Lubrication
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 17.
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.
Engine
Refer to the separate engine manual packed with your
unit for all engine lubrication instructions.
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 18.
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).
Before reassembling, remove old sealant and apply new
sealant.
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.
Drive Mechanism
Remove rear cover. Oil any chains, sprockets, gears,
bearings, shafts, and shifting mechanism at least once
a season. Use engine oil or a spray lubricant. Avoid
getting oil on rubber friction wheel and aluminum drive
plate.

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 19.
Do not overfill the gear
case. Damage to the
seals could result.
