Alternator Belt

Alternator Belt Inspection and Adjustment

Deflection method:
Apply a force of 98 N (10 kgf, 22 lbf), and measure the deflection between the alternator and crankshaft pulley.

Deflection: 9.0 - 11.5 mm (0.35 - 0.45 in)

Alternator Belt Inspection And Adjustment:

NOTE: On a brand-new belt (one that has been run for less than five minutes), the deflection should be 5.5 - 7.0 mm (0.22 - 0.28 in) when first measured. If the belt is worn or damaged, replace it.

Belt tension gauge method:
Attach the belt tension gauge to the belt and measure the tension. Follow the gauge manufacturer's instructions.

Tension: 390 - 590 N (40 - 60 kgf, 88 - 132 lbf)

Alternator Belt Inspection And Adjustment:

NOTE: On a brand-new belt, (one that has been run for less than five minutes), the tension should be 785 - 980 N (80 - 100 kgf, 176 - 220 lbf) when first measured. If the belt is worn or damaged, replace it.

If adjustment is necessary:
1. Loosen the lower mounting bolt and the adjusting lock bolt.

Alternator Belt Inspection And Adjustment:

2. Move the alternator by turning the adjusting rod to obtain the proper belt tension, then retighten the bolts.
3. Recheck the deflection or tension of the belt.
