To remove the manual transmission, one should matchmark the clutch cover and flywheel for reinstallation. Removing the flywheel involves unscrewing the bolts which are spaced unevenly. To replace a ring gear, bore a hole between two teeth and then split it using a cold chisel. To install a new gear, first polish areas on the ring, heat it until the polished spots turn blue, and place it on the flywheel shoulder. Subsequently, allow ring to cool and collapse back into place. The flywheel must be free of burrs as well as crankshaft flange before installation of flywheel commences. For automatic transmission removal, first detach the transmission and then remove six bolts that attach flywheel to crankshaft flange. In this regard, while inspecting a flywheel for cracks, wear or broken teeth also check for burrs on crankshaft flange and flywheel). Install the flywheel in its correct position with irregularly spaced bolt holes; thereafter torque bolts to specification. Check runout on the face of the flywheel using dial indicator; high side should be tapped with a mallet if necessary. If runout is beyond limit, remove the wheel again checking for burrs between it and crankshaft mounting flange.

First, you will need to raise the vehicle and support it securely on jackstands, then remove the transaxle. This is an opportune time for those vehicles with automatic transaxle to replace their front pump seals/o-rings if they are leaking. On vehicles fitted with manual transaxle, you will have to remove the pressure plate and clutch disc. The clutch components and pilot bearing can also be checked or replaced at this point. If there is no dowel pin, this means that you have to make some marks on both the flywheel/driveplate and crankshaft so as not to miss alignment during reinstallation. You must remove bolts that attach the flywheel/driveplate to the crankshaft. Insert a screwdriver between the drive plate holes of automatic transmissions or fix it against teeth of a ring gear on flywheel for manual transmissions in case that crankshaft tries turning. When removing one last bolt, ensure that you hold up the tentatively heavy flywheel properly. Get off from the engine's crankshaft by pulling out driveplate/flywheel assembly from it; pay attention and do not put them somewhere around! The grease and oil needs removal so clean up your flywheel thoroughly well before inspecting its friction surfaces where cracks burns rivet grooves score marks should be spotted easily enough among light scoring which might be polished off using emery cloth if any exists besides check out whether your ring gear has cracked or broken teeth while checking flatness of a surface under it's bottom edge Make sure that both faces are smooth even though they may look rough due to accumulated dust dirt etc.; sometimes when installing new rear oil seals never forget about putting some grease onto them prior their installation instead position properly against dowels or previously drawn marks if applied aligning fly wheel into correct place during disassembly stage use thread locker when applying nuts complete everything described above tightening way too much could make heads get loose in reverse order of course.
