GearShaft
The gear (hex) shaft should be lubricated at least once

screws which secure it.
• Apply a light coating of an all-weather multi-
purpose grease to the hex shaft. See Figure 5.
Figure 5
IMPORTANT: Keep lubricant off the friction wheel and
drive plate.
Wheels
• At least once a season, remove both wheels. Clean
and coat the axles with a multipurpose automotive
grease before reinstalling wheels.
ChuteDirectionalControl
• Once a season, the joystick should be lubricated
with petroleum jelly, linseed oil, mineral oil, paraffin
wax or 3-in-1 oil.

auger shaft. Spray lubricant inside shaft, around
the spacers. Also lubricate the flange bearings
found at either end of the shaft. See Figure 6.

GearCase
The auger gear case has been filled with grease at the
factory. If disassembled for any reason, lubricate with
two ounces of grease (Part Number 737-0168).
IMPORTANT:Do not overfill the gear case. Damage to
the seals could result. Be sure the vent plug is free of
grease in order to relieve pressure.
WARNING: Before servicing, repairing, or
inspecting, disengage all controls and stop
engine. Wait until all moving parts have come
to a complete stop.
ShavePlateandSkidShoes
• The shave plate and skid shoes on the bottom of
the snow thrower are subject to wear. They should
be checked periodically and replaced when
necessary.
• To remove skid shoes, remove the four carriage
bolts and hex flange nuts which secure them to the
snow thrower. Reassemble new skid shoes with the
four carriage bolts (two on each side) and hex
flange nuts. Refer to Figure 3.
• To remove shave plate, remove the carriage bolts
and hex nuts which attach it to the snow thrower
housing. Reassemble new shave plate, making
sure heads of carriage bolts are to the inside of
housing. Tighten securely.
