LUBRICATION

LUBRICATION

WARNING

DO NOT attempt to lubricate the machine with the tractor engine running. Disengage the PTO clutch, shut off the ma- chine, and remove the ignition key.

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 every 25 hours of operation. Use SAE general purpose 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 molybdenum base grease.

The PTO U-joint is accessed by removing the gearbox 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 gearbox 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.
