The working surface can be machined up to 26.6 mm, but in general not more than 1.5 mm.
In rare cases, damage to the ring gear occurs. If necessary, the ring gear can be removed from the flywheel. To do this, it is necessary to drill a hole between two teeth and cut the remaining jumper with a chisel. A new ring should be heated to 250°C, put on the flywheel and allowed to cool slowly in air. If you do not have experience in performing this kind of work and devices for accurately measuring temperature, it is better to leave this work to specialists. If the crown, when landing on the flywheel, compresses it incorrectly, the crown should be removed, cut it, as described above, and install another new one.
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 dual-plate flywheel with vibration damper. The task of this device is to ensure that the torsional vibrations of the crankshaft, which occur during flashes in the cylinders, are not transmitted to the transmission. Thus, jerks arising from vibrations are extinguished.
The device of a two-disk 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 on 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 of the flywheel becomes elastic.
