Gear Shaft
The gear (hex) shaft should be lubricated at least once
a season or after every 25 hours of operation.
1. Remove the lower frame cover by removing the two
screws which secure it.
2. Apply a light coating of an all-weather multi-purpose
grease to the hex shaft. See Figure 7.
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, the joystick should be lubricated with
petroleum jelly, linseed oil, mineral oil, paraffin wax or
3-in-1 oil.
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 8.
Gear Case
The auger gear case has been filled with grease at the
factory. If disassembled for any reason, lubricate with
two ounces of grease (Part Number 737-0168).
NOTE: Do not overfill the gear case. Damage to the
seals could result. Be sure the vent plug is free of
grease in order to relieve pressure.
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 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 9.
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.
Do not overfill the gear
case. Damage to the
seals could result.
