Components of the belt drive of the generator: 1 – bolt of 22 N · m; 2 – bolt of 22 N · m; 3 – tension device for a poliklinovy belt; 4 – bolt of 22 N · m; 5 – generator; 6 – M8 – 22 N · m; M10 – 46 N · m; 7 – adjusting plug; 8 – generator arm; 9 – bolt of 10 N · m; 10 – an arm of the directing roller; 11 – damper of tortional fluctuations; 12 – · m + to tighten a bolt of 22 N on +45 ° (1/8 about.); 13 – the directing roller of a poliklinovy belt; 14 – bolt of 22 N · m; 15 – cap; 16 – poliklinovy belt; 17 – carving plug



Removal
Bring a radiator frame into service situation.

NOTE
Before removal of a poliklinovy belt mark the direction of the course with chalk or a felt-tip pen. Change of the direction of the course of earlier operated belt can lead to its damage.

Turn off the tension screw and take off poliklinovy a belt.

Installation

Fig. 2.394. Contour of a poliklinovy belt: 1 – generator; 2 – poliklinovy belt; 3 – by-pass roller; 4 – damper of tortional fluctuations; 5 – tension roller


Lay poliklinovy a belt in the specified sequence on belt pulleys (fig. 2.394).

NOTE
At installation of a poliklinovy belt you monitor the correct provision on pulleys.


Fig. 2.395. Tension of a poliklinovy belt


Establish a dynamometer key on a hexagon of a tension roller and previously pull poliklinovy a belt the moment of 70 N · m (fig. 2.395).
At the same time twirl the tension screw with the moment of 22 N · m.
Further installation is carried out in the return sequence, at the same time it is necessary observe the following:
– establish a radiator frame by means of Ustanovkany details.
– start the engine and check the belt course.
– lower an emphasis against a provorachivaniye at the expense of a body weight on the rubber buffer and fasten bolts.
– establish a casing of a front bumper.
– check adjustment of headlights.

Inhaling moment
Emphasis of a support of jet thirst for a radiator frame: 28 N · m.
