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

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
Fig.

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.

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.

GENERAL
A
three speed synchromesh transmission is standard
equipment on all 'Jeep' Universal vehicles.
The
models T90 and T96 transmissions are used

with
the
Hurricane
F4 engine, and models
T86AA
and
T14A transmissions are used with the Daunt­
less
V-6 engine. All model transmissions are similar

in
design with exception of the T14A which is a

fully
synchronized (all forward gears) transmission

with
helical drive gears throughout.
The
transmission assembly is attached to the
rear

face of the flywheel bell housing and is supported on a rubber insulator at the frame center cross member which forms the
rear
engine
support.

All
4-wheel-drive vehicles are equipped with a
transfer
case attached to the
rear
of the trans­mission.
Transfer
case service and repair procedures

are
described in Section
K.

Models
CJ-5A,
and
CJ-6A
are equipped with the
same transmission, but with a remote control shift.
Models DJ-5 and DJ-6 are equipped with a similar

transmission,
however, the construction is
some­
what different because it is not designed to receive a transfer case for four-wheel drive.

For
DJ-5 and DJ-6 2WD vehicles, the trans­ mission repair procedures begin with Par. J-12.
J-2.
TRANSMISSION SHIFTING CONTROL
The
shift of the three-speed transmission is smooth

and
positive. The cane control lever shifts the trans­
mission gears direct from the shift control housing
mounted to the top side of the transmission housing.

The
remote control lever shifts the transmission
gears through remote control rods attached to the

adjusting
levers of the shift shafts protruding from the left side of the transmission housing. Poppet
balls and springs retain the transmission gears in mesh and an interlocking mechanism prevents
shifting into two gears at the same time.
J-3.
Transmission Remote Control Adjustment
•
Early
CJ-5A,
CJ-6A

First
disconnect the transmission shift rods from the remote control levers.
Check
for binding of
the remote control shaft on the steering column

and
make the necessary corrections to eliminate any binding condition.

If
the shift is not smooth and positive, first make

sure
the gears are in neutral position then remove
the shift rods at the transmission by removing
clevis pins, Fig. J-l No. 17, and slip a short piece
of snug fitting 34" [6,35 mm.] aligning rod, through
the gearshift levers and housing as shown in insert
drawing.

This
places the clutch and shift lever assemblies

in
the neutral position. Adjust the shift rod yokes
at the transmission end, so clevis pins can be in­ stalled freely without moving the shift levers on the
transmission after which remove alignment pin.
If
shifting from first to second is difficult or trans­
mission hangs in first gear, shorten the low and
reverse shift rod one
turn
at a time until the con­
dition is corrected. Usually three turns are re­

quired.

Should
the fault continue after completing the above adjustment, check further as outlined below.

First
remove the lubricating fitting. Use a narrow
feeler
gauge
which
will
enter the opening for the
lubricator
and check the clearance
between
the
faces of the shifting clutches.
This
clearance should
be .015" to .031", [W to W]
[0,397-0,794
mm.]. If
this clearance is greater the assembly must be removed for adjustment. The shift dog, which

engages
the clutch slots, should not have more than .009" [0,229 mm.] clearance in the slots. If the clear­
ance
between
the clutch
grooves
and cross pins is
too great,
these
parts must be replaced.

Check
clearance of shift dog which
engages
in slot
of clutches, and if found to be greater than .009" [0,229 mm.] clearance, replace the worn parts.
Assemble upper clutch lever assembly in housing
making
sure that the alignment

Turn
the upper lever as­
sembly in as far as it
will
go and then back off one

full
turn
until the
hole
in the clutch lever aligns

with
hole
in the housing.
Assemble the lower clutch lever assembly in hous­ ing until faces of clutches contact then back off
not more than one-half
turn
which should bring
the aligning
hole
in the lever in line with the
hole
in
the housing. If the one-half
turn
does
not bring
the alignment
hole
in proper position, it
will
be
necessary to grind off (square with axis not to exceed .015") [0,397 mm.] the face of the lower

clutch;
in other words, backing off not more than
one-half
turn
from face to face contact
gives
the

proper
clearance of .015" to .031"
[0,397-0,794
mm.]

between
the two clutches.
Assemble the unit to the steering
post

order
of dismantling and adjust remote control

rods.
After
assembly, if the shift dog catches on the
edge

of the slot in the clutch when moving the lever up

Separating Transmission
and

Transfer Case

a.
Remove the six screws and lockwashers attach­
ing the transfer case rear cover and remove the cover. Or, should the vehicle be equipped with a
power
take-off,
remove the power take-off shift
unit which replaces the cover.
b. Remove
cotter
pin, nut, and washer which
hold the transfer case main drive gear on the rear
end of the transmission mainshaft. If
possible
at
this point, remove the main drive gear. If not possible, see
steps
d and e
below.

c. Remove the transmission-to-transfer-case screws.

d.
Separate the transfer case from the transmission.
When separating the two units, use care that the
transmission mainshaft bearing, which bears in
both
housings, remains in the transmission housing.

To
separate the two units if the transfer case main
drive gear was not removed in
step
b
above,
follow

the procedure in
step
e
below.

e.
Install transmission mainshaft retaining plate,

tool
W-194, as shown in Fig. J-6 to prevent the mainshaft from pulling out of the transmission
case. Should this
tool
be unavailable,
loop
a
piece
of wire around the mainshaft directly back of the mainshaft
second-speed
gear. Install the transmis­
sion shift housing right and
left
front attaching
screws part way
into
the transmission case. Twist
the wire and attach each end to one of the screws.
Draw
the wire tightly. With the mainshaft securely

in
place, support the transfer case and, with a rawhide mallet or brass drift and hammer, tap 242
