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.

POWER STEERING PUMP

DISASSEMBLY

A clean working area should be

used when overhauling the power

steering pump. Foreign matter picked

up on working parts may cause dam-

age or failure of the unit. Clean con-

tainers should be used for parts.

1.
Drain the fluid from the pump.

Remove the pump cover-to-housing

cap screws (Fig. 1). Place the pump

on the bench, cover side down. Lift

the housing from the cover.

2.
Remove the large and the small

O-rings from the pump cover. Remove

the O-ring from the pressure plate

hub.

3.
Remove the pressure plate-

to-cover screws, and remove the plate.

Lift the cam ring off the dowel pins.

4.
Remove the rollers. Lift the

rotor off the shaft, and remove the

drive key from the shaft. Remove the

dowel pins from the cover.

5.
Remove the rotor shaft from the

cover. Do not remove the snap ring

from the shaft unless it, or the shaft,

is damaged.

6. Pry the rotor shaft seals out of

the cover and the housing.

7. Do not disturb the control valve

unless diagnosis indicated a control

valve problem or foreign matter in the

valve. To remove the valve, drive the

roll pin out of the housing. Remove

the plug and O-ring, control valve,

and the spring. If the plug or valve is

stuck, tap the end of the housing on a

piece of wood or tap it with a soft-

faced hammer. Remove the O-ring

from the plug.

ASSEMBLY

Apply automatic transmission fluid

to all parts as they are assembled. Al-

ways use new seals and O-rings.

1.
Install the control valve spring in

the housing. Install the valve with the

small sensing hole in the end of the

valve toward the spring. Install a new

O-ring on the plug. The plug O-ring is

1/8 inch smaller in diameter than the

bypass O-ring. Make sure the proper

O-ring is used. Install the plug and a

new roll pin (Fig. 1).

2.
The rotor shaft oil seals are in-

stalled in the cover and the housing

with Tool 3583-J, which consists of a

driver and an adapter. The procedure

is as follows:

a. Support the cover on wood

blocks (Fig. 2) to provide tool clear-

ance.
Use clean blocks that will not

nick or damage the inner face of the

cover.
b.
Start the seal (metal shell up-

ward) square!y into the bore with fin-

ger pressure. Place the adapter on the

driver with the square corner of the

FIG. 2—Preparation for Installing

Rotor Shaft Seals

adapter toward the seal (Fig. 2). Drive

the seal into the cover, as shown in

Fig. 3, until it bottoms.

Driving the seal beyond this point

can damage it. Install the seal in the

pump housing in the same manner.

3.
Install the rotor shaft in the

FIG. 3—Installing Rotor

Shaft Seals
cover as shown in Fig. 4 to prevent

damage to the seal.

4.
Install the dowel pins in the

cover. Place the rotor drive key in the

shaft. Install the rotor on the shaft

with the drive key groove aligned with

the key and the counterbored side of

the rotor toward the cover so that it

goes over the snap ring.

5.
Place the cam ring on the dowel

pins with the chamfered edge upward

(Fig. 5). Place the rollers in the rotor.

6. Place the pressure plate on the

dowel pins. Install and tighten the

screws to 20 in-lbs torque. Install the

O-ring on the pressure plate hub. In-

stall O-rings in the groove at the fluid

bypass hole and around the cam ring

(Fig. 6).

7.
Place the tool shown in Fig. 6 in

the rotor shaft to prevent damage to

the oil seal, then install the housing on

the cover. Install and torque the cap

screws to 15-20 ft-lbs.

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

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
marked teeth

on
the

IN-VEHICLE ADJUSTMENTS AND REPAIRS

REAR AXLE SHAFT, WHEEL

BEARING AND OIL SEAL

REPLACEMENT

The rear axle shafts, wheel bear-

ings,
and oil seal can be replaced

without removing the differential as-

sembly from the axle housing.

REMOVAL OF

AXLE SHAFT

Synthetic wheel bearing seals are

used in production only. Removal and

insertion of rear axle shafts must be

performed with caution. The entire

length of the shaft (including spline)

up to the seal journal must pass

through the seal without cutting of the

seal element during axle removal or

installation will result in early seal fai-

lure.
Leather seals only will be used as

service replacement for synthetic

wheel bearing seals.

1.
Remove the wheel cover, wheel

and tire from the brake drum.

2.
Remove the nuts that secure the

brake drum to the axle shaft flange,

then remove the drum from flange.

3.
Working through the hole pro-

vided in each axle shaft flange, re-

move the nuts that secure the wheel

bearing retainer plate. Then pull the

axle shaft assembly out of the axle

housing (Fig. 4). The brake backing

plate must not be dislodged. Install

one nut to hold the plate in place after

the axle shaft is removed.

REMOVAL OF REAR

WHEEL BEARING AND

SEAL

Synthetic seals must not be cleaned,

soaked or washed in cleaning solvents.

Removal of the wheel bearings from

the axle shaft makes them unfit for

further use.

1.
On all models except Ford, Mer-

cury or Meteor, if the rear wheel

bearing is to be replaced, loosen the

inner retainer ring by nicking it deeply

with a cold chisel in several places

(Fig. 5). It will then slide off easily.
E 1731-A

FIG. 5—Removing Rear Wheel

Bearing Retainer Ring

On Ford, Mercury and Meteor mo-

dels,
it is necessary to first drill a 1/4

inch hole not more than 5/16 inch

deep in the retainer ring surface bef-

ore using the cold chisel.

2.
Remove the bearing from the

axle shaft with the tool shown in Fig.

6 or Fig. 7.

3.
Whenever a rear axle shaft is re-

placed, the oil seal must be replaced.

Remove the seal with Tool 1175-AB

and a slide hammer (Fig. 8). If new

leather-type wheel bearing service

seals are to be installed, soak new oil

seals in SAE 10 oil for 1/2 hour

before installing.

INSTALLATION OF REAR

WHEEL BEARING AND

SEAL

1.
Inspect the machined surface of

the axle shaft and the axle housing for

rough spots or other irregularities

which would affect the sealing action

of the oil seal. Check the axle shaft

splines for burrs, wear or twist. Care-

fully remove any burrs or rough spots.

Replace worn or damaged parts.

2.
Lightly coat wheel bearing bores

with axle lubricant.

3.
Place the retainer plate on the

axle shaft, and press the new wheel

bearing on the shaft with the tool

shown in Fig. 6 or Fig. 9. Do not at-

tempt to press on both the bearing

and the inner retainer ring at the same

time.

4.
Using the bearing installation

tool (Tool 4621-A or 4234-4), press

the bearing inner retainer ring on the

shaft until the retainer seats firmly

against the bearing. On Ford, Mercu-

ry, or Meteor models, before assem-

bling the retainer onto the axle shaft,

the shaft journal and the inside di-
ameter of the retainer should be wiped

clean with a dry cloth. These parts

must not be degreased or lubricated.

5. Rear wheel oil seals with synthe-

tic sealing elements have been incor-

porated in production only. However,

leather seals only will be used as re-

placements for the synthetic sealing

elements. Install the new oil seal with

the tools shown in Figs. 10 and 12. Be

sure the new seal has been soaked in

SAE 10 oil for 1/2 hour before in-

stalling it. Wipe a small amount of oil

resistant sealer on the outer edge of

the seal before it is installed. Do not

put sealer on the sealing lip.

INSTALLATION OF

AXLE SHAFT

1.
Carefully slide the axle shaft into

the housing so that the rough forging

of the shaft will not damage the oil

seal. Start the axle splines into the

side gear, and push the shaft in until

the bearing bottoms in the housing.

2.
Install the bearing retainer plate

and the nuts that secure it. Torque the

nuts to specifications.

3.
Install the brake drum and the

drum attaching (Tinnerman) nuts.

4.
Install the wheel and tire on the

drum. Install the wheel cover.

DRIVE PINION OIL SEAL

REPLACEMENT

COLLAPSIBLE SPACER

Synthetic seals must not be cleaned,

soaked or washed in cleaning solvent.

The drive pinion oil seal can be re-

placed without removing the differen-

tial carrier assembly from the axle

housing.

1.
Raise the vehicle and install

safety stands. Remove both rear wheels

and brake drums.

2.
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. 11). Dis-

connect the drive shaft from the axle

U-joint flange. Be careful to avoid

dropping the loose universal joint

bearing cups. Hold the cups on the

spider with tape. Mark the cups so

that they will be in their original posi-

tion in relation to the flange when

they are assembled. Remove the drive

shaft from the transmission extension

housing. Install an oil seal replacer
