Figure 10 - Motor Mount Components
Using the hardware provided, assemble uprights (the angled
parts to which the reducer is fastened) to the u-shaped,
rectangular bottom plate. Notice that there are eight slots cut
into the plate. If the reducer is to be mounted in Positions A
or C, as illustrated in Figure 10, assemble the uprights in the
outermost slots. If the reducer is to be mounted in Positions B or
D, assemble the uprights in the innermost slots. The bottom plate
may be mounted with the vertical flanges up or down (as shown
in Figure 10). Snug bolts only, do not torque bolts at this time.
Fasten long threaded studs to the four corners of bottom plate
using jam nuts, one on each side of the plate. Securely tighten
these nuts, as they will not require any further adjustment.
Add one additional jam nut to each stud and thread
approximately to the middle of the stud. Assemble top motor
plate (the flat rectangular plate with many holes) on top of the jam
nuts. Assemble the remaining jam nuts on studs to secure top
motor plate. Do not fully tighten these nuts yet.
The motor mount may be installed in any of the four positions (A,
B, C or D) and in any of the mounting levels (M1, M2, M3 or M4)
shown in Figure 11. Note that the motor mount uprights attach to
the input side of the reducer when mounted in either the "B" or
"D" positions.

Motor Mount Installation
WARNING: To ensure that drive is not unexpectedly started,
turn off and lock out or tag power source before proceeding.
Remove all external loads from drive before removing or
servicing drive or accessories. Failure to observe these
precautions could result in bodily injury.
Remove four or six (as required) housing bolts from the reducer.
Place the motor mount in position and reinstall the bolts through
the motor mount uprights and reducer housing. Where reducer is
shaft mounted in positions A or C, the torque-arm adapter plate
must be mounted between the reducer housing and the motor
mount upright. Tighten bolts to the torque specified in Table 11.
Mount the motor onto the top plate and bolt securely. Install the
motor sheave and reducer sheave as close to the motor and
reducer housings as practical. Loosen the bottom plate bolts
and slide the motor and mounting plate to accurately align the
motor and reducer sheave. Securely tighten the bottom plate
bolts. Install the required number of V-belts and tension belts
by alternately adjusting the jam nuts on the four adjusting studs
provided on the motor mount. Check all bolts to see that they are
securely tightened. Verify that the V-belt drive is properly aligned
before operating the reducer.
