K-1. GENERAL
All
4-wheel-drive models are equipped with a
transfer
case to connect the power to the front
axle.
It is essentially a
two-speed
transmission
located at the
rear
of the standard transmission
and
provides a low and direct gear.

The
transfer case gears are controlled by the
driver

through
one shift lever.
Early
'Jeep'
Universal
Models with the F4-134
Hurricane
engine
are equipped with two transfer case shift control levers.

a.
On vehicles equipped with one transfer case

shift
lever, the transfer case shift lever has four
positions: 2WD
High,
4WD
High,
Neutral, and
4WD
low. The forward position of the lever 2WD

High
allows the
rear
wheels only to drive. The

first
rear
position (4WD High)
engages
the 4- wheel drive and provides high range 4-wheel drive.

The
second
rear
position (Neutral)
disengages
all power to the wheels and is used for stationary
power take-off operations. The last
rear
position
(4WD
Low) provides low range 4-wheel drive.

b.
On vehicles equipped with two transfer case

shift
levers, the transfer case front axle drive lever (left hand lever)
gives
a choice of 2-wheel or 4-
wheel drive. In the forward (out) position the
vehicle is in 2-wheel drive. Move the lever to the

rear
(in) position for 4-wheel drive operation.
The
4-wheel-drive
auxiliary-range
shift lever (right

hand
lever) has three positions; low, neutral, and
high.
The forward position (low)
gives
low-range
4-wheel drive. The center position (neutral) dis­
engages
all power to the wheels and is used for

stationary
power take-off operations. A built-in in­

terlock
prevents shifting into low range, 2-wheel
drive.
This
feature protects the
rear
axle from over­

load.
