Button To Tower Clearance Inspection
1. Inspect for any clearance between spider button to
tower. If clearance exists, replace all buttons and
inspect surface of towers. See “Spider Removal”
procedure.
2. Inspect sheave surfaces. Replace the entire clutch if
worn, damaged or cracked.
Shift Weight Inspection
1. If clutch is not disassembled, inspect as shown, using
a clutch holding tool to compress the moveable
sheave. The contact surface of the weight should be
smooth and free of dents or gall marks.
2. Remove shift weight bolts and weights. Inspect as
shown. The contact surface of the weight should be
smooth and free of dents or gall marks. Inspect the
weight pivot bore and pivot bolts for wear or galling. If
weights or bolts are worn or broken, replace in sets of
three with new bolts.
NOTE: A damaged shift weight is usually caused by
a damaged or stuck roller in the spider assembly.
See “Roller, Pin and Thrust Washer Inspection”.
