 PERFORMANCE ORDER

  1. It is necessary to check periodically a condition of a belt, and at detection of defects, to replace a belt.
  2. The tension of a belt is carried out by an automatic natyazhitel and does not need check.
  3. Switch off the engine, establish transmission in neutral situation. Lift and install the car on supports.
  4. Note chalk a belt on well foreground.
  5. Turn the engine for a pulley of a bent shaft in the direction of rotation to situation at which the cretaceous tag is visible. At the same time, the site behind the site examine 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 sites, zapolirovanny to gloss. The belt has to be examined on both sides that means need of its twisting for check of a condition of inner 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.
  7. 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, then 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.
  8. In the presence of one or several of the specified damages maple the belt needs to be replaced new.
  1. 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.
