GENERAL INFORMATION
GENERAL INFORMATION
The NV249 is an all the time, transfer case with
two operating ranges and a neutral position.
Operating ranges are 4-high and 4-low. The 4-low
range is used for extra pulling power in off road sit-
uations.
Engine torque is distributed to the front and rear
axles through a viscous coupling. The NV249 low
range is provided by a gear reduction system for
increased low speed, off road torque capability.
Shift Mechanism
Transfer case operating ranges are selected with a
floor mounted shift lever. The shift lever is connected
to the transfer case range lever by an adjustable
linkage rod. Range positions are marked on the
shifter bezel plate.
SHIFT MECHANISM
Transfer case operating ranges are selected with a
floor mounted shift lever. The shift lever is connected
to the transfer case range lever by an adjustable
linkage rod. Range positions are marked on the
shifter bezel plate.
TRANSFER CASE IDENTIFICATION
A circular I.D. tag is attached to the rear case of
each NV249 transfer case (Fig. 1). The tag provides
the transfer case model number, assembly number,
serial number and low range ratio.
The transfer case serial number also represents
the date of build.
RECOMMENDED LUBRICANT AND FILL LEVEL
Mopar Dexron II, or ATF Plus are the only lubri-
cants recommended for the NV249 transfer case.
Approximate fluid refill capacity is approximately
1.18 liters (2.50 pints).
Correct fill level is to the bottom edge of the fill
plug hole.
