How To Adjust Or Replace The Friction
Wheel
How To Check The Friction Wheel
If the snow thrower will not move forward, check
thetractiondrivebelt,thetractiondrivecableor
the friction wheel. If the friction wheel is worn or
damaged, it must be replaced. See “How To
Replace the Friction Wheel” in this section. If the
friction wheel is not worn or damaged, check as
follows.
1. (Figure 1) Remove the gas from the gas
tank. Stand the snow thrower up on the front
end of the auger housing (4).
WARNING: Drain the gasoline out-
doors, away from fire or flame.
2. Disconnect the spark plug wire.
3. (Figure 22) Remove the bolts (1) on each
side of the bottom panel (2).
4. Loosen the bolts (3) on each side of the bot-
tom panel (2).
5. Remove the bottom panel (2).
6. (Figure 1) Position the shift speed lever (6)
in the lowest forward speed.
7. (Figure 24) Note the position of the friction
wheel (4). The correct distance “A” from the
right side of the friction wheel (4) to the out-
side of the motorbox is as follows:
Tire Size Distance “A”
12 and 13 inch 4-1/8” (10.5 cm.)
16 inch 4-5/16” (10.95 cm.)
If the friction wheel (4) is not in the correct
position, adjust as follows.

disc drive plate or the friction
wheel.
1. (Figure 1) Remove the gas from the gas
tank. Stand the snow thrower up on the front
end of the auger housing (4).
WARNING: Drain the gasoline out-
doors, away from fire or flame.
2. Disconnect the spark plug wire.

side of the bottom panel (2).
4. Loosen the bolts (3) on each side of the bot-
tom panel (2).
5. Remove the bottom panel (2).

7. (Figure 29) Use a 3/16” allen wrench and
remove the fastener that secures the right
axle clamp (30) to the axle (34).
8. Remove the right wheel (35), axle (34), axle
clamp (30), and washer (31).
9. (Figure 28) Remove the left wheel (10) from
the axle (11).
10.Remove the fasterners that secure the axle
suport (32) to the motorbox. Remove the
axle suport (32) and bushing (33).
11. Loosen (do not remove) the bolts that secure
the axle bearings (19) to the motor box.
12.Remove the clutch/drive sprocket assem-
bly (20) from the axle (11).
13.(Figure 30) Remove the four bolts (16) that
hold the bearings (7) on each side of the
hex shaft (8).
14.(Figure 31) Remove the hex shaft (8) and
bearings (7).
NOTE: Take special note of the position of
the washers (13) .
15.(Figure 26) Remove the three fasteners (4)
that hold the friction wheel (5) to the hub
(6).
16.(Figure 26) Remove the friction wheel (5)
from the hub (6). Slip the friction wheel (5)
off the hex shaft (8).
17.Assemble the new friction wheel (5) onto
hub (6) with the fasteners removed earlier.
18.(Figure 31)
Install the hex shaft (8) and
bearings (7) with the four bolts removed ear-
lier.
Make sure the washers (17) are properly
installed in the original position. Also,
make sure the two washers (13) are prop-
erly aligned with the actuator arms (14).

How To Replace the Auger Shear Bolt
The augers are secured to the auger shaft with
special shear bolts. These shear bolts are de-
signed to break and protect the machine if an
object becomes lodged in the auger housing.
Do not use a harder bolt as the protection pro-
vided by the shear bolt will be lost.
WARNING: For safety and to pro-
tect the machine, use only original
equipment shear bolts.
To replace a broken shear bolt, proceed as fol-
lows. Extra shear bolts were provided in the as-
sembly parts bag.
1. Stop the engine.
2. Disconnect the spark plug wire. Make sure
all moving parts have stopped.
3. (Figure 14) Lubricate the auger shaft Zerk
fitting (1), if equipped, with a grease gun.
4. (Figure 25) Align the hole in the auger with
the hole in the auger shaft. Install the new
shear bolt (2), spacer (3), and locknut (4).
NOTE: If the model has a 33” (84cm) Au-
ger Housing, the spacer (3) is not re-
quired.
5. Connect the spark plug wire.
How To Prepare The Snow Thrower For
Storage
WARNING: Do not remove gasoline
while inside a building, near a fire,
or while you smoke. Gasoline
fumes can cause an explosion or a fire.
If the snow thrower is to be stored for an ex-
tended period, refer to the engine manufactur-
er’s operating manual (included with some
models) for important maintenance or storage
details.
1. Drain the fuel tank.
2. Let the engine run until it is out of gasoline.
3. Never store the snow thrower with fuel in the
tank inside a building where ignition sources
are present such as hot water and space
heaters, clothes dryers, and the like. Allow
the engine (motor) to cool before storing in
any enclosure.
4. Drain the oil from the warm engine. Fill the
engine crankcase with new oil.
5. Remove the spark plug from the cylinder.
Pour one ounce of oil into the cylinder. Slow-
ly pull the recoil--start grip so that the oil will
protect the cylinder. Install a new spark plug
in the cylinder.
6. Thoroughly clean the snow thrower.
7. Lubricate all lubrication points. See the Main-
tenance section.
8. Be sure that all nuts, bolts and screws are
securely fastened. Inspect all visible moving
parts for damage, breakage and wear. Re-
place if necessary.
9. Cover the bare metal parts of the blower
housing, auger, and the impeller with spray
rust preventative lubricant.
10.Put the unit in a building that has good ven-
tilation.
11. If the machine must be stored outdoors,
block up the snow thrower to be sure the en-
tire machine is off the ground.
12.Cover the snow thrower with a suitable pro-
tective cover that does not retain moisture.
Do not use plastic.
