3.20. Check of a condition of a belt of the drive of auxiliary units
The tension of a driving belt (maple or multiridge) is regulated automatically, however it should be checked periodically together with a condition of a belt.
Fingers walk on all length of a belt, feeling it on existence of cracks and stratifications. Also check whether is not present on a belt of attritions and sites, zapolirovanny to gloss. The belt should be examined on both sides that means need of its twisting. 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.
Wear of edges of edges of a driving belt
Cross cracks (D) from a reverse side of a belt and peeling of edges (E)
Razlokhmachivaniye of side edges (F), cracks (H) and peeling of side edges (G)
Separation of edges (J), cracks (K)
Make sure of correctness of provision of a belt on pulleys.
