Drive Belt Inspection and Adjustment

Drive Belt Inspection and Adjustment

Special Tools Required
Belt tension gauge (  07JGG-0010100)
 



Belt Tension Gauge Method

Inspection

1.Attach the belt tension gauge to the belt and measure the tension. Follow the gauge manufacturer's instructions. If the belt is worn or damaged, replace it. If the belt needs adjustment, go to step 2.

Tension:
Used Belt: 440-590 N (45-60 kgf, 99-130 lbf) 
New Belt: 981-1,130 N (100-115 kgf, 220-254 lbf) 


With A/C compressor: 

Without A/C compressor: 

Adjustment

2.Loosen the lock bolt (A) and mounting bolt (B).

 

3.Turn the adjusting bolt (C) to obtain the proper belt tension, then retighten the lock bolt and mounting bolt.

4.Recheck the belt tension.

5.If you installed a new belt, run the engine for 5 minutes, then readjust the belt to the used belt specification.

Deflection Method


Inspection

1.Apply a force of 98 N (10 kgf, 22 lbf), and measure the deflection at the mid point (A) between the A/C compressor (alternator for without A/C compressor) and crankshaft pulley. If the belt is worn or damaged, replace it. If the belt needs adjustment, go to step 2.

Deflection:
With A/C compressor: 
Used Belt: 5.5-8.5 mm (0.22-0.33 in.) 
New Belt: 3.5-5.0 mm (0.14-0.20 in.) 
Without A/C compressor: 
Used Belt: 7.5-10.5 mm (0.30-0.41 in.) 
New Belt: 4.5-6.0 mm (0.18-0.24 in.) 


With A/C compressor: 

Without A/C compressor: 

Adjustment

2.Loosen the lock bolt (A) and mounting bolt (B).

 

3.Turn the adjusting bolt (C) to obtain the proper belt tension, then retighten the lock bolt and mounting bolt.

4.Recheck the belt tension.

5.If you installed a new belt, run the engine for 5 minutes, then readjust the belt to the used belt specification.
