SECTION 7: SERVICING YOUR SNOW THROWER
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. Refer to Figure 13.
• 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 in the Assembly Section.
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. These 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 17
• Remove the six carriage bolts, belleville washers
and hex nuts which attach two skid shoes to the snow
thrower on two sides. See Figure 11.
• Reassemble new skid shoes with the hardware
removed earlier (cupped side of belleville washer
against the skid shoes). Make certain the skid shoes
are adjusted to be level.
• To remove the shave plate, remove the carriage
bolts, belleville washers and hex nuts which attach
the shave plate to the snow thrower housing.See
Figure 17.
• Reassemble the new shave plate, with heads of
carriage bolts to the inside of the housing. Tighten
securely.
Replacing Belts
To remove and replace either the auger belt or the drive
belt, follow the steps below and then proceed to the
specific steps listed under respective sub-headings.
• Disconnect the chute crank assembly at the
discharge chute end by removing the hairpin clip
and the two flat washers. See Figure 18A.
• Remove the engine shroud by removing the lock
nuts and bolts securing it. See Figure 18B.
• Remove the plastic belt cover, located near the
engine, by removing the three self-tapping screws
and flat washers that secure it. See Figure 18B.
Figure 18
• Tip the snow thrower up and forward so that it rests
on its auger housing. Refer to Figure 9.
• Remove the six self-tapping screws from the frame
cover underneath the snow thrower.
• Roll the front and rear auger belts off the auger drive
pulley. See Figure 19.
• Unhook the idler spring from the hex bolt on the
auger housing. See Figure 20.
• Back out the stop bolt until the support bracket rests
on the auger pulley.
NOTE: Loosening the six nuts that connect the frame to
the auger housing may aid in belt removal.
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.
