• Periodic inspections should be performed. Failure to perform proper maintenance
can result in premature product failure and personal injury.
• All electrical work should be performed by qualied personnel and compliant with
local and national electrical codes.
• Read and follow all instructions carefully.
• Disconnect and lock-out power before installation and maintenance.
Working on or near energized equipment can result in severe injury or death.
• Do not operate equipment without guards in place. Exposed equipment can
result in severe injury or death.
• Never lift the reducer by the input shaft. Lifting lug should only be used to lift the
weight of the reducer. Do not use lifting lug to lift attached assemblies.
• Reducer shipped without oil. Fill to proper level before operation to avoid
damage and/or personal injury. Do not use lubricants with anti-wear/extreme
pressure additives in units with internal backstops - these additives decrease the
backstops’s ability to prevent reverse rotation and will result in backstop failure
which could cause personal injury.

1. Shaft Mount Reducer Installation Instructions
For long service and dependable performance, a shaft mount reducer must be rigidly
supported and accurately aligned. The following instructions are a step-by-step
guide to meeting these requirements for a Browning® TorqTaper Plus shaft mounted
reducer. If there is a need to vary from any of these installation instructions, contact
the Regal Power Transmission Solutions Application Engineering Department at
1-800-626-2093 before completing the installation.
CAUTION: Shaft mounted reducers use bushings to mount the reducer to
various driven shaft sizes. When the driven shaft is smaller than the maximum
bushing size for the reducer, check the driven shaft and key stresses per ANSI/
AGMA Std. 6001-D97 for the application.
1.1 Reducer and Driven Shaft Preparation
1.1.1 The driven shaft diameter is to be within the commercial tolerances for
turned and polished round bars. The key and keyseat in the driven shaft are to be in
accordance with commercial standards for size, depth, offset, lead and parallelism.
1.1.2 The driven shaft on which the reducer is to be mounted must be straight, clean
and free of burrs.
1.1.3 Rotate the driven shaft on which the reducer is to be mounted so the shaft
keyseat is in the upward position.
1.1.4 A lifting lug is provided to lift the reducer into position. The lifting lug may be
repositioned onto any one of the housing ange bolts as required. After repositioning,
all housing ange bolts must be reinstalled to the recommended torque. See bolt
torque specications section.
CAUTION: Do not apply grease, oil or an anti-seize compound to the taper
bore of the reducer, barrel of the bushing, driven shaft or bushing bore. If any of
these substances are applied, equipment failure and personal injury may result.
1.2 DetermineMountingConguration-BushedBoreModels
Due to its unique design, the Browning TorqTaper Plus shaft mounted reducer may be
mounted to a driven shaft in a variety of congurations. The following instructions will
help determine the correct mounting conguration based on the available driven shaft
and key length.
1.2.1 Measure the available driven shaft length “H” (in inches) starting from the end of
the driven shaft to the rst obstruction or point of interference.
1.2.2 Measure the length of the available keyseat “K” in the driven shaft (in inches)
starting from the end of the driven shaft to the end of the usable keyseat.
1.2.3 The following Sections - 1.3, 1.4 and 1.5, show the three standard mounting
congurations for the Browning TorqTaper Plus shaft mounted reducer. Refer to the
following sections in sequence to determine the optimum mounting conguration for the
application.

1.2.4 Using the appropriate reducer size in the Tables 1-3, 1-4 and 1-5, compare
the measured values for H and K to the tabulated values of H and K. If the measured
values for H and K are greater than the tabulated values, the mounting conguration
shown in the gure may be used. If the measured values for H and K are less than the
tabulated values, proceed to the next gure and repeat this step.
Notice: If the measured values for H and K are less than the tabulated values
shown in Table 1-5, contact the Regal Power Transmission Solutions Application

1.6 Installation Instructions Finished Bore Model
1.6.1 The shaft on which the reducer is to be mounted must be straight, clean and free
of burrs. Lubricate the shaft to ease the mounting of the reducer. (Anti-fretting grease
is recommended for nished bore only.) A lifting lug is provided to lift the reducer into
position.
WARNING! Straight bushing kits adapt the gearbox to smaller shafts, which
increases the stress on the shaft and the key. To avoid possible damage to the
gearbox and attached equipment, the driven shaft and key must be designed in
accordance with ANSI/AGMA 6001-D97.
1.6.2 Installation with Finished Bore Bushing Kit
The following items are included with the Finished Bore Bushing Kit:
• One - keyed bushing
• One - plain bushing (no keyways)
• Four - long setscrews
• One - key for connection of keyed bushing to driven shaft
• One - setscrew for holding key to driven shaft
Refer to Figure 1-6A for illustrations of where each of these items are
used.
1.6.2.1 The shaft on which the reducer is to be mounted must be straight, clean and
free of burrs. Lubricate the shaft to ease the mounting of the reducer. (Anti-fretting

2. Lubrication Instructions
Browning TorqTaper Plus reducers are shipped without oil. Before operating, the
reducer must be lled with oil to the proper level to avoid equipment and/or personal
injury. Do not use oils containing EP additives when a backstop is to be used.
Petroleum based mineral lubricants or synthetic lubricants can be used in Browning
TorqTaper Plus reducers. Synthetic lubricants can extend oil change intervals to
as much as 8,000 to 10,000 hours based on operating temperatures and lubricant
contamination. If temperatures vary by season, the oil should be changed to suit the
ambient operating temperature.
Refer to Tables 2-3A and 2-3B to determine proper AGMA viscosity grade oil based
on the reducer’s ambient operating temperature. Contact a lubrication manufacturer’s
representative for assistance in choosing a lubricant.

2.1 Oil Level
2.1.1 Shaft mount reducers require different amounts of oil in the various mounting positions. For the convenience of having enough oil at the installation site, Tables 2-2A and
2-2B show the approximate amounts of oil needed for each common mounting position.
2.1.2 Figures 2-1A and 2-1B show breather, magnetic drain and oil level plug locations for the four standard horizontal mounting positions. Figures 2-2A and 2-2B show breather,
magnetic drain and oil level plug locations for the two standard vertical mounting positions. The breather is installed in the ll hole in the top and the magnetic drain plug is installed
in the bottom of the reducer in its relative position. In the horizontal mounting position use oil level “A” for speeds at or below those shown in Table 2-1. Use oil level “B” for speeds
above those shown in Table 2-1. For reducers mounted in other positions, refer to steps 2.1.4 or, if the reducer is to be installed with the input shaft in the vertical position, refer to
the Vertical Breather Kit instructions.
When Browning TorqTaper Plus reducers operate in areas with a dusty atmosphere, a Filtered Breather Kit is recommended.
Filtered Breather Kit for SMTP 107-800, Browning Part Number 107-800 SMTP FBK.

Notice: TorqTaper seals are grease-packed at assembly. Some purging of grease from around the rotating ingers during initial hours of operation is normal and should be
expected.
WARNING! Reducer shipped without oil. Fill to proper level before operation to avoid damage and/or personal injury. Do not use lubricants with anti-wear/extreme pressure
additives in units with internal backstops - these additives decrease the backstop’s ability to prevent reverse rotation and will result in backstop failure which could cause
personal injury.
Browning TorqTaper Plus reducers may be operated in the horizontal or vertical mounting position
When mounting reducer in the vertical mounting position, a Vertical Breather Kit is required.

2.1.3 To ll reducer with oil, remove the proper oil plug and breather. Fill with oil through the breather hole until oil begins to run out of the oil level hole. Replace the oil level plug
and install breather as shown in Figures 2-1 and 2-2.
CAUTION: Petroleum based and synthetic lubricants which contain anti-wear/extreme pressure additives must not be used in units with internal backstops. These additives
decrease the backstop’s ability to prevent reverse rotation. Consequently, backstop failure will occur.
2.1.4 Operating positions may vary as much as 10° from the four positions shown in Figure 2-1 and still have adequate oil by using the indicated oil levels. If it is necessary to
vary the operating position less than 10° from these positions, complete the following steps. For reducers operating more than 10° from standard position, contact the Regal Power
Transmission Solutions Application Engineering Department at 800-626-2093.
WARNING! See torque arm installation instructions section before releasing the torque arm.
2.1.4.1 Release the torque arm.
2.1.4.2 Rotate the reducer to the nearest of these standard positions.
2.1.4.3 Fill to the proper level.
2.1.4.4 Replace oil level plug.
2.1.4.5 Rotate the reducer back to its operating position and reconnect the torque arm.
Notice: Reducers operating other than standard position should have a stand pipe or sight glass installed and marked at proper oil level in order to monitor oil level while in
operating position. Contact the Regal Power Transmission Solutions Application Engineering Department for assistance in selecting and installing required components.

2.3 Lubricant Selection
2.2 Relubrication Maintenance Schedule
2.2.1 Regularly Scheduled Oil Changes
Refer to Tables 2-3A to determine proper AGMA viscosity grade oil based on the reducer’s ambient operating temperature.
2.2.2 Petroleum Based Mineral Lubricants – Under normal operating conditions oil should be changed every 2,500 hours or six months, whichever occurs rst. If temperatures vary
by season, the oil should be changed to suit the ambient operating temperature.
2.2.3 Synthetic Lubricants – Some types of synthetic lubricants can be used in shaft mount reducers. These lubricants can extend oil change intervals to as much as 8,000 to
10,000 hours based on operating temperatures and lubricant contamination. If temperatures vary by season, the oil should be changed to suit the ambient operating temperature.
CAUTION: Certain mineral oils and synthetics are not compatible. Please contact the lubricant supplier for information regarding lubricant miscibility and proper cleansing
procedures.
WARNING! Petroleum-based and synthetic lubricants which contain anti-wear/extreme pressure additives must not be used in units with internal backstops. These additives
decrease the backstop’s ability to prevent reverse rotation and will result in backstop failure.

3. Hydraulic and C-face Motor Mount Installation Instructions
3.1.1 Before installing the hydraulic motor, measure dimensions A , B, and spline
length (SL) on the hydraulic motor. (See Figure 3-1).
Three conditions must be met:
Condition 1: Dimension A on the motor must be less than the A1 as shown in
Table 3-1.
CAUTION: Failure to meet this condition will damage the hydraulic motor, the
gearbox, or both.
Condition 2:
Dimension B measured from the motor must be less than the B1 value shown in
Table 3-1.
CAUTION: Failure to meet this condition will damage the hydraulic motor, the
gearbox, or both. (Important: Dimension B is to the location where the spline
tooth is full depth see Figure 3-1).
Condition 3:
Subtract spline length (SL) from motor dimension A. The result of this calculation
must be greater than dimension B1 shown in Table 3-1.
CAUTION: Failure to meet this condition reduces the length of spline
engagement and will cause early spline failure.
3.1.2 Lubricate the splined motor shaft with a non-fretting grease. Pre-assemble the
hydraulic motor to the gearbox and hand-tighten the bolts holding the motor. There
must be zero gap between the motor ange and the gearbox ange.
CAUTION: Failure to meet this condition will damage the hydraulic motor, the
gearbox, or both.
3.1.3 Tighten the motor bolts to the torque recommended by the motor’s
manufacturer.
