Removing
1. Jack up the car and put it on stands. Remove transmission (see chapter Transmission).
Attention! The engine should be hung from above on a winch or beam.
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. On AT models, this would be a good time to check the condition and replace the front oil seal/pump o-ring.
4. With a marker or paint, mark the position of the flywheel / drive plate relative to the end of the crankshaft.
5. Turn out bolts of fastening of a flywheel/drive disk to a cranked shaft. If the shaft begins to turn while loosening the bolts, jam a screwdriver or pry bar between the teeth of the flywheel ring (RKPP), or insert a long drift into one of the holes in the drive plate, resting it against the protrusion on the block (AT).
6. 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.
7. 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.
8. Wipe mating surfaces of flywheel/drive plate and crankshaft. If there are signs of oil leaks developing 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 disk on the crankshaft, - make sure that the landing marks applied during the dismantling of the assembly are aligned correctly.
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. After blocking the flywheel/drive plate from turning, tighten the new mounting bolts diagonally to the required torque.
Note. The flywheel/drive plate mounting bolts must be replaced without fail.
3. Further installation is carried out in the reverse order to the dismantling of the components.
