Drive Belts, Mounts, Brackets and Accessories: Testing and Inspection

Checking Drive Belts





1. Inspect belts 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 (BT 3373-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.

Belt deflection and tension:





*1: If the belt tension gauge cannot be installed at check points shown, check drive belt tension at a different location on the belt.
