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.
