Auger Pulley
1. Route the belt around the drive pulley and under the idler pulley.
2. Route the end of the belt around the auger pulley and slide the pulley back
on to the auger shaft. It may be necessary to push down on the idler pulley
to get the auger pulley under the belt keeper.
3. Replace the flange nut and tighten securely.
4. Reinstall the belt cover removed earlier.
5. Remove the board from the auger and chute.
Replacing Auger Paddles
The snow thrower auger's rubber paddles are subject to wear and should be
replaced if any signs of excessive wear are present.
Do NOT allow the auger's rubber paddles to wear to the point where
portions of the metal auger itself can come in contact with the pavement.
Doing so can result in serious damage to your snow thrower.

CAUTION
To change the rubber paddles, proceed as follows and refer to Figure 22:
Auger Paddle
1. Run the snow thrower until the fuel tank is empty.
2. Pull the recoil starter handle until resistance is felt. Then tip the snow
thrower back until it rests on the handles.
3. Remove the existing rubber paddles by unthreading the hex washer screws
which secure them to the auger. See Figure 22.
NOTE: The auger paddles should be replaced one-at-a-time so that the auger
still attached can be used as an example for positioning and re-installing the
new auger.
4. Secure the replacement rubber paddles to the auger using the hardware
removed earlier.

screws, may be obtained through Sears Parts & Repair or by calling 1-800-659-5917.

2. Pull the recoil starter handle until resistance is felt. Then tip the snow
thrower back until it rests on the handles.
3. Remove the four carriage bolts and flange lock nuts which attach it to the
snow thrower housing.
4. Reverse the existing shave plate or install a new one, making sure the new
shave plate and the heads of the carriage bolts are on the inside of the
housing.
5. Adjust the shave plate as instructed on page 15.
