TO REPLACE FRICTION WHEEL
If the snow thrower will not move forward,
and the friction wheel is worn or damaged,
you need to replace it as follows: (First allow
the engine to cool).
• Drain the gasoline from the fuel tank by
removing the fuel line at the carburetor.
Drain the fuel in a container and reinstall
the fuel line.
CAUTION: Drain gasoline outdoor away
from fire or flame.
• Disconnect the spark plug wire.
• Stand the snow thrower up on the auger
housing end.
• Disconnect speed control rod from speed
rod by removing cotter pin (see figure
above). Keep trunnion in same position
on speed control rod. Movement of the
trunnion will result in speed changes.
Auger
• Remove right side bearing plate. Leave
hex shaft in original position.
• Remove friction wheel from hub. Slip fric­
tion wheel off hex shaft towards right
side.
• Position new friction wheel onto hub (see
first figure on page 22).
• Install bearing plates to original position.
Ensure hex shaft is engaged with both
bearing plates.
• Secure bearing plates, using bolts re­
moved earlier.
• Secure friction wheel to hub using fasten­
ers removed earlier. Ensure hex shaft
turns freely.
• Replace bracket to speed control lever.
• Reconnect speed control rod to speed
rod by reassembling the trunnion assem­
bly and cotter pin.
NOTE: Ensure friction wheel and friction
disc are free from grease or oil.
• Replace bottom panel.
• Lower the snow thrower onto the tires.
