Drive Belt: Testing and Inspection

INSPECT DRIVE BELT
a. Visually check the belt for excessive wear, frayed cords etc.

HINT:
- If any defect is found, replace the drive belt.
- Cracks on the rib side of a belt are considered acceptable.
If the belt has chunks missing from the ribs, it should be replaced.




b. Check that it fits properly in the ribbed grooves.

HINT: Check by hand to confirm that the belt is not slipped out of the groove on the bottom of the pulley.






INSPECT V-RIBBED BELT





a. Check the V-ribbed belt deflection.
1. Measure the belt deflection
Pressing force: 98 N (10 kgf, 22 lbs.)





2. Belt tension

NOTICE:
^ Check the drive belt deflection at the specified point.
^ When installing a new belt, set its tension value as specified.
^ When inspecting the belt which is used over 5 minutes, apply the specification of "Used Belt".
^ When reinstalling the belt which is used over 5 minutes, adjust its deflection and tension to the intermediate value of each specification of "Used Belt".
^ V-ribbed belt tension and deflection should be checked after two revolution of engine cranking.
^ When using a belt tension gauge, confirm the accuracy by using a master gauge first.
