Drive Belt: Service and Repair

ACCESSORY DRIVE BELTS
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 are required:
1. Excessive wear.
2. Frayed cords.
3. Severe glazing.






V-Ribbed belt system with back drive 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.
