A/C Compressor

DEFLECTION METHOD:

Checking Belt Tension - Deflection Method:

1. Apply a force of 100 N (10 kg, 22 lbs) and measure the deflection between the alternator and crankshaft pulley.

Deflection: 10 - 12 mm (0.39 - 0.47 in)

NOTE:
- On a brand-new belt, the deflection should be 4.5 - 7 mm (0.18 - 0.28 in) when first measured.
- If there are cracks or any damage evident on the belt, replace it with a new one.

2. Loosen the through bolt and adjustment locknut.
3. Turn the adjusting bolt to obtain the proper belt tension, then retighten the nut and mounting bolt.
4. Recheck the belt deflection.

TENSION GAUGE METHOD:

Checking Belt Tension - Tension Gauge Method:

1. Attach the belt tension gauge to the belt and measure the tension of the belt.

Tension: 450 - 600 N (45 - 60 kg, 99 - 132 lbs)

NOTE:
- New belt, the tension should be 950 - 115O N (95 - 115 kg, 209 - 253 lbs) when first measured.
- Follow the manufacturer's instructions for the belt tension gauge.

- Move the gauge main body from between the P/S belts (under the P/S pump) to the alternator belt, and attach it there at the measuring point. Then connect the gauge handle to its main body.
- If there are cracks or any damage evident on the belt, replace it with a new one.

2. Loosen the through bolt and adjustment locknut.
3. Turn the adjusting bolt to obtain the proper belt tension, then retighten the nut and mounting bolt.
4. Recheck the tension of the belt.
