 PERFORMANCE ORDER

  1. 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.
  2. 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.
  3. 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.
  4. The tension of a belt is carried out by an automatic natyazhitel and check does not need.
  5. Switch off the engine, establish transmission in neutral situation. Lift and establish the car on supports.
  6. Mark chalk a belt on well foreground.
  7. 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.
  8. 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. 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 equal 13 mm.
  9. In the presence of one or several of the specified damages it is necessary to replace a belt (see. Head Engine).
  10. Make sure of correctness of landing of a belt on pulleys.

Establishing a driving belt, correctly place it on pulleys - it should be strictly on the pulley center (even short-term work of incorrectly established belt can lead to its damage)
