Drive Pulley Installation
A split taper splined bushing is used to locate and
secure drive pulley to belt pulley shaft. This provides an
easy on-off feature.
To remove bushing, remove bolts securing it to pulley
and shaft and place them into threaded bushing holes.
Tighten evenly to press bushing out of pulley.
Clean paint from center pulley hole and insert split
taper bushing into hole. Insert bolts through
unthreaded bushing holes and into threaded holes of
drive pulley, but do not tighten.
Install drive pulley over belt pulley shaft as far as possi-
ble.
Alternately tighten the splined bushing bolts to secure
the drive pulley. Continue to alternate the tightening
sequence until assembly is tight and all bolts are
torqued to 12 ft-lbs.
NOTICE
Be sure to torque bolts to exactly 12 lbs-ft. Do
not overtighten or pulley casting may crack.
