Drive Belt: Testing and Inspection

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

HINT:
- If any defect 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 with your hand to confirm that the belt has not slipped out of the groove on the bottom of the pulley.








INSPECT V-RIBBED BELT





a. Belt deflection
Pressing force: 98 N (10 kgf, 221 lbs.)





b. Tension

NOTICE:
^ Check the drive belt deflection at the specified point.
^ When installing a new belt, set its tension value as specified.
^ When checking a belt used for over 5 minutes, confirm the deflection value is within the specified one.
^ When reinstalling a belt used for over 5 minutes, perform the check based on the used deflection value.
^ V-ribbed belt tension and deflection value should be checked after 2 revolutions of engine cranking.
^ When using a belt tension gauge, confirm the accuracy first by using a master gauge.
