6.4. Poliklinovy belt

Poliklinova the belt carries out the drive of the generator, the pump of the amplifier of steering, the fan of a radiator, the compressor of the conditioner and the water pump depending on modification of the engine.

Removal
Preventions
Before removal by chalk, a marker or paint note the direction of rotation of a poliklinovy belt. If at installation of the poliklinovy belt which was in the use, it rotates in other party, it will lead to its destruction. Make sure that poliklinovy the belt is correctly located on pulleys.
It is forbidden to open a contour of coolant of the air conditioning system.

Note

Fig. 3.4-24. The units put in action by a poliklinovy belt: 1 – poliklinovy belt; 2 – casing; 3 – bolt, 22 N · m; 4 – bolt, 45 N · m; 5 – bolt, 45 N · m; 6 – generator; 7 – mechanism of a tension of a poliklinovy belt; 8 – bolt, 22 N · m; 9 – a quencher of fluctuations with a pulley of a poliklinovy belt; 10 – bolt, 22 N · m; 11 – nut, 22 N · m; 12 – the aligning plugs; 13 – arm of the compressor of the conditioner and pump of the amplifier of steering; 14 – bolt, 40 N · m; 15 – bolt, 22 N · m; 16 – pump of the amplifier of steering; 17 – adjusting laying; 18 – the aligning plug; 19 – pulley of the pump of the amplifier of steering; 20 – bolt, 22 N · m; 21 – conditioner compressor; 22 – the directing roller of a poliklinovy belt; 23 – bolt, 22 N · m; 24 – a cover of the directing roller


Adjusting laying of 17 (fig. 3.4-24) happens various thickness and serves for adjustment of coaxiality of a pulley and a poliklinovy belt.

Remove a forward cross-piece of a motor compartment.

Weaken a tension of a poliklinovy belt, having turned a key the tension mechanism clockwise (see fig. 3.4-4).

Fig. 3.4-25. Use of a six-sided key for fixing of the mechanism of a tension of a poliklinovy belt in the weakened situation



For fixing of the mechanism of a tension of a poliklinovy belt in the weakened situation insert a six-sided key into the fixing canals (fig. 3.4-25).
Take off poliklinovy a belt and release the mechanism of a tension of a poliklinovy belt.

Installation
Installation is carried out to the sequences, the return to removal, taking into account the following.
Establish poliklinovy a belt at first on a pulley of a bent shaft, then on single pulleys and in the last turn on a pulley of a tension roller.
Launch the engine and check correctness of work of a poliklinovy belt.
Establish a forward cross-piece.
