CLUTCHING (PVT)
Roller, Pin, and Thrust Washer Inspection
1. Inspect all rollers, bushings and roller pins by pulling a flat
metal rod across the roller. Turn roller with your finger. If
you notice resistance, galling, or flat spots, replace rollers,
pins and thrust washers in sets of three. Also inspect to see
if roller and bushing are separating. Bushing must fit
tightly in roller. Use the Roller Pin Tool (PN 2870910) to
replace rollers and pins. Take care not to damage roller
bushing or bearing surface of the new pin during
installation.
2. Rubber backed buttons can be used in all clutches if the
hollow roller pin is changed to the solid roller pin.
NOTE: The rubber side of the button is positioned
toward the solid roller pin.
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.
