14.1.9. Starter

GENERAL INFORMATION

The internal combustion engine starts a small electric motor – a starter. That in general it was possible to start the engine, the starter should reach speeds of frequency of rotation not less than 300 rpm. It is realizable only if the starter works normally, and the storage battery is rather charged.

The starter consists of a case of 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 normally work more.

In a forward case of a drive the shesterenchaty drive is established. When after ignition inclusion the starter receives tension, 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 limiter on the running screw, it with power short circuit incorporates to a flywheel. Now it is possible to establish a starter of the engine on necessary starting frequency of rotation. If the engine of the car takes dispersal, the gear wheel is accelerated by the engine, therefore, it some time rotates quicker, 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 start of the engine needs high consumption of a current, within maintenance it is necessary to pay attention to irreproachable connection of wires. Clear the correlated connections of wires and grease them with antiacid polar greasing.

Removal

1. Plug 30 wire
2. Plug 50 wire
3. Bolts
4, 6. Holder
5. The holder (only at petrol engines)
7. Spring clip / holder
М1. Starter

PERFORMANCE ORDER
1. Disconnect from the plug of the storage battery a wire (–), a pole connecting it with the car case.
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 appropriate 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 the plug 50 (2) on the traction relay.
4. Remove brackets from 4 to 7 for fixing of wires. At cars with the diesel engine the bracket (5) for fixing 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 starter flange bolts (3).
7. Extend down a starter. At the 6-cylinder engine previously a steering wheel slightly turn to the left.

Installation

PERFORMANCE ORDER
1. Establish a starter and hardly tighten bolts with the moment of 40 N of m. At the 6-cylinder engine again establish a steering for driving directly.
2. Screw a wire on the plug 30 with the moment of 15 N of m, to the plug 50 with the moment of 5 N of m.
3. Establish brackets from 4 to 7 for fixing 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 on hours, and also enter an anticreeping code for radio.
