Drive Belt: Adjustments

DRIVE BELTS TENSION




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:

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






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