To replace the belt follow these instructions and refer to Figure 18:
Belt Keeper
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.
CAUTION
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 pave-
ment. Doing so can result in serious damage to your snow thrower.
To change the rubber paddles, proceed as follows and refer to Figure
19:
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 19.
NOTE: The auger paddles should be replaced one at a time so that
the auger paddle still attached can be used as an example for position-
ing and re-installing the new auger.
4. Secure the replacement rubber paddles to the auger using the
hardware removed earlier.
To obtain a full auger replacement kit including rubber paddles and
hex washer screws, call Sears at 1-800-4-MY HOME. Ask for part

REVERSING OR REPLACING SHAVE PLATE
The shave plate is attached to the bottom of the auger housing and
is subject to wear. It should be checked periodically. There are two
wearing edges and the shave plate can be reversed.
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 four carriage bolts and flange lock nuts which attach
it to the snow thrower housing. Refer to Figure 14 on page 14.
4. Install the new shave plate, making sure the heads of the carriage
bolts are on the inside of the housing.
5. Tip the snow thrower back to the operating position and pull the
starter handle a few times to see if it is difficult to pull.
6. If the starter is difficult to pull, remove the spark plug and pull the
handle several times to ensure that any oil trapped in the head is
removed.
Oil may come out of the spark plug hole when it is removed and the
starter handle is pulled.
7. Inspect the spark plug. If it is wet, clean off any oil before
re-installing.
8. Adjust the shave plate as instructed in the Maintenance & Adjust-
ments section.
9. Tighten securely once adjusted.
To obtain a new shave plate, call Sears at 1-800-4-MY-HOME. Ask for
