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.
3. Using the 1/2" breaker bar, place the square end in the
opening in the idler arm (B) and rotate the idler arm
clockwise, which will relieve the tension on the belt
exerted from the idler arm.
4. Slide the drive belt over the edge of the right hand side
spindle pulley (C). Carefully release the tension on the
breaker bar.
5. Remove the old belt and replace with a new one.
6. Install the belt onto the PTO clutch pulley (D), the center
and left hand side spindle pulleys (E), the stationary idler
pulley (F) and the adjustable idler pulley (G).
7. Carefully rotate the breaker bar clockwise and install the
belt on the right hand side spindle pulley. Make sure that
the V-side of the belt runs in the grooves of the spindle
pulleys and PTO clutch pulley, and that the back side of
the belt contacts the faces of the stationary idler pulley
and the adjustable idler pulley.
8. Carefully release the tension on the breaker bar.
