Oiwa Garage Tech Note

"There is a large inspection grommet in the belt cover. Pop it out and you can check the belt condition and tightness without pulling the cover off. Set the belt to 9-12 mm of travel. Too loose and it squeals and undercharges. Too tight and it kills the alternator bearing."

Frequently Asked Questions

How tight should the belt be?

Set it to 20-30 kgf on a belt tension gauge, which works out to 9-12 mm of travel at the mid-span. Torque the adjustment bolt to 2.5 kgm and the pivot bolt to 4.5 kgm. Recheck after a short drive as a new belt beds in.

How do I check the alternator belt?

There is a large inspection grommet in the belt cover, so you can check condition and tightness without taking the cover off. Look for cracks, glazing, or fraying, then press the mid-span. More than 12 mm of travel means it is loose. A squeal on start-up or under load is the audible sign.

How often should the alternator belt be replaced?

The manual calls for a new belt at 68,000 km (42,000 miles). On a truck this old, go by age and condition as well. Rubber hardens and cracks whether the belt is turning or sitting.
