Inspecting V-belt and adjusting belt tension
&$87,21
If defects such as cuts or surface separations are found on V-belt during inspection, replace V-belt. Keep oil and
grease away from the belt, since they may cause the belt to slip and shorten the service life.
Excessive V-belt tension can cause rapid wear of the alternator bearing and shorten the service life of the belt.
Adjust belt tension accurately by following the procedures below.
Inspecting V-belt
1. Inspect V-belt for defects such as wear, cuts or surface separations. If defects are found, replace V-belt with a
new belt.
2. Inspect belt tension (deflection amount) as instructed below:
Push the belt downward at the midway between pulleys. If the deflection is 10 mm [0.39 in.] , the tension is cor-
rect.
V-belt pushing force：Approx. 98 N {10 kgf} [22 lbf]
If the tension is out of the specified value, adjust belt tension.
Adjusting V-belt tension
1. Remove belt cover that covers V-belt.
2. Loosen all retaining bolts of the alternator and
adjusting plate.
3. Insert a bar between the alternator and cylinder
block and use leverage to move the alternator to
have proper V-belt tension.
4. While V-belt tension is appropriate, retighten all the
retaining bolts of the alternator and adjusting plate.
5. Reinstall the belt cover.

Checking and cleaning the radi-
ator fins
When using compressed air, wear protective gear
such as safety glasses, a hard hat and gloves. Work-
ing without protective gear can result in a severe per-
sonal injury.
Check the radiator fins for holes and cracks.
To clean the radiator fins, blow compressed air from
the opposite direction of the normal air flow.
