Drive Belt: Testing and Inspection

INSPECTION 

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 belt has chunks missing from the ribs, it should be replaced.

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

Belt tension gauge:
DENSO BTG-20 (95506-00020)
Boroughs No. BT-33-73F
Drive belt tension:
New belt: 135 - 180 lbs. 
Used belt: 85 - 120 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.
