Drive Belt: Testing and Inspection




1. Inspect belt for cracks, fraying, wear and oil. If necessary, replace.
2. Inspect drive belt deflection or tension at a point on the belt midway between pulleys. Check belt tension using belt tension gauge (BT3373-F or equivalent).
- Inspect drive belt deflection or tension when engine is cold. Adjust if belt deflection exceeds the limit or if belt tension is not within specifications.
- Belt tension can also be checked at other points on the belt.
