Drive Belt: Testing and Inspection

Engine Drive Belts

V-belts should be inspected during regular maintenance intervals.
Incorrect tension can decrease the life ot the belt and the component it drives. The V-belt tension is adjusted through a toothed-rack mechanism.
If the belt shows signs of wear, cracking, glazing, or missing sections, it should be replaced immediately.
Inspect belts with the engine off. Twist the belt to inspect its sidewalls and bottom. Belt structural damage, glazed or shiny sidewalls caused by a loose belt, or separation are all reasons to replace a belt.
