THE GENERAL DATA

Klinovoj belt (standard design)

1. A tension roller
2. A remennyj pulley of a cranked shaft
5. A remennyj pulley of the generator of a three-phase current
7. A remennyj pulley of the pump of the amplifier of a steering
8. A remennyj pulley of the pump of a cooling liquid

The klinovym belt puts in action all additional units of the engine. Ridge клиновой the belt is wider, than usual клиновой the belt and has many edges on an inside. Ridge клиновой the belt stretches by means of the automatic pulling device consisting of a spring of a stretching, a tension roller and the shock-absorber. The shock-absorber provides a uniform tension of a belt in all range of turns of the engine. Depending on the car equipment клиновой the belt has various length.

Removal


PERFORMANCE ORDER
1. Remove hydraulic муфту the fan.

The prevention

The nakidnaja nut has the left carving.


2. Release pulling device, turn off a nut with a fillet (378).
3. Insert into an aperture of the lever of a tension of a spring (374) core and press it against effort of a spring of a stretching (380) to the left (in a direction маслоизмерительного щупа) while the bolt (375) will not unload so that it can be pushed out in a direction of an inlet pipe. As a core it is possible to use a wrench from the onboard tool of the car or the lever in length about 300 mm and diameter 12–13 mm.
4. Slowly release the lever of a tension of a spring, wring out a tension roller and remove клиновой a belt.

Installation

PERFORMANCE ORDER
1. Check up profiles of belt pulleys on absence of damages and pollution if it is necessary, clean or replace pulleys. Thus pay attention on лунки in belt pulleys and the loosened places of fastening of the pulling device.
2. At presence лунок on a pulley replace it. Replace also the tension device if fastening support are loosened.
3. Ridge клиновые the belts having pollution between ledges of edges, belts with cross-section cracks and the broken edges necessarily replace.
4. Slightly raise a tension roller, turn a belt from the back party so that the small loop was formed, and push it between belt pulleys of the pump of a cooling liquid and a cranked shaft.
5. Strong press ridge клиновой a belt to a belt pulley of the pump of a cooling liquid and simultaneously turn ременный a pulley to the left (marksman) while the belt will not appear on a tension roller.

6. Impose клиновой a ridge belt on a tension roller and ременный a pulley of a cranked shaft. Then, turning a free part of a belt, impose it on belt pulleys of the cooling compressor, the pump of the amplifier of a steering, the pump of a cooling liquid and the generator of a three-phase current.

7. By means of a core (1) turn to the left the lever of a tension of a spring (2) while it will allow a bolt (3). So the belt tension is carried out. (4 – a stretching spring)
8. Tighten a nut with a fillet (1).

9. Check durability of landing клинового a ridge belt on belt pulleys.

10. Establish hydraulic муфту the fan.
