adjustment after the first 50 hours of operation,
thereafter; every 200 hours. Adjust if required.
Important
Mis–adjusted clutches will slip and generate
excessive heat (blueing) resulting in failure.
1. To adjust clutch, tighten or loosen locknuts on
flange studs.
2. Check adjustment by inserting feeler gauge thru
slots next to flange studs.
3. The proper disengaged clearance between the
clutch plates is .011 – .021 inches. It will be necessary to
check this clearance at each of the three slots to ensure
the plates are parallel to each other.

spindle is loose inside the bushings, bushings are worn
and must be replaced.
