Cleaning and Inspection
CLEANING
Clean the clutch components with solvent and dry them with compressed air. Do not use rags or shop towels to dry any of the clutch parts. Lint from
such materials will adhere to component surfaces and could restrict or block fluid passages after assembly.
INSPECTION
Replace the clutch discs if warped, worn, scored, burned/charred, the lugs are damaged, or if the facing is Raking off. Replace the top and bottom
pressure plates if scored, warped, or cracked. Be sure the driving lugs on the pressure and clutch plates are also in good condition. The lugs must not
be bent, cracked or damaged in any way.
Replace the piston spring and wave spring if either part is distorted, warped or broken.
Check the lug grooves in the clutch retainer. The clutch and pressure plates should slide freely in the slots. Replace the retainer if the grooves are worn
or damaged. Also check action of the check balls in the retainer and piston. Each check ball must move freely and not stick.
Replace the retainer bushing if worn, scored, or doubt exists about bushing condition.
Inspect the piston and retainer seal surfaces for nicks or scratches. Minor scratches can be removed with crocus cloth. However, replace the piston
and/or retainer if the seal surfaces are seriously scored.
Check condition of the fiber thrust washer and metal output shaft thrust washer. Replace either washer if worn or damaged.
