Adjusting procedure
Belt tension adjustment is made by pivoting the alternator at the
alternator mounting bolt.
1) Loosen the lock nut 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 lock nut.
Tightening torque : 23.5 Nm (2.4 kgm) (M8 bolt or nut)
48.1 Nm (4.9 kgm) (M10 bolt or nut)
CAUTION:
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.
When you check the belt and find the following condition, replace the
belt with new one.
1) No adjustment margin of the belt.
2) Abnormal wear, damages, or cracks on the belt.
3) Brake noise occurs while driving even if belt tension is adjusted.
