Checking Drive Belts



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.
- Drive belt tension can also be checked at other points on the belts.
