Replacing Poly Chain® Belt
• Remove old belt and replace with new one.
• Replace the belt over the jackshaft sprocket
first. Put the cutter wheel sprocket and the
Poly Chain® belt on the cutter wheel shaft at
the same time, with the sprocket inside the
belt.
• Put the cutter wheel tapered bushing on the
cutter wheel shaft and inside the sprocket.
Push the bushing as close to the position you
marked earlier as possible. Replace and
tighten the screws. Torque screws to 67 ft.
lbs.
• Tighten the belt by sliding the jackshaft
bearings back into the place that you had
marked on the jackshaft plate earlier. If the
old Poly Chain
® belt had the tension
adjusted, you may not be able to get the
bearing to move back to the position marked
earlier. Don’t try to force the bearings back
into that position or you may damage the
new belt.
• Tighten the jam bolts.
