SECTION 6: SERVICING YOUR SNOW THROWER
WARNING:
Before servicing, repairing, or
inspecting, disengage all controls 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. Always wear
safety glasses during operation or while
performing any adjustments or repairs.
Augers
•
The augers are secured to the spiral shaft with six
shear pins and cotter pins. If you hit a hard foreign
object or ice jam, the snow thrower is designed so
that the pins may shear. Refer to Figure 15.
•
If the augers will not turn, check to see if the pins
have sheared. Replacement shear pins and cotter
pins have been provided with the snow thrower.
When replacing pins, spray an oil lubricant into
shaft before inserting new pins.
IMPORTANT:
NEVER replace the auger shear pins with
standard pins. 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.
•
Remove the carriage bolts and flange lock nuts
which attach the two skid shoes to the snow thrower
on two sides. See Figure 12.
•
Reassemble new skid shoes with the hardware
removed earlier. Make certain the skid shoes are
adjusted to be level.
•
To remove the shave plate, remove the carriage
bolts and flange lock nuts which attach the shave
plate to the snow thrower housing. See Figure 15.
Figure 15
•
Reassemble the new shave plate, with heads of
carriage bolts to the inside of the housing. Tighten
securely.
Belt Removal And Replacement
Auger Belts
NOTE:
It is necessary to remove both belts in order to
change either one. If changing just one belt, be certain
to check the condition of the other belt.
•
Disconnect the chute directional control at the
assembly base by removing the hairpin clip and the
flat washer. See Figure 16A.
Figure 16
•
Remove the plastic belt cover at the front of the
engine by removing the two self-tapping screws.
See Figure 16B.
•
Drain the gasoline from the snow thrower, or place
a piece of plastic film under the gas cap.
