• Reassemble the new friction wheel rubber to the
friction wheel assembly, tightening the six screws in
rotation and with equal force. It is important to
assemble 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. See Figure 21.
• 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.
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 22.
• 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.
