How To Replace the Auger Shear Bolt

6.(Figure 25) Note the position of the friction wheel (4). The correct distance “A” from the 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)

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

How To Adjust The Friction Wheel

1.(Figure 1) Position the shift speed lever (6) in the lowest forward speed.

2.(Figure 9) Loosen the bolts (1) on the speed control rod (8).

3.(Figure 25) Move the friction wheel (4) to the correct position.

4.(Figure 9) Tighten the bolts (1) on the speed control rod (8).

5.(Figure 23) Install the bottom panel (2).

6.Tighten the 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.

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 29) Remove the fasteners that secure the left wheel (10). Remove the left wheel (10) from the axle (11).

4.Loosen the bolts (3) on each side of the bottom panel (2).

5.Remove the bottom panel (2).

6.(Figure 30) Remove the fasteners that secure the drive sprocket (12) to the axle (11).

7.Remove the right wheel, axle (11), and drive sprocket (12).

8.(Figure 31) Remove the four bolts (16) that hold the bearings (7) on each side of the hex shaft (8).

9.(Figure 32) Remove the hex shaft (8) and bearings (7).

NOTE: Take special note of the position of the washers (17).

10.(Figure 27) Remove the three fasteners (4) that hold the friction wheel (5) to the hub

(6).

11.(Figure 27) Remove the friction wheel (5) from the hub (6). Slip the friction wheel (5) off the hex shaft (8).

12.Assemble the new friction wheel (5) onto hub (6) with the fasteners removed earlier.

13.(Figure 32) Install the hex shaft (8) and bearings (7) with the four bolts removed earlier.

Make sure the washers (17) are properly installed in the original position. Also, make sure the two washers (13) are properly aligned with the actuator arms (14).

14.Make sure the hex shaft (8) turns freely.

15.(Figure 30) Install the right wheel, axle (11), and drive sprocket (12) with the fasteners removed earlier. Install the chain (15) onto the drive sprocket (12).

16.Check the adjustment of the friction wheel. See “How To Adjust The Friction Wheel” in this section.

17.Make sure the friction wheel and the disc drive plate are free from grease or oil.

18.(Figure 23) Install the bottom panel (2).

19.Tighten the bolts (3) on each side of the bottom panel (2).

20.Install the left wheel (10) to the axle (11) with the fasteners removed earlier.

21.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 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.(Figure 1) Move the stop switch (13) to the stop position. Disengage all controls.

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 26) Align the hole in the auger with the hole in the auger shaft. Install the new shear bolt (2), spacer (3), and locknut (4).

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.

en

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.Thoroughly clean the snow thrower.

6.Lubricate all lubrication points. See the Maintenance section.

7.Be sure that all nuts, bolts and screws are securely fastened. Inspect all visible moving parts for damage, breakage and wear. Replace if necessary.

8.Cover the bare metal parts of the blower housing, auger, and the impeller with spray rust preventative lubricant.

9.Put the unit in a building that has good ventilation. Store in a clean and dry area, but NOT near a stove, furnace or water heater which uses a pilot light or any device that can create a spark.

10.If the machine must be stored outdoors, block up the snow thrower to be sure the entire machine is off the ground.

11.Cover the snow thrower with a suitable protective cover that does not retain moisture. Do not use plastic.
