Lubrication
Gear Shaft
The gear (hex) shaft should be lubricated at least once a season or after every 25
hours of operation.
1.
To prevent spillage, remove all fuel from tank by running engine until it
stops.
2.
Carefully pivot the snow thrower up and forward so that it rests on the auger
housing.
3.
Remove the lower frame cover from the underside of the snow thrower by
removing the self-tapping screws which secure it.
4.
Apply a light coating of engine oil (or 3-in-1 oil) to the hex shaft. See Figure
22.
NOTE: When lubricating the hex shaft, be careful not to get any oil on the aluminum
drive plate or rubber friction wheel. Doing so will hinder the snow thrower's drive
system. Wipe off any excess or spilled oil.
Wheels
At least once a season, remove both 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, and around the spacers and flange bearings found at either end of the shaft.
See Figure 23.
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.
To remove skid shoes:
1.
Remove the two carriage bolts, washers, and hex flange nuts that secure
each skid shoe to the snow thrower.
2.
Reassemble new skid shoes with the four carriage bolts (two on each side),
washers, and hex flange nuts. Refer to Figure 24.
To remove shave plate:
1.
Remove the carriage bolts and hex nuts which attach it to the snow thrower
housing.
2.
Reassemble new shave plate, making sure heads of carriage bolts are to the
inside of housing. Tighten securely. See Figure 24.
