Drive Belt: Testing and Inspection

INSPECTION 

1. INSPECT DRIVE BELT.

a. 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 a belt are considered acceptable. If the missing chunks from the ribs are found on the belt, it should be
replaced.

b. Using a belt tension gauge, measure the belt tension.

Belt tension gauge: DENSO BTG-20 (95500-00020) Borroughs No. BT-33-73F
Drive belt tension:
-

New belt: 150-185 lbs. 

-

Used belt: 95-135 lbs. 

If the belt tension is not as specified, adjust it.

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 running 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 minutes and recheck the belt tension.
