DRIVE CHAIN AND BELT ALIGNMENT AND
TENSIONING
The chains and belts used on this machine must
be properly aligned and tensioned in order for
the machine to operate properly. Belts out of
alignment do not stay on sheaves and wear or
break more frequently. Sheave alignment can be
checked as described by placing a straightedge
across the sheave faces. Be sure to align and
tension the belts in the order given.
TO ALIGN AND TENSION DRIVE CHAINS AND
BELTS
1. Stop the motor and set the parking brake.
FOR SAFETY: Before Leaving Or
Servicing Machine; Stop On Level
Surface, Set Parking Brake, And Turn

transmission sprocket alignment. If they are
not lined up, loosen the differential bearing
locking collars, align the sprockets, and
tighten the locking collars.

tension. There should be 0.5 in (15 mm)
slack measured midway between the
sprockets. To adjust the tension, loosen the
transmission mounting bolts, slide the
