DRIVE BELT (DAILY)
Drive Belt Tension
A slack drive belt (Figure 72) may contribute to overheating
or insufficient charging of the battery. Adjust the drive belt
in accordance with the Isuzu Operator's manual.
Drive Belt Inspection
Inspect the drive belt for damage and wear. Horizontal
cracks (across the belt) are acceptable. Vertical (direction
of belt ribs) cracks that intersect with horizontal cracks are
not acceptable.
Also, examine the belt and determine if it is oil soaked or
"glazed " (a hard shiny appearance on the sides of the belt).
Either of these two conditions can cause the belt to run hot,
which can weaken it and increase the danger of it breaking.
If the drive belt exhibits any of the above wear conditions,
replace the drive belt immediately.
