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: Deluxe skid shoes (on select models) have two wear edges. When one side wears out, they can be rotated 180° to use the other edge.

To remove skid shoes:

1.Remove the four carriage bolts and hex flange nuts which secure them to the snow thrower.

2.Reassemble new skid shoes with the four carriage bolts

(two on each side) and hex flange nuts. Refer to Figure 6-1.

NOTE: Augers not shown for clarity

Figure 6-1

To remove shave plate:

1.Remove the carriage bolts and hex nuts which attach it to the auger housing.

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

Lubrication

Gear Shaft

The gear (hex) shaft should be lubricated at least once a season or after every twenty-five (25) hours of operation.

1.Allow the engine to run until it is out of fuel.

2.Carefully pivot the snow thrower up and forward so that it rests on the auger housing.

3.Remove the frame cover from the underside of the snow thrower by removing the self-tapping screws which secure it. Refer to Figure 7-3 on page 19.

4.Apply a light coating of Anti-Sieze Regular Grade NS-42B to the hex shaft. See Figure 6-2.

Figure 6-2

NOTE: When lubricating the hex shaft, be careful not to get any anti-seize on the aluminum drive plate or the rubber friction wheel. Doing so will hinder the snow thrower’s drive system.

Auger Shaft

At least once a season, remove the shear pins from the auger shaft. Spray lubricant inside the shaft and around the spacers and the flange bearings found at either end of the shaft. See Figure 6-3.
