V-Belt Removal
1. Remove the outer belt cover by removing the
screws and bolts holding it in place. Pull the
middle cover to the left. Take the V-belt off the
pulley.
2. Loosen the pinch bolt of the motor support
casting, raise the motor, and re-tighten pinch bolt.
3. Remove the miter gear from the right
(inboard) side of the transfer rod. Loosen the
shaft collar on the left (outboard) side of the
rod and pull the rod back enough so the V-
belt can be removed. Note the routing of the
old V-belt; now remove the old V-belt and
replace it with the new V-belt.
Machine Reassembly
1. To reassemble the unit after replacing the V-
belt, first place the transfer rod back through the
machine. Tighten the shaft collar. Reinstall the
miter gear on the transfer rod, making sure the set
screw is centered on the flat of the rod.
2. Adjust the tension on the V-belt by sliding the
motor down and then tightening the pinch bolt in
the motor support casting. Adjust so the belt
deflects about 1/2" between the pulleys when
pressed. Excessive tension can increase motor load
and decrease bearing life, while a loose belt can
reduce operating efficiency and shorten belt life.
3. Reinstall the outer and middle belt guard using
the screws and bolts.
4. Make sure that the pulleys are in alignment by
holding a straightedge across their flat sides and
adjusting to it. Also check that all bolts are tight
before using the sander.
