Accessory Drive Belts

Print

Adjustment



The accessory drive belt is automatically tensioned by a spring-loaded tensioner.

Belt Tension Inspection



Inspect the drive belt for signs of glazing or cracking. A glazed belt will be perfectly smooth from slippage, while a good belt will have a slight texture of fabric visible. Cracks will usually start at the inner edge of the belt and run outward. All worn or damaged drive belts should be replaced immediately.
