Accessory Drive Belts

Print

Adjustment



The belt tension is maintained by an automatic tensioner. No adjustment is necessary or possible.

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.
