Clutch Disassembly
1. Using a permanent marker, mark the cover, spider, and
moveable and stationary sheaves for reference, as the cast
in X's may not have been in alignment before disassembly.
2. Mark the stationary sheave and clutch shaft to verify the
shaft has not turned in the sheave after tightening the spider
during clutch assembly.
3. Remove cover bolts evenly in a cross pattern and remove
cover plate.
4. Inspect cover bushing (A). The outer cover bushing is
manufactured with a Teflon
coating. Wear is determined
by the amount of Teflon
remaining on the bushing.
5. Inspect area on shaft where bushing rides for wear, galling,
nicks, or scratches. Replace clutch assembly if worn or
damaged.
6. Remove and inspect the clutch spring. See “Drive Clutch
Spring Specifications” for spring inspection.

loosen the spider (counterclockwise) using Clutch Spider
Removal Tool (PN 2870341).
Cover Bushing Inspection:
Replace the cover bushing if more
brass than Teflon
is visible on
the bushing. Refer to bushing
replacement in this chapter.
