SECTION 8: SERVICING YOUR SNOW THROWER
WARNING: Before servicing, repairing,
or inspecting, disengage all clutch levers
and stop engine. Wait until all moving
parts have come to a complete stop.
Disconnect spark plug wire and ground it
against the engine to prevent unintended
starting.
Engine
Refer to the separate engine manual packed with your
unit for all engine maintenance procedures.
Augers
The augers are secured to the spiral shaft with two
shear bolts and hex lock nuts. If you hit a hard foreign
object or ice jam, the snow thrower is designed so that
the bolts may shear. Refer to Figure 19.
• If the augers will not turn, check to see if the bolts
have sheared. Replacement shear bolts and hex
lock nuts have been provided with the snow
thrower. When replacing bolts, spray an oil
lubricant into shaft before inserting new bolts.
IMPORTANT:
NEVER replace the auger shear bolts with
standard hex bolts. Any damage to the auger gearbox
or other components as a result of doing so will NOT be
covered by your snow thrower’s warranty.
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.
Figure 21
• To remove skid shoes, remove the four carriage
bolts, cupped washers and hex nuts which attach
them to the snow thrower. Reassemble new skid
shoes with the four carriage bolts, cupped washers
(cupped side goes against skid shoes) and hex
nuts. See Figure 21.
• To remove shave plate, remove the carriage bolts,
cupped washers 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.
Belt Removal and Replacement
Auger Belts
• Remove plastic belt cover from front of the engine
by removing the two self-tapping screws.
See Figure 22.
• Drain the gasoline from the snow thrower, or place
a piece of plastic film under the gas cap.
• Tip the snow thrower up and forward so that it rests
on its auger housing.
Figure 22
• Remove six self-tapping screws from the frame
cover underneath the snow thrower.
• Roll auger belt off the engine pulley. See Figure 23.
• Unhook the idler spring from the hex bolt on the
auger housing. See Figure 24.
• Unhook the support bracket spring from the frame.
NOTE: It may be necessary to loosen the six nuts that
connect the frame to the auger housing to aid in belt
removal.
