Changing Bonded Friction Wheel

•Replace belt and reassemble in reverse order.

•Reassemble the two halves of the unit hooking the lower portion of the auger housing over the stationary shoulder bolts in the frame assembly.

•Secure the two halves with the two bolts and lock washers removed earlier. Refer to Figure 18.

•Attach the “Z” fitting of the cable into the brake bracket assembly. Refer to Figure 20.

•Slip the auger control belt over engine pulley.

•Insert ferrule on auger idler rod into bracket assembly and secure with flat washer and cotter pin. Reassemble the large shoulder bolt and lock washer as shown in Figure 19.

•Reassemble belt cover and chute crank.

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

•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 six screws from the frame cover underneath the snow thrower.

•Remove the left wheel from the axle.

•Using a 7/8” wrench, hold the hex shaft and remove the hex bolts and bell washer and bearing from left side of the frame. See Figure 23A.

•Holding the friction wheel assembly, slide the hex shaft out of the left side of the unit. The spacer on the right 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 assembly together. See Figure 23B.

•Discard old bonded friction wheel.

•Reassemble the new bonded friction wheel to the friction wheel assembly, tightening the four screws in rotation and with equal force.

•Insert the pin from the shift arm assembly into the friction wheel assembly and hold assembly in position. See Figure 23A.

•Slide the hex shaft through the left side of the housing and through the friction wheel assembly.

•Insert the hex shaft through the sprocket and the spacer. Make certain that the chain engages both the large and the small sprocket. See Figure 24.

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 friction wheel when sliding the sprocket on to the hex shaft. See Figure 24.

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

•Secure the frame cover with six 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.
