ASSEMBLE SUPPORT BRACKET TO MOTOR
MOUNT BRACKET
— Use the fasteners provided .
Refer to Table 1 for fastener size and tightening torque .
4 .
ASSEMBLE BASE PLATE TO MOTOR MOUNT
BRACKET (FIGURE 1)
— Assemble adjusting screws
to motor mount bracket and base plate with jam nuts
above and below the base plate .
5 .
MOUNT MOTOR
— Position motor on base plate so
that all mounting holes are in alignment . Install and
tighten motor fasteners .
6 .
SPROCKET, PULLEY OR SHEAVE CONNECTION
— Mount power takeoffs 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 . 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 .
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 1 . Adjust chain tension to manufacturers’
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; retighten belts if they are slipping .
