Roller, Pin and Thrust Washer Inspection
3. 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.
4. Rubber backed buttons can and should be used in
all ATV clutches if the hollow roller pin is changed
to a solid roller pin. NOTE: The rubber side of the
button is positioned toward the solid roller pin. It is
recommended to switch all buttons to the rubber
version during service (if needed).

Teflon bushings are self-lubricating. Do not apply oil
or grease to the bushings .
