Alternator

Alternator Belt Deflection Check:

Deflection Method
Apply a force of 100 Nm (10 kg, 22 lbs) and measure the belt deflection between the alternator and the crankshaft pulley.

Deflection: 7.0 - 10.5 mm (0.28 - 0.41 in)

NOTE:
^ On a brand-new belt (one that has been run for less than five minutes), the deflection should be 5.5 - 8.0 mm (0.22 - 0.31 in) when first measured.
^ If there are cracks or any damage evident in the belt, replace it with a new one.

Alternator Belt Tension Check:

Tension Gauge Method
Attach the belt tension gauge to the belt and measure the belt tension.
Tension: 350-500 N (35-50kg, 77 - 110 lbs)

NOTE:
^ On a brand-new belt (one that has been run for less than five minutes), the tension should be 550 - 750 N (55 - 75kg, 121 - 165 lbs) when first measured.
^ Follow the manufacturer's instructions for the belt tension gauge.
^ If there are cracks or any damage evident in the belt, replace it with a new one.




If adjustment is necessary:
1. Loosen the alternator adjusting bolt and the through bolt nut.
2. Move the alternator to obtain the proper belt tension, then retighten the adjusting bolt and the through bolt nut to the specified torques.
3. Recheck the deflection of the belt.
