WARNING
Use extreme caution when rotating the idler arm with the
breaker bar, due to the increased tension in the spring
as the idler arm is being rotated. Injury may result if the
breaker bar is prematurely released while the spring is
under tension.
4. Using the 1/2” breaker bar, place the square end in the
opening in the idler arm (B) and rotate the idler arm
counter-clockwise
, which will relieve the tension on the
belt exerted from the idler arm.
5. Slide the drive belt over the edge of the right hand side
spindle pulley (C). Carefully release the tension on the
breaker bar.
6. Remove the old belt and replace with a new one.
7. Install the belt onto the left hand side double spindle
pulley (D) and the adjustable idler pulley (E).
8. Carefully rotate the breaker bar
counter-clockwise
and install the belt on the right hand side spindle pulley,
making sure that the V-side of hte belt runs in the grooves
of all of the pulleys.
