Drive Belt Inspection and Adjustment

Special Tools Required
Belt tension gauge (  07JGG-0010101)
 



NOTE: This inspection must be done at engine cold condition.

Used Belt


1.Remove the engine undercover

2.Inspect the belt for cracks and damage. If the belt is cracked or damaged, replace it.

Inspection with Belt Tension Gauge Method


3.Turn the crankshaft pulley one turn or more. Attach the belt tension gauge to the belt and measure the tension. Follow the gauge manufacturer's instructions. If the belt needs adjustment, go to 5.

Tension: 440-590 N (45-60 kgf, 99-130 lbf) 


With A/C 

Without A/C 

Inspection with Deflection Method


4.Turn the crankshaft pulley one turn or more. Apply a force of 98 N (10 kgf, 22 lbf), and measure the deflection at the mid point (A) between A/C compressor (alternator for without A/C) and crankshaft pulley. If the belt needs adjustment, go to 5.

Deflection 
With A/C: 5.5-8.5 mm (0.22-0.33 in.) 
Without A/C: 7.5-10.5 mm (0.30-0.41 in.) 


With A/C 

Without A/C 

Adjustment


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

 

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

7.Recheck the belt tension.

New Belt


1.Remove the engine undercover (With A/C).

Inspection with Belt Tension Gauge Method


2.Attach the belt tension gauge to the belt and measure the tension. Follow the gauge manufacturer's instructions. If the belt needs adjustment, go to 4.

NOTE: Does not turn the crankshaft pulley before measuring the belt tension.

Tension: 981-1,080 N (100-110 kgf, 220-243 lbf) 


With A/C 

Without A/C 

Inspection with Deflection Method


3.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) and crankshaft pulley. If the belt If the belt needs adjustment, go to 4.

NOTE: Does not turn the crankshaft pulley before measuring the belt deflection.

Deflection
With A/C: 3.5-5.0 mm (0.14-0.20 in.) 
Without A/C: 4.5-6.0 mm (0.18-0.24 in.) 


With A/C 

Without A/C 

Adjustment


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

 

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

6.Recheck the belt tension.
