Changing Friction Wheel Rubber

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

•Tip the snow thrower up and forward, so that it rests on the housing.

•Remove screws from the frame cover underneath the snow thrower. See Figure 16.

•Remove the right wheel from the axle.

•Using a 3/4” wrench, hold the hex shaft and remove the hex bolts and cupped washer and bearing from left side of the frame. Refer to Figure 32.

•Holding the friction wheel assembly, slide the hex shaft out of the right side of the unit. The spacer on the left side of the hex shaft will fall and the sprocket should remain hanging lose in the chain.

•Lift the friction wheel assembly out between the axle shaft and the drive shaft assemblies.

•Remove four screws securing the friction wheel rubber between the friction wheel plates. See Figure 33. Discard old rubber.

•Reassemble the new friction wheel rubber to the friction wheel assembly, tightening the four screws

in rotation and with equal force. It is important to as- semble the rubber on the friction wheel symmetrically for proper functioning.

• Insert the pin from the shift arm assembly into the

friction wheel assembly and hold assembly in position.

Refer to Figure 34.

 

• Slide the hex shaft through the right side of the

 

housing and through the friction wheel assembly.

Figure 33

•Insert the hex shaft through the sprocket and the spacer. Make certain that the chain engages both the large and the small sprocket.

NOTE: If the sprocket fell from the snow thrower while removing the hex shaft, place the sprocket on the hex shaft. Position the hex hub of the sprocket toward the fric- tion wheel when sliding the sprocket on to the hex shaft.

•Slide the bearing onto the left end of the hex shaft and press into the hole on the left side the frame.

•Secure with the cupped washer and hex bolt removed earlier.

•Secure the frame cover with self-tapping screws. Put the snow thrower down to its normal operating position.

NOTE: If you placed plastic film under the gas cap, be certain to remove it.

WARNING

The rubber on the fric- tion wheel is subject to wear and should be checked after the first 25 hours of operation, and periodically thereafter. Replace the friction wheel rubber if any signs of wear or cracking are found.
