4.
Connect a tachometer, start the

engine and operate it at idle speed

until the reservoir fluid temperature

reaches 165 to 175. This temperature

must be maintained throughout the

test. Valve B may be partially closed

to create a back pressure up to 350

psi to hasten the temperature rise. The

reservoir fluid must be at the proper

level.

5.
With the engine operating at rec-

ommended idle rpm and fluid temper-

ature noted in Step 4, close the manu-

al valve B. The minimum acceptable

pressure reading is 620 psi.

6. If the pressure gauge reading is

below the minimum specification, the

pump is at fault and should be re-

paired with necessary parts.

7.
If the reading is at or above the

minimum specification, the pump flow

is normal. Open manual valve B and

proceed to the Pump Fluid Pressure

Test.

PUMP FLUID

PRESSURE TEST

1.
Keep the lines and tools con-

nected as in the Pump Flow Test.

2.
With manual valves A and B

opened fully, operate the engine at

recommended idle speed (Fig. 2).

Close manual valve A, then manual

valve B. Do not keep both valves

closed for more than 5 seconds as this

would abnormally increase the fluid

temperature and cause undue pump

and/or gear wear.

3.
With the valves fully closed, the

pressure gauge should read 1000 psi

minimum for Ford, Mercury, Meteor

or Thunderbird and 750 psi minimum

for Cougar, Fairlane, Falcon, Monte-

go or Mustang.

4.
If the pressure gauge reading is

below the minimum specification, the

pump is at fault and should be re-

paired with necessary parts.

5.
If the pressure gauge reading is

at or above the minimum specifica-

tions,
the pump is normal and the

power steering gear or power assist

control valve is at fault.

FLUID PRESSURE TEST-

LINCOLN CONTINENTAL AND

CONTINENTAL MARK III

The pressure testing gauge set, tool

T56L-33610-D, requires modification

to make it adaptable for installation

in the power steering hydraulic sys-

tem. The parts required and the modi-

fication procedure are as follows:

Thread).

d. Flared Tube Female Coupling

(3/8 inch OD Tube x 1/4 inch Pipe

Thread).

The connectors and the coupling are

standard-type fittings and can be pur-

chased locally.

e. To modify tool T56L-33610-D,

remove the hose from the hand shut-

off valve block. Install the 3/8 inch x

1/4 inch inverted flare connector in

the valve block, and assemble the

pressure line to the connector (Fig. 3).

Assemble the 3/8 x 1/4 inch coupling

and the 5/16-inch connector to the

free end of the hose leading to the.

pressure gauge.

1.
To check the pump pressure, dis-

connect the front and rear sections of

the pressure line over the number 6

cylinder. Connect the modified pres-

sure-testing gauge assembly, tool

T56L-3361O-D, between the two sec-

tions.

2.
Make sure the hand-valve at the

gauge is fully opened. Start the engine

and cycle the steering gear from stop

to stop to warm up the fluid. Check

the fluid level in the reservoir and add

fluid, if necessary.

3.
Turn the steering wheel to the

full right and full left turn positions

and observe the gauge readings.

Hold the wheels in this position

only long enough to obtain an accu-

rate reading. Do not exceed 5 seconds.

The gauge should read between

1120 and 1250 psi. If the pressure is
less than 1120 psi, close the valve at

the gauge and note the pump pressure.

If it is low with the valve closed, it in-

dicates that the pump is not operating

properly. If the pressure goes up with

the valve closed, it indicates that the

low pressure in the system must be

due to internal leakage in the power

unit, providing all connections are

tight.

4.
Remove the pressure testing

gauge set, and connect the pressure

line at the steering gear. Fill and bleed

the system.

FRONT WHEEL ALIGNMENT

CHECKS

Do not attempt to check and adjust

front wheel alignment without first

making a preliminary inspection of

the front-end parts. Refer to Section

3.

Check all the factors of front wheel

alignment except the turning angle

before making any adjustments. The

turning angle should be checked only

after caster, camber, and toe-in have

been adjusted to specifications.

The front wheel alignment specifica-

tions given in Part 3-13, are correct

only when the vehicle is at curb load.

Before checking or adjusting the

alignment factors, the suspension

alignment spacers must be installed to

obtain the curb Height.

EQUIPMENT INSTALLATION

Equipment used for front wheel

alignment inspection must be accu-

rate.
Whenever possible, front wheel

alignment checks should be performed

on stationary wheel aligning equip-

CLEANING
AND
INSPECTION

FRONT
END
GENERAL

INSPECTION

Do not check and adjust front

wheel alignment without first making

the following inspection for front-end

damage, or wear.

1.
Check for specified air pressures

in all four tires.

2.
Raise the front of the vehicle off

the floor. Shake each front wheel

grasping the upper and lower surfaces

of the tire. Check the front suspension

ball joints and mountings for loose-

ness,
wear, and damage. Check the

brake backing plate mountings. Tor-

que all loose nuts and bolts to specifi-

cation. Replace all worn parts as out-

lined in Part 3-2.

3.
Check the steering gear mount-

ings and all steering linkage connec-

tions for looseness. Torque all mount-

ings to specifications. If any of the

linkage is worn or bent, replace the

parts as outlined in Part 3-5.

4.
Check the front wheel bearings.

If any in-and-out free play is noticed,

adjust the bearings to specifications.

Replace worn or damaged bearings as

outlined in Part 3-12.

5.
Spin each front wheel with a

wheel spinner, and check and balance

each wheel as required.

6. Check the action of the shock

absorbers. If the shock absorbers are

not in good condition, the vehicle may

not settle in a normal, level position,

and front wheel alignment may be af-

fected.

WHEEL INSPECTION

Wheel hub nuts should be inspected

and tightened to specification at pre-

delivery. Loose wheel hub nuts may

cause shimmy and vibration. Elongat-

ed stud holes in the wheels may also

result from loose hub nuts.

Keep the wheels and hubs clean.

Stones wedged between the wheel and

drum and lumps of mud or grease can

unbalance a wheel and tire.
Check for damage that would affect

the runout of the wheels. Wobble or

shimmy caused by a damaged wheel

will eventually damage the wheel bear-

ings.
Inspect the wheel rims for dents

that could permit air to leak from the

tires.

POWER STEERING GEAR

CLEANING

Disassembly and assembly of the

steering gear and. the sub-assemblies

must be made on a clean workbench.

As in repairing any hydraulically op-

erated unit, cleanliness is of utmost
importance. The bench, tools, and

parts must be kept clean at all times.

Thoroughly clean the exterior of the

unit with a suitable solvent and, when

necessary drain as much of the hy-

draulic fluid as possible. Handle all

parts very carefully to avoid nicks,

burrs,
scratches and dirt, which could

make the parts unfit for use.

Do not clean, wash or soak seals in

cleaning solvent.

INSPECTION

1.
Check the sector shaft contact

surface in the cover for wear. If worn,

replace the cover.

2.
Inspect the input shaft bearing

for cracked races and the balls for

looseness, wear, pitting, end play or

other damage. Check the fit of the

bearing on the input shaft. Replace

the bearing, if required.

3.
Inspect the valve housing for

wear, scoring or burrs.

4.
Inspect the tube seats in the

pressure and return ports in the valve

body for nicks, etc. If necessary, re-

move and replace.

5.
Check the sector shaft contact

surface in the housing for wear. If

worn, replace the bushing or the hous-

ing.

6. Check all fluid passages for ob-

struction or leakage.

7.
Inspect the steering gear housing

for cracks, stripped threads, and mat-

ing surfaces for burrs. Inspect the pis-

ton bore of the housing for scoring or

wear. If necessary, replace the hous-

ing.

8. Check the input shaft bearing

after installation to be sure that it ro-

tates freely.

9. If the valve spool is not free in

the valve housing, check for burrs at

the outward edges of the working

lands in the housing and remove with

a hard stone. Check the valve spool

for burrs and if burrs are found, stone

the valve in a radial direction only.

Check for freedom of the valve again.

10.
Check the piston rack teeth and

sector shaft teeth for nicks and burrs.

DESCRIPTION

The Ford integral power steering

unit
(Fig. 1) is a
torsion-bar type
of

hydraulic assisted system. This system

furnishes power
to
reduce
the
amount

of turning effort required
at the
steer-

ing wheel.
It
also reduces road shock

and vibrations.

The torsion
bar
power steering unit

includes
a
worm
and
one-piece rack

piston, which
is
meshed
to the
gear

teeth
on the
steering sector shaft.
The

unit also includes
a
hydraulic valve,

valve actuator, input shaft
and
torsion

bar assembly which
are
mounted
on

the
end of the
worm shaft
and
operat-

ed
by the
twisting action
of the tor-

sion
bar.

The torsion-bar type
of
power steer-

ing gear
is
designed with
the one
piece
rack-piston, worm
and
sector shaft
in

one housing
and the
valve spool
in an

attaching housing
(Fig. 1).
This makes

possible internal fluid passages
bet-

ween
the
valve
and
cylinder, thus
eli-

minating
all
external lines
and
hoses,

except
the
pressure
and
return hoses

between
the
pump
and
gear assembly.

The power cylinder
is an
integral

part
of the
gear housing.
The
piston
is

double acting,
in
that fluid pressure

may
be
applied
to
either side
of the

piston.

A selective metal shim located
in

the valve housing
of the
gear
is for the

purpose
of
tailoring steering gear
ef-

forts.
If
efforts
are not
within specifi-

cations they
can be
changed
by in-
creasing
or
decreasing shim thickness

as follows:

Efforts heavy
to the
left—Increase

shim thickness.

Efforts light
to the
left—Decrease

shim thickness.

A change
of one
shim size will
in-

crease
or
decrease steering efforts
ap-

proximately
1 1/2
in-lbs.

Shims
are
available
in the
following

thicknesses
and are
notched
on the

outside diameter
for
identification:

0.0057-0.0063 inch—0 notch

0.0077-0.0083 inch—1 notch

0.0097-0.0103 inch—2 notches

0.0117-0.0123 inch—3 notches

0.0137-0.0143 inch—4 notches

Do
not use
more than
one
shim.
