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.

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.

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
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
marked teeth

on
the
ring gear
(Fig.
51,
Part
4-2).
