Maintenance Instructions
LUBRICATION
LUBRICATION
Proper lubrication is an important maintenance pro-
cedure. It reduces wear and makes the machine
quieter and easier to operate.
Grease Fitting and Oil Point Lubrication
Lubricate the grease fittings and oil points after ev-
ery 25 hours of operation. Use SAE general pur-
pose lithium or molybdenum base grease for grease
fittings and light machine oil (SAE 10) to lubricate oil
points. Lubricate the locations shown in the
Snowblower Lubrication Points illustration.
PTO U-Joint
Lubricate the grease fitting for the PTO U-joint every
8 hours with SAE general purpose lithium or molyb-
denum base grease.
The PTO U-joint is accessed by removing the gear-
box cover. Two (2) bolts (one on each side) fasten
the gearbox cover to mounting tabs on the snow-
blower frame (refer to Snowblower with Gearbox
Cover Removed photo).
Gearbox Lubrication
The gearbox is permanently lubricated (oil filled) and
sealed requiring no scheduled lubrication. However,
the gearbox oil seal(s) should be checked every 25
hours for indication of an oil leak. If an oil leak is
noted, replace the oil seal and relubricate the gear-
box as follows:
1. Remove the gearbox following the procedure
described in Gearbox Replacement in RE-
PLACING/REPAIRING.

2. Clean the area around the gearbox cover plate
to prevent contaminants from entering the gear-
case.
3. Remove the screws securing the cover plate on
the gearbox.
4. Check the level of lubricant in the gearbox. If
the lubricant is low, add SAE E.P. (Extreme
Pressure) 90W oil until the oil level is up to (sub-
merges) the horizontal shaft in the gearbox
(shaft parallel to cover plate).
NOTE: In case the gearbox is completely
drained of oil, approximately 5 fl. oz. (15 cl) of oil
is required to refill the gearbox.
IMPORTANT: DO NOT overfill the gearbox.
The gearbox assembly is not vented, and over-
filling with oil will cause excessive pressure and
result in oil leaks.
5. Check the condition of the cover gasket and
replace if worn or damaged. Reinstall gearbox
cover plate; torque screws to 24 in-lb (2.7 N·m).
6.
Reinstall the gearbox cover by reversing the re-
moval procedures.
WARNING
DO NOT attempt to lubricate the machine
with the tractor engine running. Disen-
gage the PTO clutch, shut off the ma-
chine, and remove the ignition key.
