
should be agreed upon by the user and Baldor since variations of the values in the table may be required.
The service factors in the service factor table are based on the use of an electric or hydraulic motor or the use of a
steam or gas turbine as a prime mover. If the prime mover is a single or multi-cylinder engine, then the service factor
must be adjusted in accordance with the table.

▲ See Mill, Rotary
(1) Service factors for paper mill applications are applied to the
nameplate rating of the electric motor at the motor rated base
speed
(2) Using anti-friction bearings only. Use 1.50 for
sleeve bearings
(3)
When a super calender operates over a speed range of
part constant horsepower and part constant torque and the
constant horsepower speed range is greater than 1.5:1,
use a service factor of 1.00 at base speed. When operating
at constant torque over the entire speed range or when the
constant horsepower speed range is less than 1.5:1, a 1.25
service factor should be used.

▲ Minimum cooling requirements are based on an ambient temperature of 80°F (27°C) at sea level (0-2500 ft.) If your operating conditions are different, the application adjusted thermal rating must be calculated
and compared to the Thermal Rating Tables to ensure adequate cooling is provided.
† The overhung load and minimum sprocket pitch diameter are appropriate for loads applied one shaft diameter from the seal cage with a service factor of unity. When overhung load is proportional to torque (i.e.,
pinion, sprocket) adjustment to the published values must be made based on the minimum required service factor.

table on pages 72-79.)
For thermal capacities beyond the range of cooling fans,
an optional heat exchanger cooling package is available
to achieve the use of full mechanical HP rating by
lowering the oil temperature.
Specifications for the heat exchanger motor are as
follows: 1/2 HP, 60 Hz, 3 Ph, 230/460 Volt, TEFC, 56
Frame. Minimum coolant (water) flow is 3 G.P.M. based
upon a maximum water temperature of 80ºF. Minimum oil
temperature for operation is 60ºF.
The cooling package is available to cover the basic
reducer sizes CR50 through CR130. (See thermal HP
Part number 273933.

An optional dipstick is available for applications where viewing of the side oil sight plug is not possible. The dipstick
is suitable for foot mounted reducers where the foot is in the horizontal plane below the rotating shafts. Consult the
factory for applications where the reducer is mounted on an incline.
The dipstick is vented and should be installed in the existing vent hole location. The dipstick comes pre-marked and
is dependent on reducer size, output speed, and presence of fan (shaft driven or electric) accessory. The dipstick part
number can be identified from the table below.

SCOOP MOUNT MOTOR/REDUCERS
COMPATIBILITY WITH BRAKE MOTORS
DODGE MAXUM XTR Scoop Motor Mounts are avail
able for all reducer sizes ranging in motor frame sizes
from 140T to 440T. Scoop mounting your motor can
be an economical alternative to foot mounting or
where fastening the motor to a rigid foundation is not
possible. The Scoop Motor Mount Kit can be supplied
with your reducer and factory-mounted Baldor AC
NEMA motors, or may be ordered separately for use
with customer supplied AC motors.
Scoop Motor Mount kits were not designed to be
compatible with brake motors. If the application
is using a brake motor, forward brake motor
dimensions and application data to Baldor for
engineering review prior to placing order.
DRIVE SYSTEM VIBRATION
Scoop Motor Mounts are NOT recommended for
variable speed DC or AC applications. Scoop Motor
Mounts were designed for use with constant speed
motors at 1750 RPM. Use of motors with lower
base speeds increases the chance of producing
resonance. The probability of a constant speed
motor operating at resonant frequency is remote,
however, should this occur, the customer must add
stiffening supports to the scoop bottom plate to
move the resonant frequency away from the motor
operating speed. For recommended scoop mount
support, contact Baldor.
INCLUDED COUPLINGS
DODGE PARA-FLEX® couplings are standard with
all Scoop Motor Mount Kits, however, DODGE GRIDLIGN couplings are also available.
THERMAL LIMITATIONS
Thermally limited reducers should be equipped with
a cooling fan or heat exchanger as required. Refer to
pages 72-79 for thermal data. Refer to pages 43-44
for cooling fan information.
CAUTION: The customer is responsible and Baldor
expressly disclaims responsibility for isolating the Scoop
Motor Mount from any vibratory or transient load induced
by the motor or other equipment driven by the motor. The
Scoop Motor Mount is expressly not warranted against
failure or unsatisfactory operation resulting from dynamic
vibration of any form imposed upon it whether by the drive
system in which it is installed or for any other reason, no
matter how induced.
COMPATIBLE ACCESSORIES
Refer to the Accessory Compatibility Table on page 42
for other accessories that can be used in conjunction
with scoop motor mounts.
NOTE: The high speed couping may be required to
overhang the input shaft when a cooling fan or backstop is
used in combination with the scoop mount.

HD BASEPLATE ASSEMBLIES
baseplate becomes a drive package warranted as a single
system.
Heavy Duty Baseplates are rigid units fabricated of
heavy steel, providing a sturdy mounting base for motor/
coupling/ reducer combinations. This accessory is
recommended for large motors where the motor weight
exceeds the reducer weight or 700 lbs. and for variable
speed DC or AC application regardless of the motor
weight. The combination of a factory mounted Baldor only
motor, DODGE coupling, MAXUM XTR reducer and HD
HD baseplate assemblies include baseplate, Para-Flex
coupling and coupling guard.
When mounting variable speed AC or DC motors, consult
general guidelines on pages 88-89.
Consult factory for baseplate dimensions.
60
BACKSTOP ASSEMBLIES
Optional backstops are offered for service conditions that require the prevention of reverse rotation. On reducer sizes
50 through 90, the backstops are internally mounted. On reducer sizes 100 through 130, the backstops are externally
mounted on an extended high speed shaft.
NOTE: All backstops have a maximum overrunning speed limitation of 1800 RPM.
When ordering a reducer with a backstop, it will be necessary to indicate on the order the desired direction of rotation
of the output shaft, either by designating “CW” for clockwise or “CCW” for counter clockwise, when looking at the
output shaft.
WARNING: Backstops are not to be used for applications involving energy absorption and shock or torque loads
in excess of reducer ratings nor on applications such as chair lifts, amusement rides, etc., and where the safety of
property is dependent
on their function. On such
applications, other holding devices
must be provided. DO NOT
use
4

a backstop as a substitute for a brake. DO NOT use a backstop for indexing. Backstopping more frequently than five
times in an eight hour period, or less than one minute between applications, is categorized as indexing.

TORQUE METHOD OF SELECTION
TORQUE METHOD OF SELECTION
Step 1: Determine Service Factor - See pages 7-9 for electric
motor, hydraulic motor, steam turbine or gas turbine driven
applications operating up to 10 hours per day or over 10 hours
per day. If the application is engine driven, refer to table on
page 6 to convert the service factor obtained from Service
Factors table on pages 7-9 to the service factor required for
engine driven applications. Service factor recommendations are
minimum. (For extreme shock or high energy loads which must
be absorbed, as when stalling, or for power sources not listed,
consult DODGE for special consideration.)
Steps 1 through 3: Determine service factor, equivalent torque
and required ratio using similar steps from the horsepower
method.
NOTE:
Step 4: Determine Unit Size and Ratio - Refer to torque
tables on pages 66-71. From the high speed shaft rpm in the
left hand column and desired ratio and output rpm in the next
two columns, trace right into the table and find the torque rating
equal to or greater than the required torque calculated above.
Step 5: Check Thermal Ratings - Convert required torque
(without service factor) to horsepower using the formula below.
Check thermal ratings based on the procedure described in the
horsepower method.
Torque (lb-in) x Output Shaft rpm
Horsepower =
63025
AGMA classifies scoop mounted motors as gearmotor applications which are sized using a load classification in place of a service factor. (See Easy Selection Chart, pages 10-23.)
Step 2: Calculate Equivalent Horsepower - Multiply the actual
horsepower to be transmitted by the service factor obtained
from Step 1.
Steps 6 through 8: Refer to horsepower method.
EXAMPLES OF SELECTION
Step 3: Calculate Required Ratio - Divide the high speed shaft
rpm by the low speed shaft rpm.
CAUTION:
Horsepower Method
Instantaneous gear loading is limited to 200% of
the reducer rating. Do not allow starting load or
other peak loads to exceed this value. Failure to
observe this precaution could result in damage to,
or destruction of, the equipment.
A centrifugal pump operating at 230 rpm is driven by a 150
horsepower 1750 rpm motor. The duty cycle is 24 hours per
day. Both the input and output reducer shafts are coupling
connected.
Step 1: Determine Service Factor - Since the centrifugal pump
is operating more than 10+ hours/day, a service factor of 1.25 is
recommended (see page 7).
Step 4: Determine Unit Size and Ratio - Refer to the
horsepower tables on pages 66-71. From the high speed
shaft rpm in the left hand column and desired ratio and low
speed shaft RPM in the next two columns, trace right into the
table and find the horsepower rating equal to or greater than
the equivalent horsepower obtained from Step 2. (When the
required input speed falls between those tabulated, use straight
line interpolation to determine the unit rating.)
Step 2: Calculate Equivalent Horsepower - Multiply the motor
horsepower by the service factor (150 x 1.25 = 187.5) to get the
equivalent horsepower of 187.5.
rpm by the low speed shaft rpm (1750 / 230 = 7.6) to get the
required ratio of 7.6:1.
Step 5: Check Thermal Ratings - Adjust the actual horsepower
required (without service factor) for ambient operating
conditions as described on page 73 to determine actual thermal
HP. Compare the actual thermal HP to the thermal ratings on
pages 74-79. If actual thermal HP exceeds the thermal capacity,
an auxiliary cooling fan or a heat exchanger may be added to
provide additional thermal capacity or a larger reducer may be
selected.
Step 4: Determine Unit Size and Ratio - Locate the
horsepower table for 1750 high speed shaft rpm on page 66.
Trace down the ratio column to the closest nominal ratio to the
7.6:1 required ratio and find 7.59:1 ratio. Trace to the right until
the horsepower equals or exceeds the calculated equivalent
horsepower of 187.5 and find 229 horsepower listed under a
size 70 reducer.
Step 6: Check Overhung and Thrust Loads - Overhung loads
may be imposed on the input or output shafts when connected
by means other than a coupling. If overhung loads are present,
refer to page 80 for method to calculate overhung load. If
calculated OHL exceeds published capacity on page 82, consult
Baldor.
Step 5: Check Thermal Ratings - Calculate actual thermal HP
per the procedure on page 72. Refer to thermal rating tables on
pages 74-79 and find the thermal rating for the size 70 reducer
at 1750 input rpm. Note that the thermal rating without fan is 83
horsepower and the thermal rating with fan is 135 horsepower.
Compare the actual thermal HP to these values to determine if
additional cooling is required.
External thrust loads may exist in applications such as agitators,
mixers and similar equipment. Calculate the direction and
magnitude of the thrust and provide complete application
information to Baldor for review.
Step 6: Check Overhung Load and Thrust Loads - Since both
input and output shafts are coupling connected, overhung or
thrust loads are not applied.
Step 7: Variable Speed Applications - Provide complete
application information to Baldor for engineering review.
Step 7: Variable Speed Applications - Does not apply.
Step 8: Check Dimensions - Refer to pages 24-41 for
dimensions, weights and part numbers.

TORQUE METHOD
Calculate the actual thermal horsepower requirement per
the procedure on page 72. For this example, the ambient
adjustment factors are all considered to be 1.0. Refer to thermal
rating tables on page 76 and find the thermal rating for the
size 70 reducer at 1170 input rpm. Since the 125 calculated
horsepower exceeds the thermal rating shown without fan (91),
an auxiliary cooling fan is required. The size 70 has a thermal
horsepower rating of 137 with fan so this meets the thermal
horsepower requirement.
Running 10 hours a day, a scum breaker for a sewage disposal
system requires 34,233 lb-in of torque at 230 rpm and has an
overhung load of 4,712 pounds on the low speed shaft. The
overhung load is located 4 inches out from the reducer on the
usable shaft extension. The motor speed is 1170 rpm and is
coupling connected.
Step 1: Determine Service Factor - Since the scum breaker is
operating 10 hours/day, a service factor of 1.50 is recommended
(see page 9).
Step 6: Check Overhung Load and Thrust Loads - An
overhung load of 4,712 pounds is on the low speed shaft. It
must be adjusted for its position on the shaft. Refer to page 80
for the load location factor table and locate the 4 inch distance
in the left hand column. Under the MAXUM XTR 70 column find
the load location factor of 1.12. Multiply the 4,712 overhung
load by this factor (4,712 x 1.12 = 5,183) to get an equivalent
overhung load of 5,183 pounds. Now turn to the overhung load
capacity table on page 85 and locate 230 output rpm in the left
hand column. Trace right to the MAXUM XTR size 70 reducer
and find the overhung load capacity of 5,490 pounds. Since the
capacity exceeds the equivalent overhung load, the selection is
acceptable.
Step 2: Calculate Equivalent Torque - Multiply the system
torque of 34,233 by the service factor of 1.50 (34,233 x 1.50 =
51,349) to get 51,349 lb-in equivalent torque.
rpm by the low speed shaft rpm (1170 / 230 = 5.09) to get the
required ratio of 5.09:1.
Step 4: Determine Unit Size and Ratio - Locate the torque
table for 1170 high speed shaft rpm on page 69. Trace down the
ratio column to the closest nominal ratio to the 5.09:1 required
ratio and find 5.06:1 ratio. Trace to the right until the torque
equals or exceeds the calculated equivalent torque of 51,349
and find 57,400 listed under a MAXUM XTR size 70 reducer.
Step 7: Variable Speed Applications - Does not apply.
Step 5: Check Thermal Ratings - Convert the required torque
without service factor (34,233) to horsepower at 230 rpm as
follows:
Horsepower = 34,233 x 230

Thermal rating is the actual horsepower (without service factor) that a drive can continuously transmit without
overheating. The thermal HP shown on pages 74-79 are based on an ambient temperature of 80°F, altitude less than
2,500 feet, an external air flow between 100 and 275 ft per minute, with no direct exposure to sunlight. The thermal
HP is based on providing a maximum calculated sump temperature of 200°F.
If operating conditions do not match the values above, the thermal HP must be adjusted to determine the actual
thermal HP based upon operating conditions. Actual thermal HP equals the published thermal HP multiplied by the
appropriate factors shown below.
Actual Thermal HP = Published Thermal HP x BREF x BA x BD x BV
If the Actual Thermal Horsepower is less than the mechanical horsepower, then a cooling fan or other method needs
to be added to increase the Actual Thermal Horsepower. Failure to consider actual operating conditions may result
in shortened reducer life or catastrophic failure.

OVERHUNG LOAD CALCULATION - Overhung load can be calculated based on the formula below. For applications
where load is proportional to torque (i.e., sheave, sprocket, pinion) an equivalent power (motor power * s.f.) should be
used in the calculation.
OHL(lbs) =
126,000 x hp x Fc x Lf
PD(inches) x rpm
OHL (N) =
19,100,000 x kW x Fc x Lf
PD(mm) x rpm

• Overhung load ratings are for pure radial loads applied one shaft diameter away from the seal carrier and a service factor of 1.0. If overhung load is proportional to torque (i.e., sheave, sprocket, pinion) an
appropriate service factor should be applied (refer to OHL calculation on pages 80-81). Consult Baldor if application has combined radial and thrust loads.

OVERHUNG LOAD CALCULATION - Overhung load can be calculated based on the formula below. For applications
where load is proportional to torque (i.e., sheave, sprocket, pinion) an equivalent power (motor power * s.f.) should be
used in the calculation.
Distance
Distance
OHL(lbs) =
PD(inches) x rpm
OHL (N) =

In order for DODGE to make recommendations on the
required modifications, the following information must be
provided:
DODGE MAXUM XTR Concentric Shaft Reducers can be
modified to permit mounting in positions other than the
conventional (A-1) floor mounting. Some of these include
ceiling (A-3) and wall (A-2 and A-4) and various inclined,
vertical and tilted positions. Consult factory to determine
what modifications are required for your specific
application.
 Reducer Size.
 Ratio.
 Input and/or output speed.
 Transmitted Horsepower.
 Duty cycle. Continuous or intermittent operation. If
intermittent, running time vs. idle time.
 Mounting position, such as A-2, A-3 or A-4 with shafts
level, or a more complete description of the mounting
arrangement including the angle of tilt of the housing,
the incline of the shafts and whether the output shaft is
higher or lower than the input shaft.

General Guidelines for Mounting Variable Speed AC or DC Motors
AMPLITUDE RATIO
DEFINITIONS:
by the small periodic stimulus of the unbalance force
when the motor speed is the same or nearly the same
frequency as the fundamental natural frequency of the
motor and support structure.
FUNDAMENTAL NATURAL FREQUENCY is the
lowest number of times per minute that the motor and
supporting structure will maintain a periodic oscillation,
once displaced, under the sole influence of its own mass
and stiffness.
SOFT MOUNTING - The fundamental natural frequency
is below the motor operating speed.
RESONANCE is a vibration of large amplitude caused
HARD MOUNTING - The fundamental natural frequency
is above the motor operating speed.
88
General Guidelines for Mounting Variable Speed AC or DC Motors
 This motor mount was designed for use with a constant
speed motor at 1750 RPM.
SCOOP MOUNT ACCESSORY
 This is a soft mounting of the motor.
 This accessory is NOT recommended for variable
speed DC or AC applications.
 The benefits obtained by using this accessory are low
cost and isolation of the reducer support structure from
the motor vibration.
NOTE: For more information on DODGE MAXUM XTR
Concentric Reducer Motor Mount, refer to page 59.
 This motor mount was designed for use with a
constant speed motor at 1750 RPM. Use of motors
with lower base speeds increases the chance of
producing resonance. Stiffening techniques within the
scoop structure can increase the fundamental natural
frequency about 20% which is generally enough to
eliminate resonance should it occur.
HD BASEPLATE ACCESSORY
1.This is a hard mounting of the motor.
2.The benefits obtained by using this accessory are:
a. Resonance problems are minimized
 This accessory is NOT recommended for variable
speed DC or AC applications.
b. Accurate assembly of motor/coupling/reducer can be done at the factory instead of the job site.
 Customers who prefer to use the scoop mount
accessory to mount variable speed AC or DC motors
must state on the face of the purchase order that they
plan to support scoop and assume full responsibility for
any vibratory or transient load induced by the motor.
Note: Alignment must always be rechecked at job site prior to start-up.
c. Large motors can be rigidly mounted to keep deflection under control and provide longer service life.
NOTE: For more information on DODGE MAXUM XTR
Concentric Reducer Scoop Mount Reducers, refer to page 46.
3.This accessory is recommended for large motors where
the motor weight exceeds the reducer weight or 700
lbs., and for variable speed DC or AC applications
regardless of the motor weight.
TOP MOUNT ACCESSORY
NOTE: For more information on DODGE MAXUM XTR Concentric Reducer HD Baseplates,
refer to page 60.
 This may be a soft or hard mounting of the motor
depending on the size of the motor and the distance
that the adjusting screws are extended.
 The benefits obtained by using this accessory are low
cost, minimum floor space used for the motor/reducer
assembly, and greater flexibility to obtain the required
output RPM of the reducer than concentric coupling.

Retrofitting Guide to Replace MAXUM with MAXUM XTR - Sizes CR4 through CR6
STEP 1 - Identify MAXUM XTR replacement for the current MAXUM reducer. The replacement size is generally suitable to replace the current MAXUM, however thermal and mechanical ratings should be compared to application requirements to ensure suitability for use. Consult Baldor if the replacement size does not meet application requirements.
STEP 2 - Determine if special output shaft is required. Special output shafts have been designed to match current MAXUM distance from foundation hole to the end of output shaft. Alternatively, the standard MAXUM XTR reducer may be able to replace the current MAXUM using a spacer coupling or an overhung hub on the output shaft extension. Preference should be given to the standard reducer for better cost and availability.
STEP 3 - Identify cooling requirments. Existing cooling devices may not be suitable for the MAXUM XTR.
STEP 4 - Identify motor foundation. MAXUM scoops and motor mounts are suitable for retrofitting to the MAXUM XTR with an additional parts kit. The parts kit listed provides only those parts needed to retrofit. If a completely new scoop or motor mount is desired, order the accessory complete as listed under selection & dimensions tables.

NOTES: 1. The F dimension (see dimensional comparison) of the CR50 is slightly different than the CR4. New foundation holes at the input end will be required.
2. The D dimension (see dimensional comparison) of the CR60 is slightly greater than the CR5. The height of the reducer foundation or the driven equipment must be adjusted to suit.
3. Verify application compatibility and fit of accessories and components.

STEP 1 -Identify MAXUM XTR replacement for the current MAXUM reducer. The replacement size is generally suitable to replace the current MAXUM, however thermal and mechanical ratings should be compared to application requirements to ensure suitability for use. Consult Baldor if the replacement size does not meet application requirements.
STEP 2 - Determine if adapter plate is available. The adapter plate will be bolted to the existing foundation and feature tapped holes for the new Maxum XTR. The difference in foundation hole locations will nominally align the end of the output shaft extension with the existing Maxum drive. Alternatively, the standard MAXUM XTR reducer may be used without adapter plate by adding new holes in the customer’s foundation and shimming the reducer to the appropriate height.
STEP 3 - Identify cooling requirements. Existing cooling devices may not be suitable for the MAXUM XTR.

STEP 2 - Determine if adapter plate is available. The adapter plate will be bolted to the existing foundation and feature tapped holes for the new Maxum XTR. The difference in foundation hole locations will nominally align the end of the output shaft extension with the existing Maxum drive. Alternatively, the standard MAXUM XTR reducer may be used without adapter plate by adding new holes in the customer’s foundation and shimming the reducer to the appropriate height.
STEP 3 - Identify cooling requirements. Existing cooling devices may not be suitable for the MAXUM XTR.
