CLEANING AND INSPECTING
1. Using parts-cleaning solvent, wash grease, drive belt
dust, and foreign matter off all components.
2. Inspect the rollers for damage, cracks, or wear.
3. Inspect the sheaves for any gouges, cracks, or other
damage. Also, inspect threaded areas of sheaves for
damaged or stripped threads.
4. Inspect the back-side cams and torque bracket for
cracks or damage. The ramp portions of the bracket
must be free of gouges and damage. Minor scratches
may be repaired using #320 grit wet-or-dry sandpa-
per.
5. Inspect spring for distortion, crystallization, or
breaks.

Movable Sheave Bearing Tool.
! WARNING
Never operate the engine without the belt guard/access
panel secured.
CAUTION
Do not use steel wool or a wire brush to clean driven
clutch components. A wire brush or steel wool will
cause the sheaves to be gouged (thus, the drive belt
may not slide properly between sheaves). Decreased
performance and possible accelerated drive belt wear
will result.
