PERIODIC INSPECTION AND MAINTENANCE PROCEDURES

Inspection of V-belt and Adjustment of Belt Tension
If damage or surface separation is found on the V-belt during inspection, replace the 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 the belt tension accurately by following the procedures below.
Inspecting the V-belt
1 Inspect the external appearance of the V-belt. If damage or surface separation is found on the V-belt,
replace the V-belt with a new belt.
2 When force (approx. 98 to 147 N [10 to 15 kgf]) applied to the center section of the V-belt causes the belt
to deflect 10 to 15 mm [0.39 to 0.59 in.], the belt tension is appropriate.
3 To adjust the belt tension, turn the adjusting rod.
Adjusting the V-belt tension (Alternator
side)
1 Remove the alternator front cover and belt
cover.
2 Loosen all retaining bolts on the alternator and
adjusting rod.
3 Loosen the upper and lower lock nuts on the
adjusting rod.
Note: Note that the lower nut on the adjusting rod
has left-hand threads.
4 Turn the adjusting rod to adjust the V-belt ten-
sion.
5 After the tension adjustment, tighten the upper
and lower lock nuts.
6 Tighten all the retaining bolts on the alternator and adjusting rod.
7 Reinstall the alternator front cover and belt cover.
Adjusting the V-belt tension (Water pump side)
1 Remove the belt cover.
2 Loosen all the retaining bolts on the tension pulley sliding plate.
3 Loosen the lock nuts on the adjusting rod and tighten the bolts to have belt tension.
4 Retighten all the retaining bolts on the tension pulley sliding plate.
5 Reinstall the belt cover.
