SECTION 7: 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.
Augers
The augers are secured to the spiral shaft with two
shear bolts and hex lock nuts. If you hit a foreign object
or ice jam, the snow thrower is designed so that the
bolts may shear. See Figure 15.
If the augers do not turn, check if the bolts have
sheared. Two replacement shear bolts and hex lock
nuts have been provided with the snow thrower. Refer
to
Loose Parts on page 5.
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.
NOTE: The skid shoes on this machine have two wear
edges. When one side wears out, they can be rotated
180° to use the other edge.
Figure 15
• Remove the six carriage bolts (three per side), bell
washers and hex nuts which attach skid shoes to
the snow thrower on either side. See Figure 11.
• Reassemble new skid shoes with the hardware
removed earlier (cupped side of bell washer against
the skid shoes). Make certain the skid shoes are
adjusted to be level. Refer to Figure 11.
• To remove the shave plate, remove the carriage
bolts, bell washers and hex nuts which secure the
shave plate to the snow thrower housing. See
Figure 15.
• Reassemble the new shave plate, making sure
heads of carriage bolts are to the inside of the
housing.
Belt Replacement
WARNING: Disconnect the spark plug wire
from the spark plug and ground.
Auger Belts
NOTE: It is necessary to remove both auger belts in
order to change either one. If changing just one belt, be
certain to check the condition of the other belt.
• Remove the plastic belt cover on the front of the
engine by removing the two self-tapping screws.
See Figure 16.
• Drain the gasoline from the snow thrower, or place
a piece of plastic under the gas cap.
• Tip the snow thrower up and forward so that it rests
on the housing.
• Remove six self-tapping screws from the frame
cover underneath the snow thrower. See Figure 16
for the location of the hardware.
