3.11. Check of a condition of multicostal belts of a drive of auxiliary unitsCheck of a belt of a drive of auxiliary units
|
Establishing a driving belt, correctly place it on pulleys (strictly on the center). Even short-term functioning of incorrectly established belt can lead to its damage! |
|
- Schemes of laying of a belt of a streaming drive of auxiliary units are presented in the Section Replacement of a belt of a drive of auxiliary units and elements of the mechanism of its tension.
- Fingers (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.
- Adjustment of a tension of a driving belt is made automatically. It is necessary to check periodically a belt condition, and at detection of defects, to replace a belt.
- The tension of a belt is carried out by an automatic natyazhitel and check does not need.
- Switch off the engine, establish transmission in neutral situation. Lift and establish the car on supports.
- Mark chalk a belt on well foreground.
- Face key turn the engine for a bolt of a pulley of a cranked shaft in the direction of normal rotation (clockwise) until again there will be no cretaceous marking, - attentively study a condition of a tape of a belt on all its length.
- The tension of a belt can be checked by a way of strong pressing on it a thumb and definitions of degree of its deflection. Size of a deflection measure by a ruler. At distance between centers pulleys from 180 to 280 mm the size of a deflection of a belt should equal 6 mm. If the distance between centers pulleys is in limits between 300 and 400 mm, the deflection should be 13 mm.
- In the presence of one or several of the specified damages it is necessary to replace a belt (see. Head Engine).
- Make sure of correctness of landing of a belt on pulleys.
