Alternator Belt

1. Condition and Tension – Check condition and tension
of belts (Fig. 41) after every 100 operating hours.
A. Proper tension will allow 3/8 in. (10 mm) deflection
when a force of 10 lbs. is applied on the belt
midway between the pulleys.
B. If deflection is not 3/8 in. (10 mm), loosen alternator
mounting bolts. Increase or decrease alternator belt
tension and tighten bolts. Check deflection of belt
again to assure tension is correct.
