First, in order to affect the removal of the engine/transaxle assembly, the transaxle should be separated from the engine. Should a manual transaxle be present, first and foremost the pressure plate and the clutch disc should be taken off. Scribe alignment marks between the flywheel/driveplate and crankshaft so you can properly align the items the next time you will install them. Subsequently, undo the bolts fixing the flywheel/driveplate to the crankshaft and pull out the flywheel/driveplate. For installation, before assembling the flywheel clean it with spirit accountable to remove the grease and oils employed before for lubrication; the flywheel should not possess any crack, rivet grooves, burned area, or any score marks but in case of the later two, light scoring can be eradicated using emery cloth. Look for the crack or breakage of the ring-gear teeth and also the flatness of the flywheel, if it is warped or not. Mate, clean, and inspect flywheel/drive plate and crankshaft surfaces, replace the crankshaft rear seal if it is leaking. Locate the flywheel/driveplate against the crankshaft and if there's a spacer, put it in before lining up the marks that you have already made. Place a lock-tight thread-locking compound on the bolt's threading before its installation. This could be done with the use of a screwdriver to ease the process of tightening the bolts where the flywheel/driveplate will not turn until all the bolts are tightened in a scribe cross-hatch method until the final torque is attained. The other procedures of installation are executed with the opposite sequence of operations for removal and, at last, join the battery and carry out the required re-learn activities.
