•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 6-12.

•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 6-13. 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 6-14 .

•Slide the hex shaft through the right 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.

NOTE: If the sprocket fell from the snow thrower while removing the hex shaft, align sprocket on chain, 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.

•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.
