3.3. A poliklinovoj beltThe poliklinovoj belt carries out a drive of the generator, the pump of the amplifier of a steering, the fan of a radiator, the compressor of the conditioner and the water pump depending on engine updating.
Removal
At removal semi wedge a belt it is necessary to consider the following.

1. At removal and installation of a pulley 13 (a Fig. 3.1–39) for its fixing from проворачивания it is necessary to use the special tool 3212.
2. At installation it is necessary to use a new sealing ring 16.
3. Categorically it is forbidden to unscrew and separate pipelines for a coolant.
4. At removal of the engine the compressor is necessary for moving 22 conditioners aside together with the pipelines connected to it with a coolant and to fix it on a body a soft wire.
5. Installation of a pulley 24 is possible only in one position.
Disconnect a wire of "weight" from the storage battery.
Unscrew a casing of the fan of a radiator and remove it.

Fig. 3.1–40. A reversing of a bolt of fastening of the fan of a radiator
|
Keeping a pulley of the fan of a radiator from проворачивания a special key 3212, a usual key unscrew a bolt of fastening of a pulley. As the bolt has the left carving, for unscrewing it is necessary to rotate it clockwise (fig. 3.1–40).
Lift upwards the fan of a radiator and remove it from the car.

|
Fig. 3.1–42. An arrangement of collars of fastening of an air branch pipe of a flowmeter of air and the soaking up pipeline: 1 – the pipeline of giving of fuel; 2 – a hose of giving of fuel
|
Loosen the the collars shown by arrows on fig. 3.1–42, also remove the air branch pipe which is connecting a measuring instrument of the expense of air and soaking up the pipeline.

|
Turn out screws and remove a casing semi wedge a belt (fig. 3.1–43).
The prevention
Chalk, marker or paint note a rotation direction semi wedge a belt. If at installation полиwedge the belt rotates in other party, it will lead to its destruction.

Fig. 3.1–44. Tension easing semi wedge a belt: 1, 2 – installation sites of pins for fixing of the mechanism of a tension. By an arrow the rotation direction шестигранного a key for tension reduction semi wedge a belt is shown
|
Using face шестигранный a key on 10 mm, loosen the a tension semi wedge a belt, having turned the tension mechanism clockwise before combination of apertures 1 and 2 (fig. 3.1–44).
Fix the tension mechanism in this position, having inserted into an aperture a steel core in diameter of 5 mm.
Remove полиwedge a belt from pulleys.
Installation
Put on driving a belt, operating in a direction counter-clockwise, at first on a pulley of a cranked shaft, and then and on a tension roller.

An arrangement semi wedge a belt on pulleys of cars with the fan with вязкостной муфтой and the conditioner: 1 – the generator; 2 – полиwedge a belt; 3 – the pump of the amplifier of a steering; 4 – the fan with вязкостной муфтой; 5 – the conditioner compressor; 6 – a cranked shaft; 7 – a tension roller
|
Take out the steel core fixing the mechanism of a tension.
Establish a pulley of the fan of a radiator and fix its nut, having tightened its moment 37 Нм.
The prevention
The nut of fastening of a pulley of the fan of a radiator has the left carving, therefore to tighten it it is necessary turn counter-clockwise.
Start up the engine, check up correctness and uniformity of moving semi wedge a belt.
