FABRICATING CLUTCH FIXTURE

Where

Rebuilding and Adjusting
Fixture

W-296 is not available, one can be fabricated if
desired.
It is necessary to make a mounting fixture,
nine spacers, and a
gauge
as shown in Fig. 1-20.
Proceed
as follows:

a.
For the mounting fixture, select a flat steel
plate 1" x 12" x 12" [2,54 x 3,05 x 3,05 cm.]. As shown in
Fig.
1-21,
drill
and tap six equally spaced

holes
3/8"-16
thread on the
ll-s/8"
[29,6 cm.]
dia­
meter bolt circle; and %"-18 thread on the 10-%" [27,1 cm.] diameter bolt circle.
Drill
and tap six

Jf6"-18
thread
holes
as indicated on the 9-%"
[24,10
cm.] diameter bolt circle. Hole spacing and
bolt circle tolerances should be held to plus or minus .002" [.050 mm.]. Countersink all
holes
to a depth of %" [8 mm.].
Drill
and tap the
holes
all
the way through the plate.

b.
From
steel bar stock any size from V2" [12
mm.] to 1V2" [2,86 cm.], make 3 spacers in each

move
the snap rings, pinch the ends
together
with

a
pair
of pliers. If the rings do not readily snap
out of the groove, tap the end of the bearing lightly
which
will
relieve pressure against the rings.
After
removing the snap rings, press on the end of
one bearing until the
opposite
bearing is pushed
from
the yoke arm.
Turn
the joint over and press
the first bearing back out of that arm by pressing
on the
exposed
end of the
journal
shaft. Use a
soft
ground drift with a flat face about [0,8 mm.]

smaller
in diameter than the
hole
in the yoke arm
and
drive it out, otherwise there is danger of damag­ing the bearing.

Repeat
this operation for the other two bearings,
then lift out
journal
assembly by sliding it to one
side.

Type Assembly

Wash
all parts in cleaning solvent and inspect the
parte
after cleaning. Replace any parts that indicate
extensive
wear.
It is advisable to install new gaskets
on the
journal
assembly regardless of the condition of the old gaskets. Make certain that the grease

channel
in each
journal
trunnion is open.

Pack
the bearing
cones
one-third
full
of lubricant
and
install the rollers.
Draw
the bearings into the end yoke arm and seat
them firmly against the bearing shoulders. Hold
the bearings in a vertical position to prevent the
needles
from dropping out until the joint is as­ sembled. If the joint binds when assembled, tap
the arms lightly to relieve any pressure on the bear­
ings at the end of the
journal.

L-5.
U-Bolt
Type Disassembly

Removal
of the attaching "U"-bolt releases one set
of bearing races. Slide the propeller shaft into the
yoke flange to remove them using care not to
lose
the rollers.
After
the removal of the one set of bearing races,
release the other set by removing the snap rings

in
the
sleeve
yoke by pinching the ends
together

with
a
pair
of pliers. Should the rings
fail
to snap
readily
from the groove, tap the end of the bearing
lightly,
which
will
relieve the pressure against them.

Press
on the end of one bearing, until the
opposite
bearing
is pushed out of the yoke arm.
Turn
the

universal
joint over and press the first bearing out
by pressing on the
exposed
end of the
journal
as­
sembly. Use a
soft
ground drift with a flat face about
\{i
[0,8 mm.] smaller in diameter than the
hole
in the yoke
arm
and drive out the bearing.
Lift

the
journal
out by sliding to one side.
Clean
all
parts
and check for wear.

L-6.
U-Bolt Type Assembly

Wash
all parts in cleaning solvent and inspect the
parts
after cleaning. Replace any parts that indicate
extensive
wear.
It is advisable to install new gaskets
on the
journal
assembly regardless of the condition
of the old gaskets. Make certain that the grease
channel
in each
journal
trunnion is open.

Pack
the bearing
cones
one-third
full
of lubricant
and
install the rollers.
Draw
the bearings into the end yoke arm and seat
them firmly against the bearing shoulders. Hold the
bearings in a vertical position to prevent the
needles
from dropping out until the joint is as­
sembled. If the joint binds when assembled, tap the arms lightly to relieve any pressure on the
bearings at the end of the
journal.
Tighten the
U-bolts equally. U-bolt torque wrench reading is 15 to 20 lb-ft. [2,07 a 2,76 kg-m.].

When
installing the assembly in the vehicle be sure
that the arrows on the propeller shaft and yoke

sleeve
are in alignment as shown in Fig. L-2, or
that the unmarked joints are aligned with the yokes in the same parallel plane.

Points for measuring frame alignment on vehicles

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.

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

The

nine positions for alignment on the draw bar and

may

up or down to change
the height of attachment.
Check
the attaching

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