SECTION 6: MAINTAINING AND SERVICING YOUR SNOW THROWER
WARNING: Before lubricating, repairing, or
inspecting, disengage all controls and stop
engine. Wait until all moving parts have come
to a complete stop.
Engine
Refer to the separate engine manual packed with your
unit for all engine maintenance.
Lubrication
Engine
Refer to the separate engine manual packed with your
unit.
Gear Shaft
The gear (hex) shaft should be lubricated at least once
a season or after every 25 hours of operation.
• Remove the lower frame cover by removing the two
screws which secure it.
• Apply a light coating of an all-weather multi-
purpose grease to the hex shaft. See Figure 20.
Figure 20
IMPORTANT: Keep lubricant off the friction wheel and
drive plate.
Wheels
Oil or spray lubricant into bearings at wheels at least
once a season. Remove wheels, clean and coat axles
with a multi-purpose automotive grease.
Chute Directional Control
• Once a season, the spiral end on the chute
directional control should be greased with
multipurpose automotive grease.
Auger Shaft
• At least once a season, remove the shear pins on
auger shaft. Spray lubricant inside shaft, around
the spacers. Also lubricate the flange bearings
found at either end of the shaft. See Figure 21.
Figure 21- 30” Auger Shown
Augers
The augers are secured to the spiral shaft with shear
pins and cotter pins. See Figure 21. If you hit a foreign
object or ice jam, the snowthrower is designed so that
the shear pins will shear.
If the augers will not turn, check to see if the shear pins
have sheared. Replacements have been provided with
the snowthrower. When replacing pins, spray an oil
lubricant into shaft before ireassembling.
IMPORTANT: NEVER replace the auger shear pins with
anything other than OEM Part No. 738-04124 replacement
shear pins . Any damage to the auger gearbox or other
components as a result of failing to do so will NOT be
covered by your snow thrower’s warranty.
Gear Case
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.
Shave Plate and Skid Shoes
• 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.
