If the gap is not even along the length of the belt, determine
whether the engine is square to the chipper frame. It may
also be that the rotor sheave has moved in or out on the
shaft. Belt alignment can be corrected two different ways:
-
Turning the engine on the mount
-
Adjusting the rotor sheave in or out on the shaft.
Engine Mount Misalignment
After changing the drive belt or loosening the engine mounts, the
belt may become misaligned.

First, make sure the bolts fastening the engine to the mount
are tight. Make sure the engine is square to the base and
the bolts are properly torqued to

.

Twist the engine to one side or the other on the base to
adjust engine position. Recheck belt/sheave alignment.
Repeat as necessary for the best result.
4.
Tighten engine mount bolts. Recheck belt tension and
adjust if required.
Rotor Sheave Misalignment
If the rotor sheave loosens on the shaft, it can become
misaligned with the engine clutch resulting in poor belt
alignment.
