Spider Removal
1. Install clutch in holding fixture and loosen the spider
(counterclockwise) using Clutch Spider Install Tool
(PN 2870341).
NOTE: It is important that the same number and
thickness of washers are reinstalled beneath the
spider during assembly. Be sure to note the number
and thickness of these washers.
2. Inspect the Teflon coating on the moveable sheave
bushing.
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.
