CLEANING AND INSPECTING
NOTE: Whenever a part is worn excessively,
cracked, or damaged in any way, replacement is
necessary.
1. Using parts-cleaning solvent, wash grease, dirt,
and foreign matter off all components; dry with
compressed air.
2. Remove any drive belt dust accumulation from the
stationary sheave, movable sheave, and bushings
using parts-cleaning solvent only.
! CAUTION
Do not use steel wool or a wire brush to clean
components having a bushing; damage to the
bushing will result.
3. Inspect stationary sheave, movable sheave, spider,
and cover for cracks or imperfections in the
casting.
4. Inspect the cam arm pins for wear or bends.
5. Inspect the bushing in the cover for wear, damage,
or cracks. Measure the inside diameter of the
bushing and the outside diameter of the stationary
sheave hub. The difference (clearance) must be
less than 0.20 mm (0.008 in.). If cover bushing is
not within specifications, replace the cover.
