Belt Maintenance

Servicing the Alternator
Belt
Service Interval: After the first 10 hours
Every 100 hours
Proper tension allows 10 mm (3/8 inch) of deflection
when a force of 44 N∙m (10 ft-lb) is applied on the belt
midway between the pulleys.
If the deflection is not 10 mm (3/8 inch), loosen the
alternator-mounting bolts
Note:
Increase or decrease the alternator-belt
tension and tighten the bolts. Check the deflection of
the belt again to ensure that the tension is correct.

Service Interval: After the first 10 hours
Every 50 hours
When properly tensioned, the inside measurement
of the extension spring (hook to hook) should be
approximately 8.3 to 9.5 cm (3-1/4 to 3-3/4 inches).
Once the correct spring tension is attained, adjust the
stop bolt (carriage bolt) until there is approximately 2
to 5 mm (0.065 to 0.185 inch) clearance between the
head of the bolt and the idler arm
Note:
Ensure that the belt is positioned on the spring
side of the belt guide
