10) Position the bottom of the belt gauge’s large o-ring on the Span Scale at the measured belt span
(14”).
11) Set the small o-ring on the Deflection Force Scale to zero.
12) Place the tension tester squarely on the back belt at the center of the belt span. Apply a force on
the plunger and perpendicular to the belt span until the bottom of the large o-ring is even with the
top of the next belt (14” on the scale).
13) Remove the tension tester and read the force applied from the bottom of the small o-ring on the
deflection force scale.
14) At this point the back belt tension should read 11 lbs. for a new belt or 7 lbs. for a used belt.
15) Tighten bolt (B2) and rotate the large pump pulley CCW 2 turns.
16) Tighten adjustment screw (D) until the front belt is at 13 lbs. for a new belt or 9 lbs. for a used belt.
17) Tighten fasteners B1, A1 and B2.
18) Check the tension of all 3 belts. They should be 13 ± 2 lbs. for a new belt or 9 ± 1 lb. for a used
belt.
Note: See the belt-tightening chart on the previous page.

19) Belt tension will affect the pulley alignment. Check the pulley alignment with a straight edge on the
large pulley, extending up to the small pulley. If they are not within 1/8” then loosen the belts, slide
the small pulley in or out as necessary, and repeat steps 5 thru 13.
20) Tighten Jam Nut (C).
21) Replace the Belt Guard.
22) Turn the system Main Disconnect back on.
