The working surface can be processed up to 26.6 mm, but in general no more than 1.5 mm.
In rare cases, damage to the toothed ring occurs. If necessary, the toothed ring can be removed from the flywheel. To do this, drill a hole between two teeth and cut the remaining bridge with a chisel. The new ring should be heated to 250°C, put on the flywheel and allowed to cool slowly in the air. If you do not have experience in this type of work and do not have devices for precise temperature measurement, it is better to leave this work to specialists. If the ring does not press the flywheel correctly when seated on it, the ring should be removed, cut as described above, and another new one installed.
The flywheel can be removed without removing the engine from the vehicle if the gearbox and clutch are removed.
Some models with a manual transmission are equipped with a twin-disc flywheel with a torsional vibration damper. The purpose of this device is to prevent the torsional vibrations of the crankshaft, which occur during cylinder flashes, from being transmitted to the transmission. This dampens the jerks that occur due to vibrations.
The design of a two-disc flywheel is as follows: the front part of the flywheel is rigidly bolted to the crankshaft. A torsional vibration damper is mounted on it, which is a complex system of spring dampers.
The rear part of the flywheel is fixed to this vibration damper, which provides an elastic connection between the two parts of the flywheel. Thus, the connection between the crankshaft and the clutch mounted on the rear part of the flywheel becomes elastic.
