quire
a
shim between
the
pinion rear

bearing cone
and the
pinion gear
to

locate
the
pinion
for
correct tooth

contact with
the
ring gear.

When replacing
a
ring gear
and pin-

ion
it
should
be
noted that
the
original

factory installed shim
is of the
correct

thickness
to
adjust
for
individual vari-

ations
in
both
the
carrier casting
di-

mension
and in the
original gear
set

dimension; therefore,
to
select
the cor-

rect shim thickness
for the new
gear

set
to be
installed, follow these steps:

1.
Use a
micrometer
to
measure

the thickness
of the
original shim
re-

moved from
the
axle
and use the
same

thickness upon installation
of the re-

placement carrier assembly
or

If
further shim change
is nec-

essary,
it
will
be
indicated
in the
tooth

pattern check.

2.
If the
original shim
is
lost,
sub-

stitute
a
nominal shim
for the
original

and
use the
tooth pattern check
to de-

termine
if
further shim changes
are re-

quired. Nominal shim thicknesses
is

indicated
in
Part

A
new
ring gear
and

GEAR

If
the
ring gear runout check
(be-

fore disassembly) exceeded specifica-

tions,
the
condition
may be
caused
by

a warped gear,
a
defective case,
or ex-

cessively worn differential bearings.

To determine
the
cause
of
excessive

runout, proceed
as
follows:

1.
Press
the
original bearings
on

the one-piece differential case hubs

without
the
ring gear installed.

2.
Place
the
differential bearing

cups
on the
bearing cone
and
roller

and
set the
differential case
in the car-

rier.

case several revolutions in each direc-

tion while the bearings are loaded to

seat the bearings in their cups. This

step is important.

5. Again loosen the right nut to re-

lease the preload. Check to see that

the left nut contacts the bearing cup.

Using the dial indicator set-up shown

in Fig. 13, Part 4-1, adjust the preload

to 0.008 to 0.012 case spread for new

bearings or 0.005 to 0.008 for the

original bearings, if re-used.

6. Check the runout of the differen-

tial case flange with a dial indicator.

If the runout does not now exceed

specifications, install a new ring gear,

if the runout still exceeds specifica-

tions,
the ring gear is true and the

trouble is due to either a defective

casting or worn bearings.

7.
Remove the differential case

from the carrier and remove the side

bearings from the case.

8. Install new bearings on the case

hubs,
and again install the differential

assembly in the carrier without the

ring gear.

9. Check the case runout again with

the new bearings. If the runout is now

within limits, the old bearings were

excessively worn. Use the new bear-

ings for assembly. If the runout is still

excessive, the case is defective and

should be replaced.

ASSEMBLY OF AXLE

Refer to Part 4-1 of this Shop

Manual for Cleaning and Inspection

procedures before starting assembly

operations.

ASSEMBLY OF

DIFFERENTIAL CASE

1.
Place the ring gear on the differ-

ential case. Install the retaining bolts

and torque them to specification.

2.
If the differential bearings were

removed, press them on as shown in

Fig. 17.

3.
Insert the pinion gear shaft lock

bolt into the case (loosely).

INSTALLATION OF DRIVE

PINION AND

DIFFERENTIAL CASE

1.
Place the shim(s) and pinion rear

bearing cone on the pinion shaft.

Press the bearing and shim(s) firmly

against the pinion shaft shoulder (Fig.

18).

2.
Place a new pinion bearing pre-

load (collapsible) spacer on the pinion

shaft.

3.
Lubricate the pinion rear bearing

4.
Lubricate the pinion front bear-

ing with axle lubricant. Lubricate the

pinion front bearing cone and place it

in the carrier housing.

5.
Install a new oil seal in the car-

rier casting (Fig. 19).

6. Insert the drive pinion shaft (U-

joint) flange into the pinion seal and

hold it firmly against the pinion front

bearing cone. From the rear of the

carrier casting, insert the pinion shaft

into the flange.

7.
Apply a small amount of lubri-

cant to the washer side of the flange

nut and start the nut. Use a new nut.

Hold the flange with the tool shown in

Fig. 12 and tighten the pinion shaft

nut. As the pinion shaft nut is tight-

ened, the pinion shaft is pulled into

the front bearing cone and into the

flange.

As the pinion shaft is pulled into

the front bearing cone, pinion shaft

end play is reduced. While there is

still end play in the pinion shaft, the

flange and cone will be felt to bottom.

This indicates that the bearing cone

and flange have bottomed on the col-

lapsible spacer.

From this point, a much greater

torque must be applied to turn the

pinion shaft nut, since the spacer must

be collapsed. From this point, also,

the nut should be tightened very slow-

ly and the pinion bearing preload play

checked often, so that the pinion bear-

ing preload does not exceed the speci-

fied limits.

If the pinion shaft nut is tightened

to the point that pinion bearing pre-

load exceeds the limits, the pinion

shaft must be removed and a new col-

lapsible spacer installed. Do not de-

crease the preload by loosening the

compression between the pinion front

and rear bearing cones and the col-

lapsible spacer and may permit the

front bearing cone to turn on the pin-

ion shaft.

8. As soon as there is preload on

the bearings, turn the pinion shaft in

both directions several times to seat

the bearing rollers.

9. Adjust the bearing preload to

specification. Measure the preload

with the tool shown in Fig. 20.

10.
Apply a thin coating of lubri-

cant on the bearing bores so that the

differential bearing cups will move

easily.

11.
Place the cups on the bearings

and set the differential case assembly

in the carrier casting.

If the gear set is of the non-hunting

or partial non-hunting type, assemble

the differential case and ring gear as-

sembly in the carrier so that the

marked tooth on the pinion indexes

between the marked teeth on the ring

gear as shown in Fig. 49, Part 4-2.

In almost every case of improper

assembly (gears assembled out of

time),
the noise level and probability

of failure will be higher than they

would be with properly assembled

gears.

REMOVAL AND INSTALLATION

REMOVAL

1.
To maintain drive line balance,

mark the relationship of the rear drive

shaft yoke and the drive pinion flange

of the axle (if the yellow alignment

marks are not visible) with the shaft

so that they may be installed in their

original positions.

2.
Disconnect the rear U-joint or

rear double cardan joint from the

companion flange. Wrap tape around

the loose bearing caps to prevent

them from falling off the spider. Pull

the drive shaft toward the rear of the

vehicle until the slip yoke clears the

transmission extension housing and

the seal. On Lincoln Continental

models, remove the three roller bear-

ing assemblies off the spline teeth in-

side the slip yoke (Fig. 3). Install the

appropriate tool in the extension

housing to prevent lubricant leakage.

INSTALLATION

1.
If either the rubber seal on the

output shaft or the seal in the end of

the transmission extension housing is
damaged in any manner, replace the

seal or seals as required. Also, if the

lugs on the axle pinion flange are

shaved or distorted so that the bear-

ings slide, replace the flange.

2.
On Lincoln Continental models,

install the bearing assemblies over the

spline teeth in the slip yoke. Lubricate

the yoke spline with B8A-19589-A lu-

bricant. This spline is sealed so that

the transmission fluid does not

"wash" away the spline lubricant

(Figs.
4 and 5). Remove the tool from
the extension housing. Install the yoke

on the transmission output shaft. Do

not allow the yoke assembly to bot-

tom on the output shaft with excessive

force.

Install the drive shaft so that the

index marks or the yellow mark (if

visible) on the yoke (light side) is in

line with the yellow mark on the com-

panion flange. This prevents vibration

which occurs when the balance of the

shaft and balance of the axle pinion

flange become additive instead of neu-

CLEANING AND INSPECTION

RELEASE BEARING

Wipe all oil and dirt off the release

bearing. The bearing is prelubricated

and should not be cleaned with sol-

vent.

Inspect the bearing retainer for

loose spring clips and rivets.

Inspect the release bearing assembly

for burrs which may cause the assem-

bly to drag on the transmission bear-

ing retainer. Any such burrs should be

cleaned up with fine crocus cloth. If

burrs are found, inspect the transmis-

sion input shaft bearing retainer for

evidence of scoring. Any scoring

should be polished out with crocus

cloth. Coat the bearing retainer with a

thin film of lithium-base grease

(C3VY-19586-A). Prior to release

bearing installation, apply a light film

of lithium base grease (C3VY-

19586-A) on both sides of the release

lever fork where it contacts the release

bearing hub and retaining springs.

Apply a light film of lithium base

grease (C3VY-19586-A) plate to the

release bearing surface that contacts

the pressure plate fingers. Carefully

fill the grease groove inside the bear-

ing hub with lithium base grease (no

polyethylene). Clean all excess grease

from the bore of the bearing hub. Ex-

cess grease will be forced onto the

spline by the transmission input shaft

bearing retainer and will contaminate

the clutch disc. Also, care must be

exercised when applying lubricants to

the release bearing, release bearing

hub and the release lever fork to avoid

excessive grease from contaminating

the clutch disc.

Hold the bearing inner race and ro-

tate the outer race while applying

pressure to it. If the bearing rotation

is rough or noisy, replace the bearing.

Most release bearing failures are

caused by improper clutch pedal ad-

justments. If the clutch linkage does

not have enough free travel, the re-

lease bearing will constantly touch the

release fingers and will spin whenever

the engine is running.

When installing a release bearing on

vehicles equipped with separate hub

and bearing, use the tool shown in

Fig. 5.

Release bearing failure can be

caused by the release lever contact

points being out of plane. Check the

wear on the release bearing assembly

where the release lever contacts it.

If one side of the assembly shows

more wear than the other, the release
lever is bent out of plane, or is not

centering on the bracket on the fly-

wheel housing.

Misalignment between the engine

and transmission can cause release

bearing failure. Other symptoms of

misalignment are transmission jump-

ing out of gear, especially third gear,

drive line vibration; excessive wear in

the pilot bushing, excessive clutch disc

spin time resulting in gear clash, and

excessive transmission gear wear.

PRESSURE PLATE AND COVER

Inspect the surface of the pressure

plate for burn marks, scores, or rid-

ges.
Generally, pressure plate resur-

facing is not recommended. However

minor burn marks, scores, or ridges

may be removed. During the resurfac-

ing process, the flatness of the pres-

sure plate must be maintained. If the

pressure plate is badly heat-checked or

deeply scored, replace the pressure

plate and cover assembly. Clean pres-

sure plate and flywheel surfaces with a

suitable solvent, such as alcohol to be

sure the surfaces are free from any oil

film. Do not use cleaners with petrole-

um base, and do not immerse the

pressure plate in the solvent.

Place the plate on the floor, being

careful not to score or scratch the sur-

face.
Force each individual finger

down, then release quickly. If the fin-

ger does not return quickly, a binding

condition is indicated, and the pres-

sure plate should be replaced.

The pressure plate should be lubri-

cated with a lithium-base grease be-

tween the driving lugs and the edges

of the pressure plate openings, as

shown in Fig. 6. Depress the pressure

plate fingers fully, apply the lubricant,

and then move the fingers up and

down until the lubricant is worked in.

Do not apply excessive lubricant.

CLUTCH DISC

Inspect the clutch disc facings for

oil or grease. Eliminate the source of

any oil or grease before replacing the

disc. An excessive amount of grease in

the pilot bushing or release bearing

hub will find its way to the disc fac-

ings.
Too much lubricant in the trans-

mission or a plugged transmission

vent will force the transmission lubri-

cant out the input shaft and onto the

disc facings. Also, rear main bearing

oil seal leaks or oil leaks from the fly-

wheel mounting bolts can contaminate

the clutch disc.
Inspect the clutch disc for worn or

loose facings. Check the disc for worn

or loose facings. Check the disc for

distortion and for loose rivets at the

hub.
Check for broken springs.

Springs loose enough to rattle will not

cause noise when the car is operating.

Replace the disc assembly if any of

these defects are present. Be especially

careful when installing a new disc to

avoid dropping it or contaminating it

with oil or grease.

PILOT BUSHING

Check the fit of the clutch pilot

bushing in the bore of the crankshaft.

The bushing is pressed into the

crankshaft and should not be loose.

Inspect the inner surface of the bush-

ing for wear or a bell-mouthed condi-

tion. If the bushing is worn or dam-

aged, replace the bushing with a new

service bearing. Refer to the applica-

ble engine for the replacement proce-

dure.
