Belts

INSPECTION



See Figures 1, 2, 3, 4 and 5

Inspect the belts 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. It is best to replace all drive belts at one time, as a preventive maintenance measure, during this service operation.

ADJUSTING



Belt deflection at the midpoint of the longest span between pulleys should not be more than 1 / 2 in. (13mm) with 22 lbs. (10kg) of pressure applied to the belt.

REMOVAL & INSTALLATION



See Figures 15 and 16

The replacement of the inner belt on multi-belted engines may require the removal of the outer belts.

To replace a drive belt, loosen the adjusting and mounting bolts of the component which the belt is driving. Move the component inward to relieve the tension on the drive belt.

Fig. Fig. 15: After the tension on the belt is relieved, slip the belt from the pulley

Fig. Fig. 16: The replacement of some belts may require the removal of other belts

Slip the belt off the component pulley and match the new belt with the old belt for length and width. The old belt will be slightly longer. After a new belt is installed correctly, adjust the tension.

When replacing more than 1 belt, it is a good idea to make note or mark what belt goes around what pulley; this will make installation easier if you mix up the belts.
