Remove the engine/transmission assembly from the vehicle, then remove the transaxle from the engine. Make alignment marks on the driveplate and crankshaft to ensure correct alignment during reinstallation. Remove and discard the old bolts securing the driveplate to the crankshaft. If the crankshaft turns, wedge a screwdriver in the ring gear teeth to hold the driveplate. Remove the driveplate from the crankshaft. Be sure to support it while removing the last bolt. Automatic transmission-equipped vehicles have spacers on both sides of the driveplate. Keep them with the driveplate. Installation: Clean the driveplate to remove grease and oil. Inspect the surface for cracks. Check for cracked or broken ring gear teeth. Clean and inspect the mating surfaces of the driveplate and the crankshaft. If the crankshaft rear seal is leaking, replace it before reinstalling the driveplate. Position the driveplate against the crankshaft. Be sure to align the marks made during removal. Note that some engines have an alignment dowel or staggered bolt holes to ensure correct installation. Before installing the new bolts, apply thread-locking compound to the threads. Wedge a screwdriver in the ring gear teeth to keep it from turning, and tighten the bolts to the torque. Follow a criss-cross pattern and work up to the final torque in three or four steps. The remainder of installation is the reverse of removal.
