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.
