CLUTCH 1-1.
GENERAL

The
clutch on current 'Jeep' vehicles is either

Auburn
or Borg and Beck manufactured. Vehicles
equipped with F4-134
engines
have an
Auburn
9.25" [23,4 cm.] single plate dry-disc clutch. The
pressure plate has three coil pressure springs and
three levers or fingers.

The
V6-225
engine
is equipped with a 10.4" [26,4
cm.] Borg and Beck single plate dry-disc clutch.

The
pressure plate utilizes either a finger-type
diaphragm spring, or a coil
type
spring pressure plate for clutch release.

The
driven plates of all
models
are built with
vibra­

tion damper springs and have two flexible facings

which
provide
smooth
engagement
of the
engine
power.
Early
'Jeep' vehicles equipped with a Dauntless
V-6
engine
use a 10.4" [26,4 cm.] single plate, dry-
disc clutch, incorporating a diaphram-type spring assembly.

The
clutch is of the centrifugal single dry disc
type
and
consists of the clutch disc, pressure plate and
the clutch release bearing.

The
clutch is actuated by a clutch pedal and a
series of mechanical linkage.

When
the clutch pedal is in the
engaged
position,
the clutch disc facings are clamped
between
the
friction surface of the
engine
flywheel and the face of the clutch pressure plate, thereby connect­
ing
engine
power to the transmission. Depressing
the clutch pedal actuates the clutch release shaft
fork
which
moves
the clutch release bearing against
the clutch fingers.
This,
in
turn,
moves
the pressure
plate away from the clutch disc. Since the disc is splined to the transmission input shaft, the clutch
disc and transmission input shaft
will
stop
when
the clutch is disengaged, thereby disconnecting
engine
power from the transmission.
1-2.
Clutch
Maintenance

To
obtain normal life and satisfactory performance
from any clutch it must be correctly operated and
properly maintained. Two conditions which shorten
clutch life are continuous operation of the clutch
release bearing and clutch slippage.
The
clutch release bearing is
designed
for inter­
mittent use. If run continuously the bearing
lubri­

cant
will
become
exhausted causing the bearing to
become
dry, noisy, or
will
seize, resulting in clutch
finger or diaphragm wear. The clutch must be properly adjusted so that the release bearing is
free of the clutch fingers or diaphragm at all times,

except
when the clutch pedal is depressed.

Excessive
clutch slippage
often
occurs when the
vehicle is overloaded, the vehicle load is applied
too quickly, or when the pressure of the clutch fingers or diaphragm is only partially applied to the clutch plate.
Friction
between
the clutch facing

and
flywheel produces
excessive
heat causing
burned,
glazed and worn linings, resulting in shortened clutch life. Avoid clutch slippage under
heavy loads by using a lower gear or reducing the load.
1-3.
Clutch
Pedal
Linkage
and Adjustment

Adjust
the clutch pedal free travel whenever the clutch
does
not
disengage
properly, or when new
clutch parts are installed. Improper adjustment of
the clutch pedal free travel is one of the
most
fre­
quent causes of clutch failure and can be a con­ tributing factor in
some
transmission failures.

As
the clutch facings wear the free travel of the clutch pedal diminishes. When sufficient wear oc­

curs
the pedal clearance must be adjusted.

Two
types
of clutch linkage have
been
used on Jeep vehicles, a cross shaft
tube
and lever
type

shown in Fig. 1-1, and a clutch control cable
type

shown in Fig. 1-2. The clutch pedal adjustment
procedures for both
type
linkages are as follows.
•
Cross

Note:
Two different

and

Tube
Assemblies have
been

Should difficulty in shifting the transmission be
noted, check the length of the clutch release pedal
rod,
item (16) in Fig. 1-1. Measure the distance

between
the centerlines of the cotter key holes.

Diaphragm Spring Type
(Early
Models)

*
Jeep' vehicles equipped with a Dauntless V-6 en­
gine
use a 10.4" [26,4 cm.] single-plate, dry-disc

clutch,
incorporating a diaphragm-type spring as­
sembly.

When
the clutch pedal is depressed, it
moves
the
clutch
fork in the direction shown in Fig. 1-8. The

clutch
fork, pivoting on a
ball
stud, acts upon the
throwout bearing. The bearing then forces the
prongs of the diaphragm spring in the direction shown in
Fig.
1-8. The diaphragm spring is mounted
so that it pivots on its retaining rings.
This
reverses
the direction of force.
Force
is applied directly to
the three retracting springs which then
move
the
pressure plate
rearward,
away from the driven plate.

The
clutch driven plate assembly slides freely on
the transmission main drive gear splined shaft. It is keyed to the gear shaft by ten splines. The
front end of the main drive gear shaft is piloted by a bushing pressed into a recess in the
rear
end
of the
engine
crankshaft. See Fig. 1-8.

The
outer area of the driven plate is divided into

segments
formed in low waves to provide springs

between
the plate facings and cushion
engagement

of the clutch. A molded facing is riveted to each
side of every
segment.
When the clutch is fully
released, the waved
segments
cause the facings to

spread
approximately .045" [1,14 mm.]. Pressure
plate movement provides an additional clearance
of approximately .030" [0.76 mm.] to assure
full
release of the driven plate. See Fig. 1-8.

The
driven plate assembly is designed to prevent
torsional fluctuation of the
engine
from being
transmitted to the transmission gears. Its hub is

a.
Remove transmission as described in Section J. b. Remove clutch throwout bearing and pedal re­

turn
spring from clutch fork.
c. Remove flvwheel housing from engine.
d.
Disconnect clutch fork from
ball
stud by forc­
ing it toward the center of the vehicle.
e.
Mark
clutch cover and flywheel with a center

punch
so that cover can later be installed in the same position on the flywheel.
This
is necessary to

maintain
engine
balance.
f. Loosen the clutch attaching
bolts
alternately,
one
turn
at a time, to avoid distorting the clutch
cover flange, until diaphragm spring is released.
g. Support the pressure plate and cover assembly
while removing last bolts; remove pressure plate
and
driven plate from flywheel.

Caution:
Use extreme care to keep clutch driven plate clean.

h.
If it is necessary to disassemble pressure plate,
remove three drive strap-to-pressure plate
bolts
and
retracting springs. Remove pressure plate from

clutch
cover.

Note:
When disassembling,
note
position of
grooves

on
edge
of pressure plate and cover. These marks must be aligned in assembly to maintain balance.

i.
The clutch diaphragm spring and two pivot rings

are
riveted to the clutch cover. Inspect spring, rings

and
cover for excessive wear or damage. If there
is a
defect,
replace the complete cover assembly.

Clutch
inspection

Wash
all metal parts of clutch, except release bear­
ing and driven plate, in suitable cleaning solution to remove
dirt
and grease. If solvent
seeps
into

bearing,
lubricant may be dissolved. Cleaning sol­
vent
will
also damage the facings of driven plate,
a.
Inspect friction surfaces of flywheel and pres­

sure
plate for scoring or roughness. Slight roughness
may be smoothed with fine emery cloth. If surface 229

CLUTCH

is deeply scored or grooved, the part should be

replaced.

b. Inspect driven plate for wear or damage to fac­
ings,
loose
rivets, broken or
loose
torsion springs,

and
flattened cushion springs. If facings are worn
near
rivets or are oily, replace the plate assembly.

A
slight amount of oil on clutch facings
will
cause

clutch
grab and chatter; excessive oil on facings

will
cause slippage. It is not practical to remove
oil
with solvents or by buffing since oil
will
con­
tinue to bleed from facing material when hot. If
oil
is found on driven plate facings, examine trans­
mission drainback hole, pilot bushing,
engine
rear

main
bearing and other points of possible oil leakage. Test the fit of driven plate hub on trans­
mission main drive gear for an easy sliding fit.
c. Inspect clutch release bearing for scoring or ex­ cessive wear on front contact face. Test for rough­

ness
of balls and races by pressing and turning
front race slowly. Inspect main drive gear pilot
bushing in crankshaft. Replace bushing if it is rough or worn. Regardless of whether the old plate

or
a new plate is to be installed, check the plate
for runout. Slide the driven plate, front side first,
over the transmission main drive gear shaft so that

it
is tight on the spline. Index a
dial
indicator to the plate facing as shown in
Fig.
1-9. While holding

firmly
against front end of main drive gear, to take up play in main drive gear bearing, slowly
rotate driven plate and observe the amount of
run­

out shown by indicator. If runout of front facing
exceeds
.025" [0,635 mm.], replace the plate. It
is not practical to correct excessive runout by bending. 12769

The
Borg & Beck clutch is a single plate, dry disk
type. It provides smooth
engagement
of
engine
power to the wheels. The clutch consists of a pres­

sure
plate assembly with pressure springs and
release levers, and driven plate assembly. The
driven
plate assembly
uses
spring center vibration
neutralizes and two flexible facings.

The
clutch driven plate is spring cushioned with a facing riveted to both sides. The coil springs around
the hub absorb the power shocks and cushion the

driving
mechanism. The clutch throw-out bearing is of the
ball
type, packed at time of manufacture,

and
requires no further lubrication.
No adjustment for wear is provided in the clutch itself. An individual adjustment is built into the
clutch
cover to adjust the height of the release
levers.
This
adjusting nut is locked in position

and
should never be disturbed unless the clutch assembly has been disassembled for the replace­
ment of worn parts or to correct the height of the release levers.

When
the clutch pedal is depressed (disengaged),
the release bearing is moved toward the flywheel
and
contacts the inner ends of the release levers.

Each
lever is pivoted on a floating pin which re­
mains stationary in the lever and rolls across a short flat portion of the enlarged
hole
in the eye-
bolt. The outer ends of the
eyebolts
extend
through
holes
in the stamped cover and are fitted

with
adjusting nuts to secure the levers in the
correct
position. The outer ends of the release levers

engage
the pressure plate lugs by means of ful-
crums,
which provide knife-edge contact
between

the outer ends of the levers and the lugs as shown
in
