Drive Belt: Adjustments

1. Check that the belts are not damaged and fit properly into the pulley grooves.

CAUTION:
1. When installing the V-ribbed belt, check that the V-ribs are properly aligned.
2. If noise or slippage is detected, check the belt for wear, damage, or breakage on the pulley contact surface, and check the pulley for scoring. Also check for the proper belt deflection measurement.

2. Apply 100 N (22 lbs.) force to the belt back midway between the pulleys as shown in the illustration, measure the amount of deflection with a tension gauge.











Standard value:
The drive belt tension is adjusted automatically by autotensioner.






Adjustment
1. Loosen the tension pulley fixing bolt A.
2. Adjust the belt deflection with adjustment bolt B.
3. Tighten the fixing bolt A.
4. Re-check the belt deflection and re-adjust, if necessary.

NOTE: Before re-checking, crank the engine one or more revolutions.






Type A tension gauge
Do not let the dial section of the tension gauge contact other objects during measurement.






Type B tension gauge
1. When measuring, turn the reset button in the direction of the arrow to set the gauge needle to the RESET position.
2. When the tension gauge is removed from the belt, the needle will still indicate the tension. Read the tension after removing the gauge.
