Raise the vehicle and support it securely on jackstands, then remove the pressure plate assembly and clutch disc. Use paint to make an alignment mark from the flywheel to the end of the crankshaft for reinstallation purposes. Remove the bolts securing the flywheel to the crankshaft rear flange; if difficulty arises due to crankshaft movement, wedge a screwdriver through the starter assembly opening to prevent the flywheel from turning. After removing the flywheel, clean any grease or oil from its surface and inspect for rivet grooves, burned areas, or scoring, correcting light scoring with emery cloth. Check for cracked or broken teeth and lay the flywheel on a flat surface to check for warpage. Clean the mating surfaces of the flywheel and crankshaft, then position the flywheel against the crankshaft, aligning it with the marks made during removal. Before installing the retaining bolts, apply a dab of sealing agent on the threads and tighten the bolts finger tight. Wedge a screwdriver through the starter motor opening to keep the flywheel from turning while tightening the bolts, and complete the installation by reversing the removal procedures.
