Grease Fitting and Oil Point Lubrication

25 hours of operation. Use SAE general purpose lith-
ium or molybdenum base grease for grease fittings and
light machine oil (SAE 10) to lubricate oil points. Lubri-
cate the locations shown in the Snowblower Lubri-

PTO U-Joint

Lubricate the grease fitting for the PTO U-joint every 8
hours with SAE general purpose lithium or molybde-
num base grease.
The PTO U-joint is accessed by removing the gearbox
cover. Four (4) bolts fasten the gearbox cover to
mounting holes on the snowblower 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(s) and relubricate the gearbox as
follows:
1. Remove the gearbox following the procedure de-
scribed in Gearbox Replacement in REPLAC-
ING/REPAIRING.
