DRIVE BELT

INSPECTION

INSPECT DRIVE BELT
Visually check the belt for excessive wear, frayed cords, etc.
If any defect has been found, replace the drive belt.
HINT:
Cracks on the rib side of the belt are considered acceptable. If
the missing chunks from the ribs are found on the belt, it should
be replaced.

HINT:

”New belt” refers to a belt which has been used less than
5 minutes on a running engine.

”Used belt” refers to a belt which has been used on a run-
ning engine for 5 minutes or more.

After installing a belt, check that it fits properly in the
ribbed grooves.

Check with your hand to confirm that the belt has not
slipped out of the groove on the bottom of the pulley.

After installing a new belt, run the engine for about 5 min-
utes and recheck the belt tension.
