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.
