Starter 42.3708-10 – the two-port chetyrekhshchetochny electric motor of a direct current with electromagnetic excitement, the roller coupling of a free wheeling and the dvukhobmotochny traction relay.

In the steel case of a starter four windings of excitement are established. The case and covers of a starter are pulled together with two hairpins. The shaft of an anchor rotates in two bronzografitny plugs established in covers and an intermediate support.

On a shaft of a drive the coupling of a free wheeling (the obgonny coupling) with a driving gear wheel is established. It transfers a torque only in one direction – from a starter to a flywheel, separating them after engine start-up. It is necessary for protection of an anchor of a starter against damage because of excessive frequency of rotation.

The traction relay serves for input of a gear wheel of a drive in gearing with a gear wreath of a flywheel of a cranked shaft of the engine and turning on of the electric motor of a starter. At ignition key turn in the situation "starter" tension moves on both windings of the traction relay (involving and holding). After short circuit of contacts of the traction relay the involving winding is disconnected.

Tension of operation of the relay should be no more than 8 In at 20±5 °C. If it not so, in the relay or a drive is available malfunction. Serviceability of a drive is defined by survey of details after starter dismantling. The faulty relay we replace.
