INSPECTION - ACCESSORY DRIVE BELT
Satisfactory performance of the belt driven accessories depends on belt condition and proper belt tension.
Belt replacement under any or all of the following conditions is required:
^ Excessive wear.
^ Frayed cords.
^ Severe glazing.





The Poly-V belt with a back driven pulley may develop minor cracks across the ribbed side (due to reverse bending). These minor cracks are considered normal and acceptable. Parallel cracks are not (Fig. 2).
