Servicing the Engine Belts
Check tension of all belts initially after the first day of
operation and every 100 hours thereafter.
Alternator Belt
1. Unlatch and open hood.
2. Proper tension will allow 3/8 in. (10 mm) deflection
when a force of 10 lbs. is applied on the belt (Fig. 52)
midway between the pulleys.
3. 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.

3. Belt should deflect 1/4 in. (6 mm) midway between the
pulleys with 5 lb. force (22 n) (Fig. 54). If deflection is
incorrect, proceed to step 4. If correct, proceed to
step 5.

4. Loosen locknut securing adjustable idler pulley
(Fig. 54). Push idler pulley against belt until proper
deflection is achieved and tighten idler pulley locknut
(Fig. 54).
