SECTION 7: SERVICING YOUR SNOW THROWER
Augers
The augers are secured to the spiral shaft with two
shear pins and cotter pins. If you hit a foreign object or
ice jam, the snow thrower is designed so that the pins
may shear. Refer to Figure 16.
If the augers do not turn, check if the pins have
sheared. Two 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 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.
• Remove the six carriage bolts and hex flange
locknuts which attach two skid shoes to the snow
thrower on two sides. See Figure 15.
• 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 hex flange locknuts which attach shave
plate to the snow thrower housing.See Figure 19.
• Reassemble the new shave plate, with heads of
carriage bolts to the inside of the housing. Tighten
securely.
Replacing Belts
• Disconnect the chute crank assembly at the
discharge chute end by removing the hairpin clip
and the flat washer.
• Remove the plastic belt cover, located near the
engine, by removing the three self-tapping screws
and flat washers that secure it. See Figure 19.
• Remove the large shoulder bolt and washer on the
left hand side of the engine pulley. See Figure 20.

Auger Belt
• Remove the hairpin clip and flat washer from the
ferrule in order to disconnect the auger idler rod
from the brake bracket assembly. See Figure 21.
• Slip the auger control belt (the front belt) off the
engine pulley. See Figure 21.
• Pull the brake bracket assembly towards the cable
guide roller and unhook the auger cable “Z” fitting.
• Remove the upper bolts and lock washers which
attach the auger housing assembly to the frame
assembly using a 9/16” wrench. Refer to Figure 19.
• Separate auger housing from the frame by tilting
the housing forward and pulling up the handles.
• Using a 1/2” wrench, remove the hex screw and
cupped washer from the center of the pulley on the
auger housing. Lift the brake bracket assembly out
of the pulley groove and remove the pulley. See
Figure 22. Be careful not to lose the key.
• Remove and replace auger belt inside belt keepers.
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.
