Remove four screws securing the friction wheel to the 7.
hub assembly (refer to Figure 7-11). Discard old friction
wheel.
Reassemble the new friction wheel onto the hub assembly, 8.
tightening the four screws in rotation and with equal
force. It is important to assemble the friction wheel
symmetrically for proper functioning. Refer to Figure
7-11.
Reposition the friction wheel assembly in the snow 9.
thrower frame. Insert the pin from the shift arm
assembly into the friction wheel assembly and hold
assembly in position. Refer to Figure 7-12.
Slide the hex shaft through the right side of the frame 10.
toward the left side and through the friction wheel
assembly.
NOTE: If the sprocket fell from the snow thrower chain
while removing the hex shaft, position the hex hub of the
sprocket toward the friction wheel and place the sprocket
in the chain.
After making certain that the chain is on both the large 11.
and the small sprocket, align the hex shaft with the hex
hub of the small sprocket, and slide the shaft through
the sprocket.
