Lexus 32101-48010 Gear Sub-Assy, Drive Plate & Ring

Start by removing the leaking front pump seal or O-ring, then take off the pressure plate and clutch disc. Check or replace clutch components as needed. Mark the flywheel, drive plate, and crankshaft for reinstallation. Remove the bolts securing the flywheel or drive plate to the crankshaft. Remove the flywheel or drive plate, supporting it while removing the last bolt. Align the marks made during removal, apply thread-locking compound to the bolts, and secure them in a crisscross pattern. Installation is the reverse of the removal.

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.

To completely withdraw the engine/transmission assembly from the car first, it is required to separate the transaxle from the engine. Mark the key ways of the driveplate and crankshaft so it will align properly when it is reinstalled. Remove the old bolts that clamps down the driveplate over the crankshaft, and, if a crankshaft rotates, put a screwdriver under the driveplate to prevent if from turning. Be very slow in the process of pulling out the driveplate and support it while removing the last bolt on the puller, and note that the vehicle automatic transmission has spacers on each side of the driveplate. Regarding the 2GR-FKS engines, understand the crankshaft angle sensor plate and beveled edge washer. Iwash the driveplate in order to remove all chances of grease and oily films, after that I look for cracks on the driveplate and check the condition of the ring gear teeth. Replace the rear crankshaft seal if it comes with one and check and clean the mating surface for the drive-plate and crankshaft. On 2GR-FKS engines, bolt the crankshaft angle sensor plate followed by the proper orientation of the same before the fitting of the driveplate and spacer. Insert the driveplate onto the crankshaft by placing the marks made during the removal of the component back into place if there are alignment dowels or using the staggered bolt holes, in case there are any, to ensure installation of driveplate is correct. Put a thread-locking compound on new bolts and tighten and lock them interlacely in a gradual manner to the final torque magnitude. The subsequent steps of installation procedure are contrary to the removal steps of flash application.

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.
