Alternator Belt

Use a tension gauge to measure the belt tension or apply a force of 98 N (22 lbs.) to the mid-point of the belt between the generator pulley and crankshaft pulley and measure deflection. Deflection should be 0.35-0.47 inch (9.0-12.0mm). If using a tension gauge, tension should be 90-110 lbs. (400-490 N).

Belt Tension Inspection



Check the accessory drive belts for evidence of damage, cuts, cracks or any unusual wear and replace if necessary.

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.
