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 the contact
surface of the weight. The surface 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”.
Bearing Inspection
1. Rotate the clutch bearing in both clockwise and counter-
clockwise directions. The non-braking bearing should
rotate in both directions on the shaft with only a slight
amount of drag.
2. Verify there is no binding or rough spots. If problems are
noted continue with disassembly.
