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 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 | |
16 inch |
If the friction wheel (4) is not in the correct position, adjust as follows.

6.Install the bolts (1) on each side of the bot- tom panel (2).
7.Tighten the bolts (1) and bolts (3) on each side of the bottom panel (2).
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 out- doors, away from fire or flame.
2.Disconnect the spark plug wire.
3.(Figure 28) 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.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 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).
19.Make sure the hex shaft (8) turns freely.
20.To install the remaining parts, reverse the above steps.
21.Check the adjustment of the friction wheel. See “How To Adjust The Friction Wheel” in this section.
22.Make sure the friction wheel and the disc drive plate are free from grease or oil.
23.(Figure 28) Install the bottom panel (2).
24.Install the bolts (1) on each side of the bot- tom panel (2).
25.Tighten the bolts (1) and bolts (3) on each side of the bottom panel (2).
26.Connect the spark plug wire.

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
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.
