IN-VEH1CLE ADJUSTMENTS AND REPAIRS

VALVE SPOOL

CENTERING CHECK

1.
Install a 0-2000 psi pressure

gauge Tool T56L-33610-D in the pres-

sure line between the power steering

pump outlet port and the integral

steering gear inlet port.

2.
Make sure that the valve on the

gauge is in the fully open position.

3.
Check the fluid level in the reser-

voir and fill it to proper level with the

specified fluid.

4.
Start the engine and cycle the

steering wheel from stop-to-stop, to

bring the steering lubricant up to nor-

mal operating temperature. Stop the
engine and recheck the reservoir. Add

fluid if necessary.

5.
With the engine running at ap-

proximately 1000 rpm and the steer-

ing wheel centered, attach an inch-

pound torque wrench to the steering

wheel retaining nut. Apply sufficient

torque to the torque wrench in each

direction, either side of center, to get

a gauge reading of 250 psi.

6. The torque reading should be the

same in both directions when 250 psi

is reached. If the difference between

the readings exceeds 4 in-lbs, the

steering gear must be removed and the

valve centering shim removed from the

valve housing and a thicker or thinner
shim installed. Only one shim is to be

used. If the steering effort is heavy,

the shim thickness should be in-

creased. Shim thickness should be de-

creased if the steering effort is light to

the left.

The out of vehicle procedure for

valve centering check is the same as

for the in vehicle except the torque

and simultaneous pressure reading

must be made at the right and left

stops instead of either side of center.

DESCRIPTION

The roller-type hydraulic pump,

driven by the crankshaft, draws auto-

matic transmission fluid down the res-

ervoir and provides fluid pressure for

the system. Steering gear lubrication
is also provided by the same fluid

from the reservoir. Within the pump

itself is a flow-control and pressure-

relief valve which governs the pres-
sures within the steering system ac-

cording to the varying conditions of

operation. After fluid has passed from

the gear, it returns to the reservoir.

FIG. 3—Limited-Slip Differential Check

Using
a
torque wrench
of at
least

200 ft-lbs capacity, rotate
the
axle

shaft.
Be
sure that
the
transmission
is

in neutral,
one
rear wheel
is on the

floor,
and the
other rear wheel
is

raised
off the
floor.
The
torque
re-

quired
to
continuously rotate
the
shaft

should
be at
least
75
ft-lbs
or 40
ft-lbs

(Traction-Lok).
The
initial breakaway

torque
may
be
higher than
the
contin-

uous turning torque,
but
this
is nor-

mal.
The
axle shaft should turn with

^ven pressure throughout
the
check

without slipping
or
binding.

If
the
torque reading
is
less than

specified, check
the
differential
for

improper assembly.

A vehicle equipped with
a
limited-

slip differential will always have both

wheels driving.
If,
while
the
vehicle
is

being serviced, only
one
wheel
is

raised
off the
floor
and the
rear axle

is driven
by the
engine,
the
wheel
on

the floor will drive
the
vehicle
off the

stand
or
jack.

GEAR TOOTH CONTACT

PATTERN CHECK

When rolling
a
tooth pattern,
use

the special compound (tube) packed

with each service ring gear
and
pinion

set.

Paint
all
gear teeth
and
roll
a pat-

tern
as
described
in
Section
3.
After

diagnosing
the
tooth pattern
as ex-

plained here, make
the
appropriate

adjustments
as
outlined
in
Section
2.

In making
a
final gear tooth
con-

tact pattern check,
it is
necessary
to

recognize
the
fact that there
are
three

different types
of
gear sets, hunting,

non-hunting
and
partial non-hunting.

Each type
is
determined
by the num-
ber
of
teeth
in the
gears.
The non-

hunting
and
partial non-hunting types

can
be
identified
by the
paint timing

marks
on the
pinion
and
ring gear

teeth. (Part 4-2,
Fig. 51).
See
Part
4-5

for complete identification specifica-

tions.

ACCEPTABLE TOOTH

PATTERNS (ALL AXLES)

Figure
4
shows acceptable tooth

patterns
for all
axles.
Any
combina-

tion
of
drive
and
coast patterns will
be

acceptable.

In general, desirable tooth patterns

should have
the
following character-

istics:

1.
The
drive pattern should
be
fair-

ly well centered
on the
tooth.

2.
The
coast pattern should
be
fair-

ly well centered
on the
tooth.

3.
Some clearance between
the pat-

tern
and the top of the
tooth
is
desir-

able.

4.
There should
be no
hard lines

where
the
pressure
is
high.

The individual gear
set
need
not

conform exactly
to the
ideal pattern

to
be
acceptable.

Any combination
of
drive
and
coast

patterns shown
in Fig. 4 are
accep-

table.

Hunting Gear
Set

In
a
hunting-type gear
set, any one

pinion gear tooth comes into contact

with
all
ring gear teeth.
In
this type,

several revolutions
of
the
ring gear
are

required
to
make
all
possible gear

combinations.
Any combination
of
drive
and
coast

patterns shown
in
Fig.
4
will
be
acceep-

table.

Non-Hunting Gear
Set

In
a
non-hunting type gear
set, any

one pinion gear tooth comes into
con-

tact with only
a few
ring gear teeth.

In this type, only
one
revolution
of
the

ring gear
is
required
to
make
all
poss-

ible tooth contact combinations.
Any

combination
of
drive
and
coast
pat-

terns shown
in Fig. 4
will
be
accept-

able.

Partial Non-Hunting

Gear
Set

In
a
partial non-hunting type gear

set,
any one
pinion tooth comes into

contact with only part
of
the
ring gear

teeth,
but
more than
one
revolution
of

the ring gear
is
required
to
make
all

possible gear tooth combinations.
Any

combination
of
drive
and
coast
pat-

terns shown
in Fig. 4
will
be
accept-

able.

SHIM
AND
BACKLASH

CHANGES

Since each gear
set
rolls
a
charac-

teristic pattern,
the
patterns shown
in

Fig.
4 are
considered acceptable
and

should
be
used
as a
guide.
The
drive

pattern
is
rolled
on the
convex side
of

the tooth,
and the
coast pattern
is

rolled
on the
concave side.

The movement
of
tooth contact
pat-

terns with changes
in
shimming
can
be

summarized
as
follows:

Removable Carrier Type Axle

1.
Thicker shim with
the
backlash

set
to
specifications moves
the
pinion

further from
the
ring gear:

2.
Thinner shim with
the
backlash

set
to
specifications moves
the
pinion

closer
to the
ring gear:

If
the
patterns
are not
correct,

make
the
changes
as
indicated.
The

pinion need
not be
disassembled
to

change
a
shim.
All
that
is
required
is

to remove
the
pinion, bearing,
and re-

tainer assembly
and
install
a
different

shim. When reinstalling
the
pinion

and retainer assembly
of a
non-
hunt-

ing
or
partial non-hunting gear
set, be

sure that
the
marked tooth
on the pi-

nion indexes between
the

Tighten the pinion shaft nut,

rotating the pinion occasionally to in-

sure proper bearing seating, (Fig. 6)

and take frequent preload readings

until the preload is at the original rec-

orded reading established in step 3.

12.
After original preload has been

reached, tighten the pinion nut slowly,
until an additional preload of 6 to 12

in-lbs has been added.

The preload should not exceed the

amount shown above, or bearing fail-

ure may result.

Under no circumstances should the

pinion nut be backed off to lessen pre-

load. If this is done, a new pinion

bearing spacer must be installed. (In

addition, the U-joint flange must

never be hammered on, or pneumatic-

-tools used.)

13.
Remove the oil seal replacer

tool from the transmission extension
housing. Install the front end of the

drive shaft on the transmission output

shaft.

14.
Connect the rear end of the

drive shaft to the axle U-joint flange,

aligning the scribe marks made on the

drive shaft end yoke and the axle U-

joint flange (Fig. 14).

15.
Check the lubricant level. Make

sure the axle is in running position.

Add whatever amount of specified lu-

bricant is required to reach the lower

edge of the filler plug hole, located in

the carrier casting or housing cover.

REMOVAL AND INSTALLATION

REMOVAL

1.
Raise the vehicle and support it

with safety stands under the rear

frame member.

2.
Drain the lubricant from the

axle.

3.
Make scribe marks on the drive

shaft end yoke and the axle U-joint

flange to insure proper position of the

drive shaft at assembly (Fig. 14). Dis-

connect the drive shaft at the drive

pinion flange.

4.
Disconnect the lower end of the

shock absorbers.

5.
Remove the wheels, brake drums

and both axle shafts as outlined in the

foregoing Section 2.

6. Remove vent hose front vent

tube (Corbin clamp) and remove vent

tube from brake tube junction and

axle housing.

7.
Remove the hydraulic brake T-
fitting from the axle housing. Do not

open the hydraulic brake system lines.

Remove the hydraulic brake line from

its retaining clip on the axle housing.

8. Remove both axle shaft oil seals

with the tools shown in Fig. 8.

9. Remove both brake backing

plates from the axle housing and sus-

pend them above the housing with me-

chanic's wire. The hydraulic brake

10.
Support the rear axle housing

on a jack, and then remove the spring

clip nuts. Remove the spring clip

plates (Fig. 13)

11.
Lower the axle housing and re-

move it from under the vehicle.

12.
If the axle housing is being re-

placed, transfer all the differential and

pinion parts to the new housing. See

Section 4, Major Repair Operations.

INSTALLATION

1.
Raise the axle housing into posi-

tion so that the spring clip plates can

be installed. On a Montego or Fair-

lane,
position the spring upper insula-

tors and retainers between the axle

housing and springs and install the

lower insulators. Torque the spring

clip nuts to specification.

2.
Place the brake backing plates in

their normal position on the axle

housing. Use new gaskets on each side

of the brake backing plates.

3.
Install new axle shaft oil seals

with the tool shown in Fig. 8. Soak

the new seals in light weight engine oil

(SAE 10) for 1/2 hour before install-

ing them. Installation without use of

the proper tool will distort the seal

and cause leakage. Coat the outside

edges of the new oil seal with a non-

hardening type of sealer such as Per-

matex No. 2 or its equivalent.

4.
Install the axle shafts, brake

drums and wheels as outlined in Sec-

tion 2.

5.
Attach the hydraulic brake line

T fitting to the axle housing, and se-

cure the hydraulic brake line in its re-

tainer on the axle housing.

6. Install vent tube to brake tubeprocarmanuals.com
