Checking Drive Belts: Notes
WARNING:
Be sure to perform when the engine is stopped.
- Inspect belts for cracks, fraying, wear and oil. If necessary, replace.
- Inspect drive belt deflection or tension at a point on the belt midway between pulleys.
- Inspection should be done only when engine is cold, or over 30 minutes after engine is stopped.
- Measure the belt tension with belt tension gauge (commercial service tool: BT3373-F or equivalent) at points marked in the figure.
- When measuring deflection, apply 98 N (10 kg, 22 lb) at the marked point.
- Adjust if belt deflection exceeds 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 specified value. Then, after turning the crankshaft two turns or more, re-adjust to the specified value to avoid variation in deflection between pulleys.
- Tighten idler pulley lock nut by hand and measure the deflection or tension without looseness.
