MAINTENANCE AND LUBRICATION
Front Gearcase
Gearcase Lubrication
The front gearcase fill plug (1) is
located on the right side of the front
gearcase. The drain plug (2) is
located on the bottom side of the
gearcase.
The front gearcase lubricant level
should be checked every six months
or 100 hours, whichever comes first.
Front gearcase oil should be changed
annually.
With the RANGER on a level
surface, remove fill plug and check
the lubricant level. Lubricant should
be kept at the bottom thread of the
fill plug hole. The correct gearcase lubricant to use is Polaris premium
hub oil.
The oil should be changed according to the requirements in the
maintenance chart. If the machine is used in wet conditions the oil
should be checked more frequently. If the oil has a milky appearance it
should be changed as soon as possible. Failure to properly maintain
this important area can result in premature wear or possible failure of
the front grease components. Always use Polaris premium hub oil in
the front gearcase.
