Withdrawal
1. Jack up the car and put it on stands. Remove the gearbox (see chapter Gear box).
2. On models with manual transmission, remove the clutch assembly (see chapter Clutch and drive shafts). Immediately check the condition of the clutch components and pilot bearing.
3. Turn out bolts of fastening of a flywheel/drive disk to a cranked shaft (see accompanying illustration). If in the process of loosening the bolts the shaft begins to turn, remove the starter (see chapter Engine electrical equipment) and stick a screwdriver between the teeth of the flywheel crown (RKPP), or insert a long drift into one of the holes in the drive plate, resting it against the protrusion on the block (AT). 4. Remove the flywheel/drive plate from the crankshaft.
Note. The flywheel/drive plate is a fairly heavy component - it would be wise to enlist the help of an assistant.
5. Wipe the flywheel thoroughly to remove all traces of oil and grease from it. Check the flywheel running surface for cracks, gouges, clutch friction disc rivet heads, overheating, and burrs. Minor defects can be eliminated with fine-grained sandpaper. Check the ring gear for cracks and chipped teeth. Lay the flywheel on a flat surface in order to assess its flatness (use a flatness meter).
6. Wipe mating surfaces of flywheel/drive plate and crankshaft. If there are signs of oil leakage through the crankshaft rear oil seal, replace it (see Replacement of a back epiploon of a cranked shaft).
Installation
1. Install the flywheel/drive plate onto the crankshaft.
Note. On some motors, a pilot pin is provided, or the mounting holes are arranged asymmetrically, which guarantees a unique fit of the part. Before screwing in the fixing bolts, lubricate the threaded part with a fixing sealant.
2. By blocking the flywheel/drive plate from turning (see paragraph 3), tighten the fixing bolts diagonally to the required torque.
3. Further installation is carried out in the reverse order of dismantling.
