Inspect clutch disc for wear, cracks, loose rivets, contamination, or excessive run out (warping) and replace if necessary. Measure the depth of the clutch lining at the lining rivets; if the shallowest rivet depth is less than 1 mm (0.04 in), replace the clutch disk. Inspect the flywheel for scoring, hot spots, cracks, or loose or worn guide pins, and replace the flywheel if any faults are found. If the flywheel is removed from the engine, install it using new bolts. Check that the transmission pilot bearing rotates smoothly without play and replace it if faulty. Inspect and clean the release bearing module, checking the release bearing ball stud and spring retainer, replacing them if damaged or worn. Clean the release bearing guide sleeve, ensuring not to grease the release bearing module or guide sleeve, as greasing may cause the release bearing to stick.
