and
Tube Assembly, which should be removed, and^trie latest

The
free pedal clearance is adjusted by lengthening
or shortening the" clutch fork cable. To make this adjustment,
loosen
the jam nut on the cable clevis

and
lengthen or shorten the cable to obtain %"

Clutch
Removal

When
necessary to remove the clutch,
follow
the procedures outlined in Section J for the removal
of the transmission and transfer case from the vehicle. Then remove the flywheel housing and use
the following procedures for removing the clutch assembly.

Note:
The F4
engine
may be removed from the
vehicle when inspecting or replacing the clutch.
Refer
to Section D for Hurricane F4
engine
re­moval and then
follow
the instructions given
below

to remove the clutch assembly.

a.
Mark
the clutch pressure plate and
engine
fly­
wheel with a center punch so the clutch assembly
may be installed in the same position after adjust­

ments
or replacement are completed.
b. Remove the clutch pressure plate bracket
bolts

equally, a little at a time, to prevent distortion and
to relieve the clutch springs evenly.
c. Remove the pressure plate assembly and driven
plate from the flywheel.

Clutch
Pressure Plate and Disc Inspection
Inspect the pressure plate face for
cracks,
chips,

and
warpage.
Check
the pressure plate levers for
excessive
wear and the springs for breaks. If any of the
above
conditions exist, the
complete
pressure
plate must be replaced.
Check
the clutch disc for

excessive
wear,
loose
or damaged facings, broken
vibration damper springs and evidence of grease
or oil. If any of the
above
conditions exist, replace
the clutch disc.

e.
Assemble ring gear on differential case with as­sembly

Adjustment
of
Differential
Side
Gears

Clearance
between
the differential side gears and differential case should be .000" to .006"
[0,000
a
0,192 mm.] Procedure for checking clearance is as
follows:

a.
With
the differential positioned as shown in

Fig.
N-31, tap the differential lightly on a flat
sur­
face so the differential gears
settle
into
proper
position.
b. Measure the clearance
between
side gears and
the case with leaf feeler
gauge
as illustrated. c. If the clearance
exceds
.006" add shims
between

the side gears and the case. To bring the clearance
within specified tolerance, shims in
these
thick­
nesses
are available.
.004"
[0,102
mm.], .006"
[0,152
mm.], .008"
[0,203

mm.].
If shims are required, at least one shim
should be placed on each side and the shim packs kept as even as possible. After adding shims, repeat
the clearance check.

Refer
to Fig. N-30.

The
adjustment of the differential bearings is main­
tained by the use of shims placed
betwen
the dif­
ferential case and the differential bearing. Proce­
dure for adjusting bearing preload is as follows:

a.
Install
the differential case and bearings in the
axle housing without shims and with the bearing
cups snug.
b. Holding the ring gear in contact with the pinipn

and
using a screwdriver blade to
move
the differen­

tial
bearing cups toward the center, insert feeler

gauge
on each side
between
differential bearing cup and the axle housing.
There
should be only
.001" to .002"
[0,025
a 0,051 mm.] backlash
remaining with the feeler
gauge
inserted.

c.
After the shim pack requirement for each bear­
ing has
been
established remove the differential
assembly. Make up shim packs and
keep
them separated.

d.
Add an additional .015"
[0,381
mm.] thickness:
of shims to the pack on the
tooth
side of the ring gear.

e.
Place the differential bearing shim packs on the
differential case under each bearing.
Install
bear­

ings
with
Driver
C-3716 for Model
27AF
axles
and
Driver
W-188 for Model 44 axles. See Fig. N-32.

Note:
When overhauling the Model
27AF
front
axle differential, check the axle inner oil seals. Should new seals be required, install them using
Tool
W-128 as shown in Fig. N-33. When installing
the axle differential in the axle housing, use
Spreader
Tool W-129.
f. Attach the
Carrier
Spreader W-129, (see
note

Par.
N-12) install a
dial
indicator, (Fig. N-19) and spread the
carrier
a maximum of .020"
[0,508

mm.].

h.
Lubricate bearings and place the differential in
the
carrier.

i.
Tap the unit carefully
into
place with
soft
mal­let, making sure the ring gear
teeth
mesh with the
pinion
teeth.

j.
Install bearing caps, matching their markings
with
those
on the
carrier.

k. Apply sealing compound to the screw threads.

Torque
the screws 70 to 90 lb-ft. [9,68 a 12,44
kg-m.].

I.
Install dial indicator to check ring gear back­
lash
(Fig. N-34). Check backlash at two points.

Backlash
must be held
between
.005" to .010"
[0,127
a
0,254
mm.]. If backlash
does
not fall with­

in
specifications, shims should be interchanged be­
tween
the two differential bearing shim packs until
correct backlash is obtained.

Note:
Changing the position of a .005"
[0,127
mm.]
shim from one side to the other
will
change the
amount of backlash approximately .003"
[0,076
mm.].

m. Check ring gear for runout. A reading in
excess

of .006"
[0,152
mm.] indicates a sprung differential
case, dirt
between
the case and the gear, or
loose

ring
gear screws.

n.
In order to assist in determining whether the
gears are properly adjusted, paint the bevel gear

teeth
with red lead or prussion blue and turn the
bevel gear so the pinion
will
make an impression on the
teeth.
The correct procedure to
follow
in the

event
of an unsatisfactory
tooth
contact is shown
in Fig.
N-35.
o. After the differential has
been
assembled and
adjusted, the pinion shaft oil seal should be in­
stalled.

GENERAL
Each
front wheel of a Jeep vehicle is carried on
two
opposed
tapered roller bearings as shown in

Fig.
Q-l and Q-2. Rear
wheels
are carried on a
single
tapered roller bearing
mounted
on each axle
shaft as shown in Fig. Q-3, Q-4 and Q-5. These bearings are adjustable for wear and their satis­
factory operation
depends
upon periodic
attention
and correct lubrication.

Q-4. Checking
Front
Wheel Bearings

Raise
the front end of the vehicle with a
jack

so that the tires clear the floor.

Grip
the tire and
test
sidewise shake of the wheel.

If
bearings are correctly adjusted, shake of the
wheel
will
be just perceptible and wheel
will
turn

freely with no drag.

If
bearing adjustment is too tight, the rollers may

break
or
become
overheated. Loose bearings may cause
excessive
wear and noise.

If
this
test
indicates bearing adjustment is neces­

sary,
follow
the procedure given in Par. Q-5. Loose
bearings
will
cause sidewise shake that is evident

around
the entire circumference of the wheel. A shake that is evident only when gripping the
wheels
in
a plane parallel to the ground, but not evident

around
the entire circumference, probably indicates
looseness
in the steering linkage.

Q-5.
Front Wheel Bearing Adjustment
With
the vehicle on the
jack,
the following proce­

dure
should be followed to adjust the front wheel
bearings on four wheel-drive vehicles.
a. Remove the hub cap, snap
ring,
capscrews, and
washers that attach the driving
flange
to the hub.

b.
Using the
Front
Axle Shaft Drive Flange Puller

W-163,
pull
the driving flange.
c. Bend the lip of the nut lock washer so that the

locknut
and lock washer may be removed.

d.
Rotate the wheel and tighten the adjustment nut until the wheel binds.

Note:
Front
tire and wheel must be rotated by

hand
as the adjusting nut is
tightened
to ensure positive seating of the bearing.

Then
back off the adjusting nut about one-sixth
turn
making sure that wheel rotates freely without
sidewise shake.
e. Replace the lock washers and locknut. Bend
over the lock washer lip.
f.
Check
the adjustment (Par. Q-4). Reassemble the driving
flange
and hub cap. Make certain the
gasket is properly installed
between
the hub and
the flange.

•
Model DJ-5, DJ-6

On
two-wheel drive vehicles, remove the hub cap
and
the wheel retaining nut cotter pin. Rotate the
wheel and tighten the wheel retaining nut until the wheel binds.
Then
back off nut about one-sixth
turn
or more if necessary making sure wheel ro­

tates
freely without sidewise shake. Replace the cotter pin and hub cap.

Q-6.
Rear
Wheel Bearing Adjustment —

Flanged
Axle Shaft

Vehicles
equipped with the
flange
type
rear
axle
shaft require no wheel bearing adjustment. The flanged axle shaft is equipped with a single row,

pre-adjusted,
tapered roller unit-bearing capable of
accepting thrust in either direction. The unit-

bearing
adjustment is built in at the factory mak­
ing shimming or bearing adjustment unnecessary.

Refer
to Fig. Q-6.

Q-7.
Checking
Rear
Wheel Bearings —
Tapered
Axle

Raise
wheel on which adjustment is to be made
by placing a
jack
under the axle housing.
With
hands,
test
sidewise shake and in and out play
of the wheel. If bearings are correctly adjusted,
shake of wheel
will
be just perceptible and the 337
