MAINTENANCE

WARNING: Disconnect the spark plug

wire and ground against the engine

before performing any repairs or

maintenance.

AUGERS

The augers are secured to the spiral shaft with

two shear bolts and hex locknuts. See figure

21. A direct impact of an object will usually

cause the shear bolts to shear however, if you

ingest an object between the augers/impellers

and housing you may cause damage without

shearing bolts. Keep clear of foreign objects.

NOTE:

Locknuts cannot be threaded

onto a bolt by hand. This type of nut is

used where vibration occurs.

If the augers will not turn, check to see if the

hex bolts have sheared. Two replacement

shear bolts (M) and hex lock nuts (N) have

been provided with the snowthrower. When re-

placing bolts, spray an oil lubricant into shaft

before inserting new bolts.

SHAVE PLATE AND SLIDE SHOES

The shave plate and slide shoes on the bottom

of the snowthrower are subject to wear. They

should be checked periodically and replaced

when necessary.
To remove slide shoes, remove the four car-

riage bolts, Belleville washers and hex nuts

which attach them to the snowthrower. Reas-

semble new slide shoes with the four carriage

bolts, Belleville washers (cupped side goes

against slide shoes) and hex nuts.
To remove shave plate, remove the carriage

bolts, Belleville washers and hex nuts which at-

tach it and the slide shoes to the snowthrower

housing. Reassemble new shave plate, making

sure heads of the carriage bolts are to the in-

side of the housing. Tighten securely.

FRICTION WHEEL

Check wear on friction wheel at least once a

season. Replace rubber ring (friction wheel) be-

fore clamping plates damage aluminum drive

plate. See figures 18 and 26.

BELT REMOVAL AND REPLACEMENT

WARNING: Remove the spark plug

wire from the spark plug and

ground. Drain gasoline from the

fuel tank, or place a piece of plastic

film underneath the gas cap to pre-

vent gasoline from leaking.

• Disconnect chute crank assembly at the

discharge chute by removing the cotter

pin and flat washers. See figure 9.

• Remove the plastic belt cover on the front

of the engine by removing two self-tap-

ping screws. See figure 20.

AUGER DRIVE BELT:

• Unthread the bottom of the auger cable

from the “Z” fitting, leaving the hex nut in

place. See figure 5.

• Remove the six hex nuts, lockwashers and

hex nuts which attach the auger housing as-

sembly to the frame. See figure 21.

• Separate the housing from the frame as-

sembly by standing in the operating

position and lifting up on the handles.

The frame and housing will separate, and

the rear auger drive belt will come off the

pulleys. See figure 22.
