THE GENERAL DATA

The internal combustion engine is started by a small electric motor – a starter. That in general it was possible to start the engine, the starter should be dispersed to frequency of rotation not less than 300 rpm. It is realizable only in the event that the starter works normally, and the storage battery is charged enough.

The starter consists from картера a drive, the case of poles and the collector case. In the case of poles and the collector case the anchor and a collector, and also the holder of coal brushes are established on bearings. In the holder of brushes there are coal brushes which slowly, but constantly wear out. At a high deterioration of coal brushes the starter cannot is more normal work.

In forward картере a drive it is established шестеренчатый a drive. When after inclusion of ignition the starter receives pressure, by means of the traction relay established on the case of a starter, the gear wheel is displaced on an abrupt carving to a gear rim of a flywheel of the engine. As soon as the gear wheel reaches the terminator on the running screw, it with power short circuit incorporates to a flywheel. Now the engine starter can be established on necessary starting frequency of rotation. If the car engine takes dispersal, the gear wheel is accelerated by the engine, hence, it some time rotates faster, than the engine of a starter and leaves gearing thanks to what connection of a gear wheel with an internal combustion engine is liquidated. As for engine start high consumption of a current within the limits of maintenance service it is necessary to pay attention to irreproachable connection of wires is required. Clear the correlated connections of wires and grease them противокислотной with polar greasing.

Removal

1. A wire of the plug 30
2. A wire of the plug 50
3. Bolts
4, 6. The holder
5. The holder (only at petrol engines)
7. A spring clip / the holder
М1. A starter

PERFORMANCE ORDER
1. Disconnect from the plug of the storage battery a wire (–), a pole connecting it with the car case.
The prevention

Disconnect this wire from the battery only at the switched off ignition, the actuation device of system of injection of fuel otherwise can be damaged. Before a detachment of wires from plugs of the storage battery it is necessary to read also recommendations in corresponding section.


2. Raise the car ahead. If is available, remove the bottom cover of a motor compartment.
3. Disconnect a wire from the plug 30 (1) and plugs 50 (2) on the traction relay.
4. Remove скобы from 4 to 7 for fastening of wires. At cars with the diesel engine скоба (5) for fastening of wires is absent.
5. The 6-cylinder engine with an automatic transmission: unscrew on a frame the back bearing of a shaft of the engine.
6. Unscrew on a flange of a starter bolts (3).
7. Extend downwards a starter. At the 6-cylinder engine preliminary a steering wheel slightly turn to the left.

Installation

PERFORMANCE ORDER
1. Establish a starter and hardly tighten bolts with the moment 40 Н.м. At the 6-cylinder engine again establish a steering for driving directly.
2. Screw a wire on the plug 30 with the moment 15 Н.м., to the plug 50 with the moment 5 Н.м.
3. Establish скобы from 4 to 7 for fastening of wires.
4. Establish the bottom cover of a motor compartment.
5. Connect to the plug of the storage battery a weight wire (–). Establish time for hours, and also enter an anticreeping code for radio.
