Do not use the belt tension chart for belts with tensioners that are spring loaded.
Measure the tension of the belt that is farthest from the engine.
(1) Belt tension “lnitial” is for a new belt.
(2) Belt tension “Used” is for a belt that has operated for 30 minutes or more of operation at the rated speed.
(3) If a belt falls below the “Used” belt tension, the belt should be tightened again to the high side of the “Used” belt tension.
