Drive belt

DRIVE BELT : Checking

• Inspection should be done only when engine is cold or over 30 minutes after the engine is stopped.

1 : Alternator
2 : Water pump
3 : Crankshaft pulley
4 : A/C compressor
5 : Idler pulley
6 : Drive belt

• Visually check belts for wear, damage, and cracks on inside and edges.

• Turn crankshaft pulley two time clockwise, and check tension on all pulleys is equal before doing the test.

• When measuring deflection, apply 98 N (10 kg, 22 lb) at the ( ) marked point.

• Measure the belt tension and frequency with acoustic tension gauge (commercial service tool) at the ( )
marked point.

CAUTION:
• When the tension and frequency are measured, the acoustic tension gauge should be used.

• When checking immediately after installation, first adjust it to the specified value. Then, after turning crankshaft two turns or more, readjust to the specified value to avoid variation in deflection between pulleys.

Belt Deflection/Belt Tension and Frequency: Refer to EM-250, "Drive Belt".

DRIVE BELT : Tension Adjustment

CAUTION:
• When belt is replaced with new one, adjust belt tension to the value for “New belt”, because new belt will not fully seat in the pulley groove.

• When tension of the belt being used exceeds “Limit”, adjust it to the value for “After adjusted”.

• When installing a belt, check it is correctly engaged with the pulley groove.

• Never allow oil or engine coolant to get on the belt.

• Never twist or bend the belt strongly.

1. Remove front fender protector (RH). Refer to EXT-22, "Exploded View".

2. After loosening lock nut (A) of idler pulley (5) to release from the specified torque state, temporarily tighten the lock nut to the following torque

4.4 N·m (0.45 kg-m, 39 in-lb)

1 : Alternator
2 : Water pump
3 : Crankshaft pulley
4 : A/C compressor
5 : Idler pulley
6 : Drive belt

CAUTION
• When the lock nut is loosened excessively, the idler pulley tilts and the correct tension adjustment cannot be performed. Never loosen it excessively (more than 45 degrees).

• Put a matching mark on the lock nut (A), and check turning angle with a protractor. Never visually check the tightening angle.

3. Adjust the belt tension by turning the adjusting bolt (B). Refer to MA-24, "DRIVE BELT : Checking".

CAUTION:
• When checking immediately after installation, first adjust it to the specified value. Then, after turning crankshaft two turns or more, readjust to the specified value to avoid variation in deflection between pulleys.

• When the tension adjustment is performed, the lock nut should be in the condition at step“ 2”. If the tension adjustment is performed when the lock nut is loosened more than the standard, the idler pulley tilts and the correct tension adjustment cannot be performed.

4. Tighten the lock nut.
