Gearcase Lubrication
OIL VISCOSITY
Choose the viscosity according to the temperature as shown in the appropriate oil viscosity chart
(Figure 27)
.
See
following NOTE.
NOTE:
Use engine oil with API classification CF for diesel engines.
Using multi-grade oils (5W-20, 10W-30, and 10W-40) will increase oil consumption. If multi-grade oil is used, check the
oil level more frequently.

GEARCASE LUBRICATION
NOTE:
Dispose of used oil according to the environmental laws and regulations for your area.
LUBRICATION LEVEL CHECK FOR FRONT DIFFERENTIAL, TRANSMISSION, AND REAR
DIFFERENTIAL
Each gearcase component is equipped with two oil port plugs (1 and 2)
(Figure 28, Figure 29, and Figure 30)
. When
the vehicle is on a level surface, use the level indicator hole (upper plug) (1) in the front differential and the transmission
as a lubricant level indicator. Lubricant level should be even with the bottom of level indicator hole (1).
NOTE:
Do not use the fill hole in the rear differential as a lubricant level indicator.
LUBRICATION CHANGE FOR FRONT DIFFERENTIAL, TRANSMISSION, AND REAR
DIFFERENTIAL
NOTE:
Metal particles may be discovered in the fluid or on the magnetic drain plug when changing the differential or
transmission fluid. These particles are normal and expected for the first few fluid changes. This is a result
of the gears being “net forged”, meaning the gears are forged to a shape very close to the final gear size
but the teeth are not finish machined prior to assembly. The “finish machining” occurs when the gears make
contact under load during vehicle operation. The magnetic drain plug is included in the design to collect
the metal particles generated from the gear break in process. This is an established process and is not
detrimental to gear service life.
Dispose of used oil according to the environmental laws and regulations for your area.
Use the lower plug (2) for drainage
(Figure 28, Figure 29, or Figure 30)
. Remove both plugs to allow the lubricant to
drain faster.
