- It is necessary to check periodically a condition of a belt, 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 install the car on supports.
- Note chalk a belt on well foreground.
- Turn the engine for a pulley of a cranked shaft in the direction of rotation before situation at which the cretaceous tag is visible. Thus, a site behind a site examine a belt.
- 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 sites, zapolirovanny to gloss. The belt has to be examined from both parties that means need of its twisting 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 really deep, to replace a belt there is no need.
- The tension of a belt is checked by strong pressing for it by a thumb and definitions of degree of its deflection. Measure the size of a deflection by a ruler. If the distance between centers of pulleys makes from 180 to 280 mm, the size of a deflection has to equal 6 mm. If the distance between centers of pulleys is in limits between 300 and 400 mm, the deflection has to be 13 mm.
- In the presence of one or several of the specified damages maple the belt needs to be replaced new.
|
- Correctly place a belt on pulleys — it has to be strictly on the center of a pulley. Even short-term work of incorrectly established belt can lead to its damage.
