Fig. 383. A flywheel: 1 — a gear rim; 2 — bolts of fastening of a gear rim; 3 — the adjusting screw (should act on distance a)

The engine flywheel is equipped by a gear rim of the gauge of frequency of rotation of the engine. This gear rim is strengthened on an underside of a cranked shaft by means of three bolts tightened by the moment 10 Н·м. The flywheel kind has already been shown on fig. 383. Pay attention that the inserted adjusting screw should act on 2,5—3,0 mm over a surface (measurement a). For untwisting of bolts of fastening of a flywheel fix its appropriate amount in a motionless condition (for example, having inserted a screw-driver into a gear wreath of a flywheel) and ослабьте flywheel bolts. Flywheel bolts cannot be used repeatedly.

The prevention If the surface of a friction of a flywheel has scratches, such can be, for example at replacement of sliping coupling a flywheel replace.

It is impossible to replace a gear wreath of a flywheel separately from the flywheel. At damage of its teeth it is necessary to replace a flywheel in gathering with a gear wreath. Thus it is necessary to check up and a teeth of a gear wheel of a starter as they too can be worn out.

Bolts are tightened by the moment 60 Н·м, and then turn them for 90 °.
