Cleaning And Inspecting

NOTE: Whenever a part is worn excessively,
cracked, or damaged in any way, replacement is
necessary.
1. Using a 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.
3. Inspect the roller assembly for wear or damage.

NOTE: Flat spots or diameter cannot be less than
23 mm (0.925 in.).
4. Inspect shaft for nicks or burrs.

NOTE: If a spring rate measures less than 10% of
specified load height, it must be replaced.
5. Measure the inside diameter of the movable
sheave bushing. Bushing to shaft clearance must
not exceed 0.25 mm (0.010 in.).

NOTE: If clearance exceeds the limit, the bushing
must be replaced.
Assembling
1. Install the spacer and the movable sheave onto the
driven clutch shaft.
2. Place the retaining ring and spring into the driven
clutch; then place the roller assembly and snap
ring over the spring.
3. Position the roller assembly so the “X” mark is
directly in line with the “X” on the movable
sheave.
