Rotor Pulley Replacement
1. Refer to "Replacing Drive Belt" on page 5 - 1.
Complete steps 1 through 4.
2. Place a block of wood, (2” x 4”) as a wedge
between the rotor assembly and the housing
(Figure 70). With the use of a socket and a large
breaker bar turn the rotor pulley clockwise (Note:
The pulley is a left hand thread.) Remove the
rotor pulley.

3. Before replacing with a new rotor pulley, be certain
to place the thin washer over the shaft first (Figure
71). If not, it will be very difficult to remove in the
future and binding between the rotor and side
plates may occur.

4. Next, turn the rotor pulley onto the shaft
(counterclockwise) finger tight (Figure 72). The
rotation of the pulley during operation will tighten
the pulley to the proper torque.
5. Replace the belt. Refer to "Replacing Drive Belt"
on page 5 - 1. Complete steps 5 through 7.
