•
Remove old bearings and shaft and replace with
new bearings and shaft. Be sure to turn
jackshaft with the longest keyway pocket
toward the Poly Chain
®
belt side of the boom
and make sure that the locking collars on the
bearings are facing inward. Bolt new bearings
and jackshaft back into place. Just snug bolts
down, do not tighten all the way down, you will
need to move them later to adjust belt tension.
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.
•
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.
