6. Position the pulley bolt through the bracket and spacer.
7. Now install the idler pulley on the bolt with its hub facing against the back side U-bracket.
8. Secure the nyloc nut and tighten.
9. Place the main drive belt onto the idler pulley.
10. Position the wear plate between the slots of the U-bracket up against the frame.
11. Turn in the tensioning bolt as required to adjust the belt tension.
12. Using a belt tensioning gauge, adjust new belt tension from 165 to 170 lbs, and existing belt
from 160 to 165 lbs. If a belt tensioning gauge is unavailable, place a straight edge between the
intermediate pulley and the crank pulley then at the center of the belt press down on the belt
and measure for deflection which should be a 1/4 inch.
13. With the main drive belt properly tensioned, tighten the bracket mounting bolts 5 to 10 ft. lbs.
NOTE: Over tightening the mounting bolts will cause damage to the slide plate.
