 PERFORMANCE ORDER

1. The tension of a ridge belt is made automatically. It is necessary to check periodically a belt condition, and at detection of defects, to replace a belt.
2. The tension of a belt is carried out by an automatic natyazhitel and check does not need.
3. Switch off the engine, establish transmission in neutral situation. Lift and establish the car on supports.
4. Mark chalk a belt on well foreground.
5. A head turn the engine for a pulley of a cranked shaft in the rotation direction, i.e. to the right side so that cretaceous marking was visible. Thus a site behind a site see a belt.
6. Fingers (and using a small lamp if it is necessary) walk on all length of a belt, feeling on existence of cracks and stratifications. Also check, whether is not present on a belt of attritions and zapolirovanny sites to shine. The belt should be examined from both parties that means need of its perekruchivaniye for check of a condition of seamy side. Be in passing convinced of lack of a rust, cracks and agnails on pulleys. On a working surface of a belt existence of superficial perpendicular cracks is allowed. If these cracks do not overstep the bounds of one edge and not so deep, to replace a belt there is no need.

Separation of edges of J, K crack

7. The tension of a belt is checked by strong pressing on it by a thumb and definitions of degree of its deflection. Size of a deflection measure by a ruler. If the distance between centers pulleys makes from 180 to 280 mm, the size of a deflection should equal 6 mm. If the distance between centers pulleys is in limits between 300 and 400 mm, the deflection should be 13 mm.
8. In the presence of one or several of the specified damages maple it is necessary to replace a belt with the new.

9. Correctly place a belt on pulleys. Even short-term work of incorrectly established belt can lead to its damage.
