Adjusting procedure
Belt tension adjustment is made by pivoting the generator at
the alternator mounting bolt.
1) Loosen the generator adjusting plate bolt and the alternator
mounting bolt.
2) Pivot the alternator at the mounting bolt by adjusting the
adjusting bolt.
3) Tighten the mounting bolt and the adjusting bolt.
NOTICE: Belt tension may vary slightly after the alternator is fixed.
Therefore, recheck the belt tension after tightening the bolts.
4) After the adjustment, operate the engine about five minutes at a
low idle speed and recheck the belt tension. Particularly, pay
attention to this matter when installing new belts. Belt tension
may vary due to the initial belt conforming.
(2) Fan Belt Change
Use of fan belt with poor quality will result in premature belt
wear or belt elongation leading to engine damage such as
overheat. Therefore use of the ISUZU genuine fan belts are
highly recommended.
