Drive Belt: Testing and Inspection

INSPECT BELT, V-RIBBED


HINT: Use of the automatic tensioner has made the tension and flexibility measurements unnecessary.

a. Check that the indicator mark on the automatic tensioner is within the A range as shown in the illustration.
b. When the mark is out of the standard range, exchange the V belt with new one.


INSPECT DRIVE BELT




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

HINT:
- If any defect has been 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.
