Motor Mount Installation
3 Loosely install adjusting screws, washers (for flat-head
socket cap screws only) and jam nuts (except #3 and
#7) on to the motor base plate per Figure 1 Do not
tighten adjusting bolts until step 4
NOTE:
If your motor base plate uses two 82 degree
flat-head socket cap screws, make sure to install the
washer between motor base plate and first jam nut as
shown in Figure 1, otherwise motor base plate may
be loose between the flathead cap screw and motor
base plate.
4
ATTACH MOTOR BASE PLATE TO BASE PLATE
SUPPORT
— Install motor base plate onto base
plate support, install jam nuts 3 and 7 per Figure 1
Set motor plate to desired height and torque all jam
nuts per Table 2 After jam nuts are tightened make
sure motor base plate is fully secured to base plate
support
Adjustment of the belt or chain is accomplished
by turning adjusting screws evenly DO NOT over-
tighten belts or chains Over-tightening belts or chains
reduces belt/chain and bearing life When the required
tension is reached, tighten adjusting screw jam nuts
to torques listed in Table 2 Adjust chain tension to
manufacturer’s specifications Adjust belts as follows:
The ideal belt tension is the lowest tension at which
the belt will not slip under peak load conditions Check
belt tension frequently during the first 24 to 48 hours of
run-in operation Keep belts free from foreign material
which may cause slippage Inspect the V-belt drive
periodically; re-tighten belts if they are slipping

MOUNT MOTOR —
Position motor on motor base
plate so that all mounting holes are in alignment Install
and tighten motor fasteners
6
SPROCKET, PULLEY OR SHEAVE CONNECTION —
Mount power take-offs as close to drive and motor
housing as possible to avoid undue bearing load
and shaft deflection Align the high-speed shaft of
drive square and parallel with motor shaft by placing
a straightedge across the face of the sprockets or
sheaves as illustrated in Figure 4 Check horizontal
shaft alignment by placing one leg of a square against
the face of the sheave or sprocket with the spirit level
on the horizontal leg of the square
