REPLACEMENT

Powerlite Style

Remove the belt cover and drive belt. Wedge a block

of wood in the rotor and remove the locknut holding the

rotor pulley in place. Remove the rotor pulley and hub.

The bearing will now slide off the shaft. Note there is a

sleeve inside the bearing; slip it out of the bearing

(Figure 98).

Next remove the 3 capscrews that hold the bearing

flange (Figure 98). There are 3 more capscrews on the

opposite side of the snowthrower holding the bearing

flange on that side (Figure 99). Remove them at this

time.

Loosen the 4 screws on the right side of the machine

several turns (Figure 100). Push the rotor towards the

drive side and spread the rotor housing (Figure 101).

Pull the right side (opposite the drive) of the rotor

forward until it clears the housing. The drive side of the

rotor can now be pulled out of the housing (Figure

102). The bearing on the right side (opposite the

drive) of the rotor is retained by a nut (Figure 103). It

will be necessary to hold the rotor shaft in a vise or with

a pipe wrench or vise grip in order to remove the nut.
