Alternator: Adjustments

Alternator Brush Inspection And Adjustment:

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

NOTE:
^ On a brand-new belt (one that has been run for less than five minutes), the deflection should be
*1 5.0 - 7.0 mm (0.20 - 0.28 in) or
*2 6.0 - 8.5 mm (0.26 - 0.33 in)
when first measured.
*1: B16A2 engine
*2: D16Y7, D16Y8 engines
^ If the belt is worn or damaged, replace it.

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.

Alternator Brush Inspection And Adjustment:

Tension gauge method:
Following the gauge manufacturer's instructions, attach the special tool to the belt, and measure the tension.

NOTE:
^ On a brand-new belt (one that has been run for less than five minutes), the tension should be
*1 690 - 880 N (70 - 90 Kgf, 144 - 199 lbf) or
*2 540 - 740 N (55 - 75 Kgf, 121 - 165 lbf)
when first measured.
*1: B16A2 engine
*2: D16Y7, D16Y8 engines
^ If the belt is worn or damaged, replace it.

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 tension of the belt.
