Engine

Refer to the separate engine manual packed with your unit for all engine maintenance and lubrication instruc- tions.

Refer to Figure 6-1.

IMPORTANT: Keep all grease and oil off the rubber friction wheel and drive plate.

Wheels

At least once a season, remove wheels. Clean and coat the axles with a multipurpose automotive grease before reinstalling wheels.

Auger Shaft

At least once a season, remove the shear pins on auger shaft. Spray lubricant inside shaft, around the spacers. Also lubricate the flange bearings found at either end of the shaft. See Figure 6-2.

Augers

•The augers are secured to the spiral shaft with shear pins and cotter pins. If the auger should strike a foreign object or ice jam, the snow thrower is designed so that the pins may shear. See Figure 6-2.

•If the augers will not turn, check to see if the pins have sheared. Replacement shear pins have been provided with the snow thrower. When replacing pins, spray an oil lubricant into shaft before inserting new pins.

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. To remove skid shoes:

1.Remove the carriage bolts (and washers if equipped)and hex flange nuts which secure the skid shoes to the snow thrower.

2.Reassemble new skid shoes with previously removed hardware. Refer to Figure 6-3.

To remove shave plate:

1.Remove the carriage bolts and hex nuts which attach it and the skid shoes to the snow thrower housing.

2.Reassemble new shave plate, making sure heads of carriage bolts are to the inside of housing. 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.

1.Disconnect the chute crank assembly at the discharge chute end by removing the hairpin clip and the flat washer. See Figure 6-8.
