Early
production transfer cases were equipped with
a
lVs" [2,86 cm.] diameter intermediate shaft

and
caged
needle
bearings. When installing the intermediate gear in early production transfer cases,

insert
the bearings in the gear, support the front

thrust
washer with Pilot Pin Tool W-192,
Fig.
K-10,
position the gears and
rear
thrust washer, and
insert
the shaft from the
rear
of the case.

Late
production transfer cases were equipped with
a
1
Vi"
[3,18 cm.] diameter intermediate shaft,

and
bearings consisting of individual rollers and
spacers.
A dummy shaft is required to install the
intermediate shaft. The dummy shaft should be slightly smaller in diameter than the intermediate
shaft and a little shorter than the width of the
intermediate gear. To install the intermediate gear,

first
load the bearing rollers and spacers in the gear using the dummy shaft.
Then
supporting the
front thrust washer with the fingers, position the gears and
rear
thrust washer and insert the shaft

from
the
rear
of the case, driving out the dummy
shaft.

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.

Frame Dimensions
Points for measuring frame alignment on vehicles
equipped with the F4

are shown in
Fig.

The correct measurements for each model

are
given in the table. Point A is at the front of the

frame.

A-B

between

measured
on a line parallel with the frame center-

line.
E and F show the shackle bolt centers in

tion (above or below) to the pivot bolt centers.

On

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

R-4, shows method of attachment and bracing of the Jeep draw bar. The braces and the reinforce­
ment installed in the frame

The

the height of attachment.
Check
the attaching

bolts
periodically to be sure they are tight at all
times.
