Friction Wheel Removal

If the snow thrower fails to drive with the drive control engaged, and performing the drive control cable adjust- ment on page 12 fails to correct the problem, the friction wheel may need to be replaced. Follow the instructions below. Examine the friction wheel for signs of wear or cracking and replace if necessary.

•Place the shift lever in third Forward (F3) position.

•Drain the gasoline from the snow thrower, or place a piece of plastic under the gas cap.

•Carefully pivot the snow thrower up and forward so that it rests on the auger housing.

1.a. Remove the frame cover from the underside of the snow thrower by removing four self-tapping screws which secure it. See Figure 6-13.

b.Remove the right-hand wheel by removing the screw and cupped washer which secure it to the axle.

2.Carefully remove the hex nut and washer which secures the hex shaft to the snow thrower frame and lightly tap the shaft’s end to dislodge the ball bearing from the right side of the frame. See Figure 6-14.

3.Carefully position the hex shaft downward and to the left before carefully sliding the friction wheel assembly off the shaft. See Figure 6-15.

NOTE: If you’re replacing the friction wheel assembly as a whole, discard the worn part and slide the new part onto the hex shaft. Follow the steps above in reverse order to reassemble components. If you’re disassem- bling the friction wheel and replacing only the rubber ring, proceed as follows:

4.Remove the four screws which secure the friction wheel’s side plates together. See Figure 6-16.

•Remove the rubber ring from between the plates.

•Reassemble the side plates with a new rubber ring.

•Slide the friction wheel assembly back onto the hex shaft and follow the steps above in reverse order to reassemble components.

Maintaining

Your Snow

Thrower

When reassembling the friction wheel as- sembly, tighten each screw only one rota- tion before turning the wheel clockwise and proceeding with the next screw. Repeat this process several times to ensure the plates are secured with equal force.

NEVER replace the auger shear pins with standard hex pins. Any damage to the auger gearbox or other components as a result of failing to do so will NOT be covered by your snow thrower’s warranty.
