Hazard
Warning Lights

All
current production vehicles
are
equipped with

a
four-way flasher warning system.
The
control switch
is
located
on the
instrument panel left
of

the steering column.
With
the
switch pulled
out,
the
two
front and
two
rear
turn
signal lights flash
on and
off
simultaneously,
as do
both
turn
signal

indicator
lights
on the
instrument clusters.
H-140.
Marker
Lights and Reflector Assembly

The
marker
lights
and
reflector assemblies
on

current
production vehicles
are
mounted
on the

side
of
the front fender and
on the
side
of
the
rear
quarter
panel.
The
spare wheel also mounts
a

marker
light. Some earlier production vehicles have
reflex reflectors mounted on the side of the hood and
on
the
side
of
the
rear
quarter panel. determine
if
dash wiper switch or wiring
is at
fault,
disconnect wiring harness from wiper motor
and

try
operating wiper independently
of
dash switch.
If
still
inoperative
see
procedure under
Par.
H-145.
b. Wiper
will
not
shut
off
— Determine
if
wiper
has both
low
and high speeds, slow speed only,
or

high speed only.
It is
important that
the
wiper
operates
at low
speed during parking cycle.
Dis­
connect wiring harness from wiper motor
and try

operating wiper independently
of
dash switch.
If

wiper
shuts
off
correctly with
crank
arm
in
park
position and wiper has both speeds, check
the
lead

between
terminal
and
dash switch ground
and

check
for
defective dash switch.
If
wiper shuts
off

correctly,
but has
high speed only, check lead
be­

tween wiper terminal and dash switch
for an
open

circuit
and check
for
defective dash switch.
If
still

inoperative,
see
Par. H-145.
c. Wiper
has
only fast speed.
Check
for
defective dash switch
or
open lead
between
terminal
and

dash switch.

H-141.
Windshield Wiper System

Early
production vehicles equipped with
the
Dauntless V-6
engine
have
two
single speed wind­
shield wiper motors mounted above
the
windshield inside
the
vehicle. The wiper motors
are
operated

and
controlled
by a
switch located
on the
instru­
ment panel.

Current
production vehicles with stationary wind­
shield have
a
two-speed
electric windshield wiper motor mounted below
the
windshield outside
the

vehicle on the driver's side. The wiper motor switch is located
on the
instrument panel
to the
left
of

the steering column.

H-142.
Two-Speed Wiper Motor

The
two-speed
electric wiper motor
is
operated and
controlled
by a
turn
type, three poled, dash switch,
containing
a 6
amp. circuit breaker.
Current
flow
is directed from
the
battery through
the
ignition
switch
to the
wiper dash switch assembly
to the

two-speed
wiper motor, which passes current from the designated motor brush (high,
low or
park)
to

the armature circuit
to
ground.

H-143.
Troubleshooting Procedure
Troubleshooting procedures
are
divided into
two

categories: wiper troubleshooting
in
vehicle; wiper
troubleshooting
on
bench.
Fig. H-65 and H-66

illustrates connecting leads
of the
two-speed
wiper for either bench operation
or to run
wiper inde­
pendently
of
dash switch and vehicle wiring when
installed
in the
vehicle.
H-144. Wiper Troubleshooting
in
Vehicle

Typical
wiper troubles and remedies are
as
follows
:

a.
Wiper
is
inoperative
—
Check
wiper switch
cir­

cuit
breaker; wiring harness connection
at
wiper
motor
and
wiper switch; wiper motor
feed
wire

from
ignition starter switch
to
wiper switch;
and
check wiper
on
switch
to be
securely mounted.

With
ignition switch
on,
check
for 12
volts
at
har­

ness
terminal that connects
to
wiper terminal.

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
Shaft
Lever
and Tube Type

Refer
to Fig. 1-1.

Note:
Two different
Clutch
Control
Lever
and

Tube
Assemblies have
been
installed on 'Jeep*

Universal
vehicles equipped with a V-6
engine
and

T14A
transmission.
Should difficulty in shifting the transmission be
noted, check the length of the clutch release pedal
