MAINTENANCE AND LUBRICATION
Gearcases
Middle Gearcase Lubrication
The middle gearcase fill plug (1) is
located on the right side of the middle
gearcase. The drain plug (2) is located
on the bottom side of the gearcase.
The middle gearcase lubricant level
should be checked every six months or
100 hours, whichever comes first.
Middle 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. Always use GL5 80-90
weight general lube.
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 grease
components. Always use GL5 80-90 weight general lube in the middle
gearcase.
Middle Gearcase Oil Changing Procedure
1. Support the vehicle securely with a
jackstand.
2. Remove the middle tire on the
driver’s side.
3. Remove fill plug (1).

oil. Catch and discard used oil
properly.

plug hole.
