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. See Figure 16. If you hit
a foreign object or ice jam, the snow thrower is
designed so that the bolts may shear.
Figure 16
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. For future use, order the
parts numbers listed in Figure 1.
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.
•
Remove the six carriage bolts (three per side),
belleville washers and hex nuts which attach slide
shoes to the snow thrower on two sides. See Figure 8
on page 7.
•
Reassemble new slide shoes with the hardware
removed earlier (cupped side of belleville washer
against the slide shoes). Make certain the slide
shoes are adjusted to be level.
•
To remove the shave plate, remove slide shoe as
well as the carriage bolts, belleville washers and
hex nuts which attach shave plate to the snow
thrower housing. For location of shave plate and
carriage bolts, see Figure 16.
•
Reassemble the new shave plate, making sure
heads of carriage bolts are to the inside of the
housing.
•
Reinstall the skid shoes and 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.
