The maker suggests that when removing the flywheel/driveplate bolts, one should replace them with fresh ones. The first thing to do is to lift up the vehicle to place it squarely on jackstands, after which the transaxle is taken out. In the event of any leaks, it is recommended to change the front pump seal/O-ring of automatic transaxles or input shaft seal of manual transaxles now. In manual transaxle vehicles, the pressure plate and the clutch disc should be removed and a person should take the chance to check or replace the clutch components. Make alignment marks on the flywheel/driveplate and crankshaft with a center punch or paint to be sure that they align on the right spot when reinstating. Then loosen the bolts holding the flywheel/driveplate to the crankshaft, carefully so as not to damage the crankshaft thread; furthermore, the crankshaft turns, so you can wedge a screwdriver in the ring gear teeth to hold the flywheel. Be careful when removing the flywheel/driveplate off the crankshaft, supporting it throughout the last bolt removal process and ensuring that spacers on either side of the driveplate which are provided with an auto transaxle fitted car are retained with the driveplate. To install, clean the flywheel, grease, and oil off, checking the surface, cracks, rivet grooves, burnt, and score marks, and light scoring can be cleaned up with emery cloth. Inspect cracked and broken teeth of ring gears, the flywheel being placed on a flat surface to test it by a straightedge whether it warps. Wipe and examine the mating surfaces of the flywheel/driveplate and crankshaft and change the crankshaft rear seal in case it is leaking and reload the flywheel/driveplate. Install the flywheel/driveplate and spacer to fit against the crankshaft and align it with the marks left as a guide during removal and note that certain engines have an alignment dowel or staggered bolt holes to be installed correctly. Put thread locking compound on the threads of the bolts, then engage a screwdriver in the teeth of the ring gear, so as not to turn the gear, and screw the bolts in a criss-cross manner stepping up to the full torque of 3 or four steps. In vehicles that have automatic transaxles, measure the installed height at three different points around the driveplate and then take an average reading; in case it is wrong then the driveplate would have to be taken out and shimmed to a correct size. Other parts of the installation are the opposite of the uninstallation process.
