Replacing Poly Chain® Belt
• Loosen, do not remove, the nuts on the bolts
that are holding the belt guard to the
machine.
• Loosen Poly Chain® belt by moving
jackshaft bearings back toward rear of
machine. MARK THEM SO THAT YOU
KNOW HOW THEY ARE
POSITIONED ON THE JACKSHAFT
PLATE. Loosen, do not remove, the four
bolts that hold the jackshaft bearings down.
• Loosen the jam bolts in the back and move
the bearings toward cutter wheel.
• Place a mark on the cutter wheel shaft
next to the cutter wheel bushing for
replacing the bushing and sprocket.
• When the belt has been loosened, remove
the cutter wheel sprocket. Remove the three
screws in the bushing and then screw two of
the screws into the two threaded holes to
push the bushing out of the sprocket. Turn
one screw a small amount and then turn the
other screw the same amount to keep from
damaging the bushing or sprocket, work
back and forth until the sprocket is loose.
• You may have to strike the sprocket rim
with a dead blow hammer or leather mallet,
NOT A STEEL HAMMER, while applying
tension with the two screws to break
sprocket loose.
