Condition and Tension
Check condition and tension of belt (Fig. 38) after every
100 operating hours.
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.
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.
