Replacing Jackshaft Bearings
• Using a straight edge, align the engine
pulley with the jackshaft pulley and
place bushing in and tighten the three
bolts down. As you tighten the
bushing, make sure that the pulleys
stay aligned.
• There are two setscrews in each bearing.
Tighten one of them down, remove one,
and punch a start point in the shaft to
drill a 5/16” diameter hole just deep
enough for the screw to enter the shaft.
Do this for all four setscrews. This will
help prevent shaft from spinning inside
of bearing. Use LocTite® 242, when
tightening setscrews in bearings, to
prevent screws from loosening up.
NOTE: Refer to SERVICING BELTS section for proper installation and tensioning of all belts.
• Replace V-belt and Poly Chain
® belt
guards.
DO NOT RUN MACHINE WITHOUT
ALL GUARDS IN PLACE AND
SECURED.
