Bolens 933 SWE Snow Blower User Manual


 
Slide the shave plate out of the off-set slot at the
bottom of the housing, and from between the skid
shoes and side panels of the housing.
With the mounting holes toward the back, slide the
new shave plate into position and secure with the
fasteners removed previously.
Lubrication
Gear Shaft
The gear (hex) shaft should be lubricated at least once a
season or after every twenty-five (25) hours of operation.
Carefully pivot the snow thrower up and forward so
that it rests on the auger housing.
Remove the frame cover from the underside of the
snow thrower by removing four self-tapping screws
which secure it. Refer to Figure 6-6.
Apply a light coating of engine oil (or 3-in-1 oil) to the
hex shaft. See Fig. 6-2.
NOTE: When lubricating the hex shaft, be careful not to get
any oil on the aluminum drive plate or the 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.
Chute Directional Control
Once a season, lubricate the eye-bolt bushing and the
spiral with 3-in-1 oil.

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.

When one side wears out, they can be rotated 180° to use the
other edge.
To Remove skid shoes:
Remove the six carriage bolts, hex nuts, and bell
washers that secure the two skid shoes to the sides of
the auger housing. Refer to Figure 6-1.
Position the new skid shoes and secure with the
carriage bolts, bell washers, and hex nuts. Make
certain the skid shoes are adjusted to be level. Refer
to Fig. 6-1.
To replace shave plate:
Remove the hex nuts, bell washers, and carriage bolts
that secure the shave plate to the bottom of the snow
thrower housing.
Remove the rear most hex nut, bell washer, and
carriage bolt securing the back of each skid shoe to
the sides of the housing. Loosen the remaining hex
nuts securing the skid shoes.
