Inspect
Pressure Plate and Disc
Inspect the pressure plate to make sure that it is not cracked or scored.
Check
on a surface plate
for a warped condition, as a pressure plate out of alignment
will
result in clutch chatter.
Machin
ing or grinding the face of a warped pressure
plate is not recommended. If a warped condition
exists, replace the pressure plate. A new plate
should be installed if the plate or cushion springs appear to be defective. The cushion springs must
not be bent out of shape or flattened.
The
clutch discs for the nine or twelve spring clutches are designed for operation with their
respective clutches. Difference in general appear ance of the discs may be noted in the method of
housing the six torque dampening springs and in the
hub design.
After
removal of the clutch assembly, the disc should be inspected. The presence of grease or oil
on the friction facing can cause the clutch to chatter
and
grab during
engagement
and slip at higher speeds. If this condition is evident, the facings or
disc should be replaced and the cause of oil ac
cumulation corrected. Excessively worn facings
should be replaced. The clutch disc must be in stalled with the long end of the hub toward the
transmission.
1-20.
Inspect Transmission Clutch
Shaft
Slide
the clutch driven plate
onto
the transmission
clutch
shaft to make sure that it is free on the
splines. If the splines on the transmission clutch
shaft are
burred,
remove the
burrs
with a fine file or
stone.
If the movement of the clutch driven
plate is not free on the splines, the result
will
be
clutch
drag and
hard
shifting of transmission gears.

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.
K-2.
Removal of
Transfer
Case
The
transfer case may be removed from the vehicle
without removing the transmission. Where both
transmission
and transfer case are to be removed
together,
refer to Section J. To remove only the
transfer
case from the vehicle, proceed as follows:
a.
Drain
transmission
and transfer case and replace
drain
plugs.
b.
Disconnect the brake cable.
c.
Disconnect front and
rear
propeller shafts at
the transfer case. See "Propeller Shafts and
Uni
versal
Joints."
d.
Disconnect
speedometer
cable at transfer case. e. Disconnect the transfer case shift levers. On
vehicles equipped with two shift levers
loosen
set screw and remove pivot pin. Use a screw
driver
to pry shift lever springs away from shift levers.
Lift
levers from transfer case. On models equipped
with
a single shift lever remove pivot pin cotter
key,
and the adjusting rod attaching nut to remove
shift
lever. See Fig. K-4.
f. Remove cover plate on
rear
face of transfer case.
Remove
cotter key, nut and washer from trans
mission
main shaft.
g. If possible, at this point remove the transfer case main drive gear from the transmission main
shaft.
If not possible, see
step
j below.
h.
Remove transfer case torque reaction support
bracket
bolt and nut.
i.
Remove transmission to transfer case bolts.
j.
Remove transfer case. If the transfer case main
drive
gear has not been removed in
step
g above,
proceed as follows:
Brace
the end of the trans
mission
main shaft so that it cannot
move
in the
transmission,
pull
the transfer case to the

checked, making sure it is clean and open.
The
front wheel bearings should be checked every
12,000
miles. Refer to Section Q. Front wheel toe-
in
is adjustable by lengthening or shortening the
tie rod. However, standard caster and camber of
the front
wheels
are built
into
the axle. Wheel
caster can be adjusted by placing tapered shim
plates or
wedges
between
the springs and spring
seats
welded to the axle housing. Steering
geometry
and
front wheel adjustments are discussed in Sec tion O.
The
axle housing should be checked periodically
for weld cracks and/or other damage that may cause misalignment of the front
wheels
or
loss
of lubricant. The spring clips (U-bolts) should be
inspected and torqued every
12,000
miles. Torque (spring clip) nuts 45 to 50 lb-ft. [6,2 a 6,9 kg-m.].

2-WHEEL-DRIVE
FRONT
AXLE
The
front axle is of the reverse
Elliot
type. It is a
steel forging, heat treated for strength and ma
chined
to
close
limits. The steering knuckles are
mounted on pins which pass through
openings
at each end of the
"I"
beam and are locked securely
in
position with tapered pins and nuts. The knuckles
ride
on
ball
thrust bearings for
ease
of steering. See
Figs.
M-12, M-13.
The
knuckles are connected by a tie rod which is
mounted on
ball
and socket connections. The tie
rod
is adjustable to secure correct
toe-in
of the front wheels. A steering connecting rod
connects
the
left
knuckle arm with the steering gear arm.
Standard
caster and camber of the front
wheels
are
built
into
the front axle. Wheel camber cannot
be changed however, caster can be adjusted by
placing
tapered shims or
wedges
between
the
springs and spring seats. For
complete
information
regarding
the steering
geometry
refer to the
Section O.
M-16.
Removal of Solid
Front
Axle

The procedure for removing the solid front
axle varies slightly, depending on whether the
springs are slung under or over the axle. These
variations
are
noted
in the following procedure.
a. -
Raise the front end of the vehicle and safely support the frame behind the springs.
b.
Remove the
wheels
by removing the wheel
discs and lug nuts.
c.
Disconnect the steering connecting rod at the
ball
and socket connection on the steering knuckle. 282
