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 trim 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) and the center
and discharge side spindle pulleys (C). Install the belt on
the stationary idler pulley (E) and the adjustable idler pulley
(F).
7. Carefully rotate the breaker bar clockwise and install the
belt on the trim side spindle pulley, making sure that the
V-side of the belt runs in the grooves of the pulley.
8. Carefully release the tension on the breaker bar.
