Checking Drive Belts

Scheme 22

1. Inspect belts for cracks, fraying, wear and oil. If necessary, replace.
2. Inspect drive belt deflection or tension at a point on 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 down triangle shown in the figure. When measuring the deflection, apply 98 N (10 kg, 22 lb) at down triangle the marked point. Adjust if the belt deflection exceeds the limit or if the belt tension is not within specifications. CAUTION: When checking the belt deflection or the tension immediately after installation, first adjust it to the specified value. Then, after turning 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 the tension without looseness. Belt Deflection and Tension
