Toyota 13405-20010 FLYWHEEL Sub-Assembly

Before removing the driveplate, connect the cable to the negative terminal of the battery and take off the bolt at the negative terminal. Then, unlock transaxle and pull out with transmission case; if there is leakage concern front pump seal or the o-ring ought to be replaced. Also it is advisable to mark the flywheel/driveplate and crankshaft if properly aligned for reassembly as most of the models have eight bolts on the flywheel, it is recommended to use center punch or paint the alignment marks on the driveplate and the crankshaft. The bolts that connect the driveplate and the crankshaft should then be undone and if the crankshaft begins to turn when the driveplate is removed, one can squeeze the latter with the help of a screwdriver that is inserted into the ring gear teeth. Step by slow step, the driveplate should be removed and it should be noted if spacers were used and where they were placed. On installation, check and ascertain whether there are any cracks on the driveplate and for any damaged and broken ring-gear teeth on the flywheel. Scrub the contacting areas of the driveplate and crankshaft, and change the crankshaft rear seal if it seems to be dripping. Mate for the dowels that wee made earlier the position of the dowels in the driveplate must match the position of the crankshaft and then ensure the driveplate is properly placed by either the use of alignment dowels or staggered bolt holes. Coat the thread section of the bolt with thread locking compound in a cross wise manner, gradually building up the torque in stages, usually in three or four turns. The next steps of installation are opposite to the removal steps and include the following.

Specifically, torque specifications should be adhered to, as it is always indicated. On V6 engines, there are two spacers used in driveplate mounting: one is near the crankshaft flange and the other is between the rear face of the driveplate and the driveplate mounting bolts. Before taking out the driveplate, ensure that you label the spacers and make sure that the spacers are put in their respective positions as before and also are facing the right way.

Alignment marks should be made to ensure correct alignment during reinstallation.
