wait for all moving parts to stop.

A WARNING
Use extreme cautionwhen rotatingthe idler arm with
the breakerbar, due to increased tensionin the spring
as the idler arm is being rotated. Injury may result if
the breakerbar is prematurelyreleasedwhile the
spring is under tension.
4. Using a 1/2" breaker bar, placethe square end in the
square hole located in the idler arm (A, Figure44).
Carefully rotate the breaker bar COUNTER-CLOCKWISE,
which will relieve the tension on the belt exerted from the
idler arm. Slide the belt off the stationary idler pulley
(B).
5. Carefully releasethe tension on the breaker bar.
6. Removethe old drive belt and install the new one as
shown in Figure45. Make sure that the V-side of the belt
runs in the pulley groves of the spindle pulleys, and that
the back of the drive belt must ride against the back-side
idler pulleys (B).
7. Install the belt on the PTOpulley, the spindle pulleys and
all the idler pulleys except the stationary idler pulley (B,
Figure44). Carefully rotate the breaker bar COUNTER-
CLOCKWISE and install the belt on the stationary idler
pulley. Carefully releasethe tension on the breaker bar.
