Belt (cont.)
•
Next, loosen the two front jam bolts on
the underside of the boom box (one on
each bearing) and move the cutter wheel
toward the engine as far as possible.
This will loosen the Poly Chain® belt.
TIP:
Keep a count of how many turns you
make on the jam bolts when loosening them,
making the same number of turns on both
jam bolts. This makes readjusting the Poly
Chain® belt easier after replacement,
tightening the jam bolts the same number of
turns as you loosened them.
•
Once the belt has been replaced, reverse
the procedure to re-assemble the boom.
Use the jam bolts on the cutter wheel
bearings to adjust proper tension on the
belt making sure to tighten or loosen
them equally, keeping the sprockets
aligned. Use a straight edge to check
sprocket alignment after adjustments
have been made. Refer to the Machine
Maintenance section for how to Check
Belt Tension and Belt Tension
Adjustments for the Poly Chain Belt.
•
Reposition front jam bolts against cutter
wheel bearing and tighten. Readjust the
jam nuts to lock bolt in position.
•
Replace the Poly Chain® belt guard
cover, bottom cover and tighten bolts.
DANGER
Never run machine without all guards in place and secured. Rotating parts are dangerous
and could cause severe injury. Check all bolts for tightness.
