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.

opening located in the idler arm (A, Figure 81). Carefully
rotate the breaker bar counter-clockwise, which will
relieve the tension on the belt (B) exerted from the idler
arm.
