Generator Belt Inspection And Adjustment

NOTE: When using a new belt, first adjust the deflection or tension to the values for the new belt, then readjust the deflection or tension to the value for the used belt after running engine for five minutes.

DEFLECTION METHOD:

Apply a force of 98N (10kg, 22lb), and measure the deflection between the generator and the water pump pulley.

Deflection

Used belt: 4.2~4.7 mm (0.1654~0.1850 in)

New belt: 3.3~3.7 mm (0.1299~0.1457 in)

NOTE: 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

Used belt: 392.3~490.3N (40~50kg, 88.2~110.21b)

New belt: 637.4~735.5N (65~75kg, 143.3~165.31b)

NOTE: If the belt is worn or damaged, replace it.

IF ADJUSTMENT IS NECESSARY:

Loosen adjusting bolt (A) and the lock bolt (B).
Move the generator to obtain the proper belt tension, then retighten the nuts.

Recheck the deflection or tension of the belt.
NOTE: For the power steering pump belt and A/C compressor belt adjustments, refer to MECHANICAL POWER STEERING SYSTEM and AIR CONDITIONING SYSTEM .
