Clutch: Testing and Inspection
Direct Clutch
FORWARD, DIRECT, INTERMEDIATE, OVERDRIVE AND REVERSE CLUTCHES
1. Inspect clutch cylinder thrust surfaces, piston bore and clutch plate serrations for scores or burrs. Minor scores or burrs may be removed with
crocus cloth. Replace clutch cylinder if badly scored or damaged.
2. Check fluid passage in clutch cylinder for obstructions. Clean out all fluid passages. Inspect bearing surfaces for scores. If excessive clearance or
scores are found, replace output shaft and inspect components.
2. Check splines on output shaft for wear; replace output shaft if splines are excessively worn. Inspect all bushings.
3. Check clutch release spring for distortion and cracks. Replace spring (including wave spring) if distorted or cracked.
4. Inspect composition clutch plates, steel clutch plates and clutch pressure plate for worn or scored bearing surfaces. Replace all parts that are
deeply scored or burred.
5. Check clutch plates for flatness and fit on clutch hub serrations. Discard any plate that does not slide freely on serrations or that is not flat.
6. Check clutch hub thrust surfaces for scores and clutch hub splines for wear.
