SECTION 9: LUBRICATION
WARNING: Disconnect the spark
plug wire and ground against the
engine before performing any repairs
or maintenance.

ENGINE

Refer to engine manual for engine lubrication
instructions.
WARNING: When following instruc-
tions in separate engine manual for
draining oil, be sure to protect frame to
avoid oil dripping onto transmission parts.

WHEELS

Oil or spray lubricant into bearings at wheels at
least once a season. Pull klick pin, remove wheels,
clean and coat axles with a multipurpose
automotive grease. See Figure 23.
Figure 23

CHUTE CRANK

The worm gear on the chute direction crank should
be greased with multipurpose automotive grease.

AUGER SHAFT

Remove shear bolts on auger shaft. Oil or spray
lubricant inside shaft. See Figure 24.
Figure 24

GEAR SHAFT

Lubricate the gear shaft with a good al-weather
multi-purpose light grease at least once a season or
after every 25 hours of operation.
IMPORTANT: Keep all grease and oil off of the
friction wheel and drive plate.

DRIVE AND SHIFTING 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.

GEAR CASE

The worm gear case has been filled with grease at
the factory. If disassembled for any reason,
lubricate with 2 ounces of Shell Alvania grease
EPR00, part number 737-0168. Before
reassembling, remove old sealant and apply “Loctite
5699” or equivalent.
IMPORTANT: 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.
SECTION 10: MAINTENANCE
WARNING: Disconnect the spark
plug wire and ground against the
engine before performing any repairs
or maintenance.

ENGINE

Refer to separate engine manual for all engine
maintenance procedures.

AUGERS

The augers are secured to the spiral shaft with two
shear bolts and hex lock nuts. See Figure 24. If you
hit a foreign object or ice jam, the snow thrower is
designed so that the bolts will shear.
If the augers will not turn, check to see if the bolts
have sheared. A replacement shear bolt (P) and
hex lock nut (Q) have been provided with the snow
thrower. When replacing bolts, spray an oil lubricant
into shaft before inserting new bolts.

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.
