BELT TENSION ADJUSTMENT (cont.)
Procedure for Cutter Poly Chain Belt:
• There are two sets of jam bolts, a FRONT
and REAR on each side of the cutter wheel.
Each set has an outside and inside nut used
to slide the cutter wheel bearing and shaft.
IMPORTANT! Adjust both sides evenly to
ensure proper sprocket alignment.
• To tighten belt tension, loosen the outside
and inside jam nuts on both rear jam bolts.
Then loosen both jam bolts to allow
clearance for bearings to slide. Next, loosen
the two bolts securing each cutter wheel
bearing (both sides). Then, loosen the
outside jam nut on both front jam bolts and
slide the bearing shaft by tightening both
jam bolts equally.
• To loosen belt tension, loosen the two bolts
securing each cutter wheel bearing (both
sides). Next, loosen the inside jam nut on
both front jam bolts then loosen the bolts.
Note: The bearing shaft should move due to
belt tension but if necessary, tightening the
rear jam bolt to slide the shaft.
• Make slight and equal adjustments at a time
and recheck belt tension and sprocket
alignment. Repeat until proper tension and
alignment is achieved.
•
When proper tension and alignment is
achieved, tighten the cutter wheel bearing
bolts and all loose jam nuts.
Never Operate Machine Without Belt Guard Covers in Place and Properly Secured.
Check All Bolts for Tightness.
