How To Adjust Or Replace The Friction
Wheel
How To Check The Friction Wheel
If the snow thrower will not move forward, check
the traction drive belt, the traction drive cable or
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
outdoors, away from fire or flame.
2. Disconnect the spark plug wire.
3. (Figure 21) Remove the bolts (1) on each
side of the bottom panel (2).
4. Loosen the bolts (3) on each side of the
bottom panel (2).
5. Remove the bottom panel (2).

right side of the friction wheel (4) to the
outside 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)

How To Replace The Friction Wheel
If the friction wheel is worn or damaged, the
snow thrower will not move forward. The friction
wheel must be replaced as follows.
WARNING: Do not lubricate the
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
outdoors, away from fire or flame.
2. Disconnect the spark plug wire.
3. (Figure 27) Remove the bolts (1) on each
side of the bottom panel (2).
4. Loosen the bolts (3) on each side of the
bottom panel (2).
5. Remove the bottom panel (2).
6. (Figure 28) Remove the rear support brace
(18).
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 27) Remove the left wheel (10) from
the axle (11).
10. (Figure 30) 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
assembly (20) from the axle (11).
13. (Figure 31) Remove the four bolts (16) that
hold the bearings (7) on each side of the
hex shaft (8).
14. (Figure 32) Remove the hex shaft (8) and
bearings (7).
NOTE: Take special note of the position of
the washers (13).
15. (Figure 25) Remove the three fasteners (4)
that hold the friction wheel (5) to the hub
(6).
16. (Figure 25) Remove the friction wheel (5)
from the hub (6). Slip the friction wheel (5)

How To Replace the Auger Shear Bolt
The augers are secured to the auger shaft with
special shear bolts. These shear bolts are
designed to break and protect the machine if an
object becomes lodged in the auger housing. Do
not use a harder bolt as the protection provided
by the shear bolt will be lost.
WARNING: For safety and to
protect the machine, use only
original equipment shear bolts.
To replace a broken shear bolt, proceed as
follows. Extra shear bolts were provided in the
assembly parts bag.
1. Stop the engine.
2. Disconnect the spark plug wire. Make sure
all moving parts have stopped.
3. (Figure 13) Lubricate the auger shaft Zerk
fitting (1), if equipped, with a grease gun.
4. (Figure 24) 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" (84 cm)
Auger Housing, the spacer (3) is not
required.
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
extended period, refer to the engine
manufacturer'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.
Slowly 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
Maintenance section.
