ADJUSTMENT
1. For consistent measurements, use belt
tension gauge tool BT3373-F to check the
belt tension.
2. Check tension at the center of the longest
span, and chalk-mark the point checked.
3. When installing new belt(s), initially adjust
the tension to give a gauge reading of
130–150 lbs. (578–667 N). Chalk-mark the
point checked. Run the engine for
approximately 5–10 minutes. Allow the
belt(s) to cool and recheck at the chalk
mark. If the tension is less than 100 lbs.
(445 N), readjust the tension to
approximately 110–120 lbs.
(489–534 N).
4. After adjusting belt tension, tighten
alternator mounting bolts as follows:
a. Tighten upper alternator adjusting
capscrew (2) to 60–70 lb-ft
(81–95 N폷m) using torque wrench
J 24407 or equivalent.
b. Tighten lower alternator mounting
fasteners (3 and 6) to 60–70 lb-ft
(81–95 N폷m) using torque wrench
J 24407 or equivalent.
With other belt types and configurations, refer to
the current Maintenance and Lubrication Manual,
