Clutch Assembly: Inspection

Check disc for loose rivets, worn springs or oil contamination. Minimum lining height above rivet heads is .012" (.30 mm). Inspect flywheel and pressure plate for burns, scoring or grooves.
Flywheel and pressure plate runout/warpage limit is .008" (.20 mm). Machine flywheel surface as necessary. Flywheel grinding limit is .020" (.51 mm). If flywheel ring gear is replaced, ensure chamfer on teeth face engine.
Mount clutch disc on input shaft. Check runout using dial indicator. Maximum runout is .04" (1.0 mm). Check disc hub and input shaft splines for excessive wear. Hub must slide smoothly on input shaft splines.
Check pilot bearing for excessive wear. Remove pilot bearing if replacing. Install pilot bearing so that it is recessed .087-.110" (2.18-2.79 mm) below shoulder of crankshaft. Pack bearing with lithium based grease.
