Replacing Jackshaft Bearings
NOTE: To make shaft installation easier, place shaft in a freezer for approximately
one hour or overnight if possible. This will shrink the shaft and make installation
into the new bearings much easier.
Place Poly Chain® sprocket and tapered
bushing back onto jackshaft and tighten
bolts. Replace Poly Chain
® belt. Alignment
is very important, use a straight edge from
the jackshaft sprocket down to the cutter
wheel sprocket to line up sprockets.
After replacing the jackshaft pulley and
bushing, use a straight edge and align the
jackshaft pulley with the engine pulley.
Tighten the three bushing bolts down. As
you tighten the bushing bolts, 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. When replacing
setscrews in bearings, use LocTite
® 242 to
prevent screws from loosening up.
