•
F4 and V-6 Engine.
Inspect the transmission main shaft pilot bushing
which
is pressed into the center of the flywheel on
the Hurricane F4
engine
and in the center of the
crankshaft
on the Dauntless V-6 engine. If the bushing is worn or damaged, it should be removed,
using a pilot bushing remover. Screw the tapered end of the tool into the damaged bushing, allowing
the tool to cut its own threads until a solid grip is obtained. Insert the puller screw and rotate it
until
bushing is forced out of flywheel, Fig. 1-6 or
crankshaft.
To
install a new bushing, slide the bushing
onto
the end of a pilot bushing installing and burnishing tool and insert the bushing into flywheel or
crank
shaft. A
soft
hammer can be used against the tool
to help drive the bushing in place. When the tool
is removed (by tightening the cap and pressure
nut as shown in Fig. 1-7), the bushing
will
be
burnished
to correct size. Apply a small amount of
lubricant
to the bushing bore.

DAUNTLESS
V-6
ENGINE
•
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

(Late
Models)
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

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.

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

with a fine file or
stone.
If the movement of the clutch driven
plate is not free on the splines, the result
will
be
