Drive Belt: Testing and Inspection

Drive Belts

CHECKING DRIVE BELTS

WARNING: Be sure to perform when the engine is not running.

1. Inspect belt for cracks fraying wear or oil adhesion. If necessary replace with a new one.





2. Inspect drive belt deflections by applying 98N (10 kg, 22 lbs.) on the belt midway between pulleys as shown.
3. Measure the belt tension using Tool at the locations shown.
Tool number : BT-3373-F

NOTE:
^ Inspect drive belt deflection or tension when engine is cold.
^ Adjust if belt deflections exceed the limit or if belt tension is not within specifications.





CAUTION:
^ When checking belt deflection or tension immediately after installation. first adjust it to the specification value. Then, after turning the crankshaft two turns or more, readjust to the specified value to avoid variation in deflection between pulleys.
^ Tighten idler pulley lock nut by hand and measure deflection or tension without looseness.
