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.

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.

Note:
The clutch release bearing is lubricated at
time of assembly and no attempt should be made
to lubricate it Refer to Fig. 1-23 when lubricating
the clutch throwout bearing collar. c. Reassembly

To
assemble the clutch to the flywheel, first put
a
small amount of light cup grease in the flywheel
pilot bushing, install the driven plate, with short
end of hub toward the flywheel, then place the pressure plate assembly in position.
With
a clutch
plate aligning arbor or a spare transmission main
shaft, align the driven plate splines leaving the
arbor
in position while tightening the pressure plate
screws evenly.
Next, assemble the flywheel housing to the
engine
and
reinstall the transmission and transfer case or
install
the
engine
in the vehicle, depending on the
procedure of removal. Make sure that the clutch
release bearing
carrier
return spring is hooked in place. For the remainder of the assembly reverse
the operations that were used in removing the
transmission and transfer case or the
engine
referring
to the instructions given in Section J for the transmission and Section D and Dl for the
engine.

d.
Adjust the clutch control cable so there is 3A" [19,05 mm.] free pedal travel. (Refer to Par. 1-3)

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

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,

ruin
the driven plate facings.
b. Make sure that splines in the driven plate hub
are
clean; apply a light coat of lubricant to splines
of hub and transmission drive gear shaft. Slide plate over gear shaft several times; remove plate
from shaft and wipe off
excess

deflate completely and then force the tire away

from
the rim throughout the entire circumference
until
the bead falls into the center of the wheel

rim.
If the vehicle is equipped with tires that use

an
inner tube, carefully remove the inner tube.
With
the inner tube removed, or on tubeless tires, a tire
removing tool should be used to remove the tire

from
the rim.

Installation
of the tire is made in the same manner
by first dropping one side of the tire into the center
of the rim and with a tire tool raise the bead over
the wheel
rim.
The inner tube can now be installed
on vehicles so equipped.
When
mounting the wheel, alternately tighten op­
posite stud nuts. After the nuts have been tightened

with
the wheel jacked up, lower the
jack
so wheel rests on the floor and retighten nuts. Torque nuts
to 60-75 lb.-ft. [8,3 a 10,4 kg-m.].

Note:
New "wide" tires have been given new sizes
by tire manufacturers. They use a letter as a key
unit
in the name size for the new wide treads.

The
single letter in front of the "70" indicates load rating, or the weight a tire can support safely
when inflated to 32 psi. The number 70 is used to show the
7-to-10
(70 percent) ratio of tire section height to width. The last two-digit number of the new sizes— 15 —
is
the rim diameter.
Radial

ply
tire sizes all contain the letter
"R"
to designate
radial
ply construction.
