Belt Tension

Inspect belts for excessive cracking or fraying. Measure tension on longest span of belt with a belt tension gauge. Generator belt tension for a new belt is 150-170 lbs. (68-77 kg), or 125-145 lbs. (57-66 kg) for a used belt. Belt may also be checked by deflection of longest span of belt. Generator belt deflection for a new belt is 1/4-5/16" (6.5-7.5 mm), or 5/16-11/32" (7.5-8.5 mm) for a used belt.
