to change the belt tension, the belt alignment must be maintained.

14. Place a belt gauge (McMaster-Carr 6160K12 or Grainger 3HX33) in the middle of the step

up belt and the center of the belt span (see Diagram 5.5). Lay a straight edge along the

length of the belt and beside the belt gauge. Slide one of the o-rings up against the shoulder

of the belt gauge. Press downward on the belt gauge, causing the belt to deflect. Read the

deflection on the belt gauge at the edge of the straight edge. Deflect the belt 1/4”. Read the

tension across the top edge of the o-ring. If the belt is correctly tensioned the gauge will

read between 19 and 21 pounds.

15. If the tension in step 13 is correct skip to step 18. Otherwise continue with the next step.
