The manufacturer advises the use of new flywheel/driveplate bolts whenever removed. In order to start the process of eliminating a standard flywheel/driveplate, the vehicle is raised and placed safely on jackstands, followed by the transaxle removal. In case of leakages, the front pump seal O-ring of the automatic transaxle or the input shaft seal of the manual transaxle should be replaced. In cars with manual transaxles, disassemble the pressure plate and disc clutch in order to have a chance to inspect or replace the parts of the clutch. Mark the location of the flywheel/ drive plate and crankshaft, so as to use them as an alignment mark when re-assembling. Tear the bolts attaching the flywheel/ driveplate to the crankshaft, jam the flywheel with a screwdriver in case the crankshaft starts to move. The flywheel/driveplate should be carefully pulled off, holding it in place as the final bolt is removed and any spacers used in the automatic transaxle bodies must be retained with the driveplate. With dual-mass flywheels, rotate engine to TDC and fit timing stop, fix flywheel with flywheel-holding tool. Take off the clutch and indicate the association of block with flywheel. Install the flywheel mounting bolts on the flywheel mounting holes and loosen them with a hand tool, but do not touch the openings when loosening or they are likely to be damaged. A flywheel that is dual-mass contains a needle-bearing insert which can be pulled off using a puller and attached using a driver. In models with Multitronic transmission, the damper should be removed in order to access the flywheel bolts. Installation To install, clean the flywheel with brake system cleaner and examine it, looking for damage, and checking it against a straight-edge to see whether it is warped. Wipe and wipe the mating parts of the flywheel/driveplate and crankshaft, and change the crankshaft rear seal in case it is leaky. Place the flywheel/driveplate and spacer on the crankshaft, so that the marks made on removal may be in alignment, and thread locking compound applied to the threads of the bolts before installation. Working up to the full torque in three or four steps, screwdriver Use a screwdriver to hold the flywheel/driveplate stationary as the bolts are tightened in a criss-cross pattern. In the case of cars that have an automatic transaxle, an installed height of the driveplate should be measured at three equal points and shimmed where needed to reach the required height. The rest of the installation goes in the opposite sequence of uninstallation.
