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. If the belt is not properly seated, use a 1/2" breaker bar
(B), and place the square end in the opening in the idler
arm (C).
5. Carefully rotate the breaker bar clockwise, pulling the
adjustable idler pulley away from the idler arm stop (L).
This will will relieve the tension on the belt exerted from
the idler arm.
6. Re-seat the belt and carefully release the tension on the
breaker bar.
