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. 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 weight of the flywheel / drive plate assembly is quite significant - it would be wise to resort to the help of an assistant. Wear work gloves to avoid cutting your hands on the sharp edges of the assembly ring teeth.
5. Wipe the flywheel thoroughly with a rag soaked in acetone, completely removing 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). If necessary, give the assembly to the groove.
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 Section 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 assembly. Before screwing in the mounting bolts, grease their 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 to the dismantling of the components.
