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 (a) and hex flange nuts (b)
which secure them to the snow thrower.
2. Reassemble new skid shoes with the four carriage bolts (a)
(two on each side) and hex flange nuts (b).
Refer to Figure 6-1.

To remove shave plate:
1. Remove the carriage bolts (c) and hex nuts (d) 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 7-4 on page 20.
4. Apply a light coating of Bostik Regular Grade Never-Seez®
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 (a) and cotter pins
(b) 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.
