VALVE
GUIDE
1—Reamer
d.
Measure clearance of each valve stem in cor
responding valve guide. For intake valves, this
clearance
should be .0012" to .0032" [0,0305 a
0,0813
mm.]. For exhaust valves, this clearance should be .0015" to .0035"
[0,0381
a
0,0889
mm.]
at top of guide and .002" to .004"
[0,051
a 0,102 mm.] at bottom of guide. If this clearance is exces
sive, valve guides must be reamed with .004" [0,102 mm.] oversized reamer J-5830-1 and valves
replaced
by new valves with oversize stems.
Dl-63.
Cylinder
Head
and Valve
Repair
a.
If a valve stem has excessive clearance in its
guide, the guide must be reamed .004" [0,102 mm.]
oversize. Valves are available with oversize stems
to fit this valve guide diameter.
b.
Grind
valve faces or replace valves if necessary.
Valve
faces must be ground at an angle of 45 degrees. If a valve head must be ground to a
knife
edge
to obtain a true face, the valve should
be replaced.
c.
If necessary, grind valve seats at an angle of 45 degrees.
Grinding
a valve seat decreases valve
spring
pressure and increases the width of the seat.
The
nominal width of the valve seat is
[
1,59
mm.].
If a valve seat is wider than %" [1,98 mm.]
after grinding, it should be narrowed to specified
width
by the use of 20-degree and 70-degree stones.
Improper
operation of a hydraulic valve lifter may
result
if valve and seat are refinished to the extent
that the valve stem is raised more than .050" [1,27 mm.] above normal height. In this case, it
is necessary to grind off the end of the valve stetti or replace parts.
Note:
The normal height of the valve stem above
the valve spring seat surface of the head is
1.925"
[4,889 cm.].
d.
Lightly
lap the valves into seats with fine grind
ing compound. The refacing and reseating should
leave the refinished surfaces smooth and true so that a minimum of lapping
will
be required. Ex
cessive lapping
will
groove the valve face and pre
vent
good
valve seating.
e. Test valve seats for concentricity with guides,
and
for proper valve seating. Coat a small segment
of the valve face lightly with Prussian blue pig ment.. Insert the valve stem into its guide and
turn
the valve face against the seat. If the valve seat is concentric with the valve guide, a
mark
will
be made all around the seat. If the seat is not concentric with the guide, a
mark
will
be made
on only one side of the seat.
Clean
all pigment from both valve and seat. .Next,
coat a small segment of the valve seat lightly with
Prussian
blue pigment. Again insert the valve stem into its guide and rotate the valve face against the
seat. If the valve face is concentric with the valve
stem, and if the valve is seating all the way around,
pigment
will
coat the valve face with a uniform
band
around its entire perimeter. Both of
these
tests
are necessary to prove that proper valve seat
ing is obtained.
f. Inspect the valve springs visually for corrosion,
breaks,
and distortion.
With
a valve spring tester
check
each valve spring for proper tension. When
a
valve spring is compressed to a length of
1.640"
[4,166 cm.] (closed-valve condition), it should
have a tension of 64 lb. [29,03 kg.]. When a valve
spring
is compressed to a length of
1.260"
[3,200
cm.] (open-valve condition), it should have ten sion of 168 lb. [76,205 kg.]. Replace any valve
spring
which is visibly damaged or
does
not
meet
tension specifications.
Dl-64.
Valve Installation
Lubricate
valve stems with engine oil.
Install
valves, valve springs, spring retainers, and valve
retainers
on the cylinder head. Use the same equipment and reverse procedure used for removal.
Install
valve springs with closely wound coils to
ward
the cylinder head. Refer to Fig. Dl-29.

pulled
out to the first notch.
To
replace a parking lamp, remove two screws allowing the lens and colored reflector to be re
moved. Replace the lamp, which is recessed back
in
the housing.
If
the
complete
parking light assembly is to be
removed for service or replacement, disconnect the

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

Clutch Throwout
Release Bearing
The
clutch throwout or release mechanism consists
of a forked lever which pivots on a
ball
pivot threaded into the clutch housing. A throwout lever
return
spring is anchored to a clip under the
ball
pivot and holds the lever in contact with the
ball
pivot. The clutch throwout bearing, which is a
pre-lubricated
unit, is attached to the forked end of the throwout lever.
Never wash the clutch throwout release bearing in
gasoline or any solvent that
will
dissolve the
lubri
cant.
It is neither necessary nor possible to
lubri
cate this bearing at any time. Connect linkage
to the throwout release lever. Adjust free-play as

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.

Frame Dimensions
Points for measuring frame alignment on vehicles
equipped with the F4
engine
are shown in
Fig.
R-l
and
R-2.
The correct measurements for each model
are
given in the table. Point A is at the front of the
frame.
A-B

measured
on a line parallel with the frame center-
line.
E and F show the shackle bolt centers in

Straightening Frame
In
case the bending or twisting of the frame is not
excessive, it may be straightened.
This
should be
done
cold, as excessive heat applied to the frame
will
weaken it. For this reason it is recommended that badly damaged frame parts be replaced.
Note:
A technique known as "controlled heat" can
be utilized where a frame section is "squashed" and must be brought out without "tearing" or excessive
stretch
to the metal.
R-5.
Front
Axle
Alignment
After
it has been determined that the frame is prop
erly
aligned, the front axle alignment with the
frame
can be checked. The front axle is square
with
the frame if the distance
between
the front
and
rear
axle is the same on both sides. The dis
tance from the spring upper bushings to the front
axle on both sides should be equal.
Note:
Always inspect the springs for broken spring
center
bolts
when checking the frame and axle
alignment.
R-6. Draw Bar
Fig.
R-4, shows method of attachment and bracing of the Jeep draw bar. The braces and the reinforce
ment installed in the frame
rear
cross-member
channel
provide even distribution of the stresses
when moving a heavy load.
The
draw bar plate may be shifted to any one of
nine positions for alignment on the draw bar and
may
be used with the
offset
up or down to change
the height of attachment.
Check
the attaching
bolts
periodically to be sure they are tight at all
times.
