Clutch Assembly: Inspection

Check disc for loose rivets, worn springs or oil contamination. Minimum lining height above rivet heads is .012" (.30 mm). On RX7, minimum disc free thickness is .276" (7 mm) and .327" (8.3 mm) on Pickup models.
Inspect flywheel and pressure plate friction surfaces for burns, scoring or grooves. Friction surface warpage limit is .002" (.05 mm). Resurface or replace flywheel and/or pressure plate as necessary. If flywheel ring gear is replaced, ensure the chamfer on flywheel teeth faces engine.
Mount clutch disc on input shaft. Check runout using dial indicator. Maximum runout is .039" (1 mm). Check disc hub and input shaft splines for excessive wear. Hub must slide smoothly on input shaft splines.
