1 TESTING
POWER STEERING-
PRELIMINARY TESTS
The following preliminary checks
should always be made before per-
forming any operations.
AIR BLEEDING
Air in the power steering system
(shown by bubbles in the fluid) should
be bled. After making sure that the
reservoir is filled to specification (the
fluid must be at normal operating
temperature when the check is made),
turn the steering wheel through its full
travel three or four times. Do not hold
the wheels against their stops. Re-
check the fluid level.
CHECK FLUID LEVEL
Run the engine until the fluid is at
normal operating temperature. Then
turn the steering wheel all the way to
the left and right several times, and
shut off the engine.
Check the fluid level in the power
steering reservoir. The level must show
on the cross hatching between the bot-
tom of the dipstick and the full mark
(Fig. 1). If the level is low, add
enough automatic transmission fluid
C1AZ-19582-A to raise the level to
the F mark on the dipstick. Do not
overfill the reservoir.
CHECK PUMP BELT
If the pump belt is broken, glazed,
or worn, replace it with a new belt.
Use only the specified type of belt.
Refer to Part 3-13 for belt adjustment
procedure.
CHECK FOR FLUID
LEAKS
With the engine idling, turn the
steering wheel from stop to stop sever-
al times. Check all possible leakage
points. Tighten all loose fittings, and
replace any damaged lines or defective
seats.
CHECK TURNING EFFORT
With the front wheels properly al-
igned and tire pressures correct, check
the effort required to turn the steering
wheel.
G 1508- A

1.
With the vehicle on dry concrete,
set the parking brakes.
2.
With the engine warmed up and
running at idle speed, turn the steering
wheel to the left and right several
times to warm the fluid.
3.
Attach a pull scale to the rim of
the steering wheel. Measure the pull
required to turn the wheel one com-
plete revolution in each direction. The
effort required to rotate the steering
wheel should not exceed specifications
given in Part 3-13.

valve is causing the trouble. Steps out-
lined below should be followed to de-
termine the cause of the trouble.
PUMP FLOW TEST
1.
Depending on the equipment
present on the vehicle (air condition-
ing, power brakes, standard transmis-
sion),
one of the following options
may be used to connect the pump
pressure and return hoses to the test
tool (T56L-3361O-D and T68L-
33610-A):
a. Disconnect the pressure and re-
turn lines at the power steering pump
(Fig. 2). Obtain a power steering re-
turn hose from stock and connect the
end with the fitting to the output fit-
ting of the tool using the
5/8-18
SAE
female, 1/4 N.P. thread male fitting
provided. The end of the stock hose
(without the fitting) should be con-
nected to the return tube of the pump.
Connect the pressure hose from the
tool to the outlet fitting of the pump.
b.
Disconnect the pressure line at
the pump and connect the pressure
line from the test tool to the outlet fit-
ting of the pump. Disconnect the re-
turn line at the gear and connect it to
the output fitting of the tool, using the
5/8-18
SAE female, 1/4 N.P. thread
male fitting provided.
2.
After installing the lines by the
most advantageous method, proceed
as follows:
3.
Open the manual valves A and B
fully (Fig. 2).

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.

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:

c. Inverted Flare Connector (5/16

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-

type of equipment is used, follow the
installation and inspection instructions
provided by the equipment manufactu-
rer.
CASTER
Check the caster angle at each front
wheel.
The caster is the forward or rear-
ward tilt of the top of the wheel
spindle (Fig. 12). If the spindle tilts to
the rear, caster is positive. If the
spindle tilts to the front, caster is neg-
ative. The correct caster angle, or tilt,
is specified in Part 3-13.
On Mustang, Cougar, Fairlane,
Falcon and Montego vehicles, the
maximum caster difference for check-
ing purposes must not exceed one de-
gree.
If setting is necessary, then the
maximum difference must not exceed
1/2 degree. On all other vehicles, the
maximum caster difference must never
exceed 1/2 degree.
CAMBER
Check the camber angle at each
front wheel.
Camber is the amount the front
wheels are tilted at the top (Fig. 12).
If a wheel tilts outward, camber is
positive. If a wheel tilts inward, cam-
ber is negative. The correct camber
angle, or outward (positive) tilt is
specified in Part 3-13.
On Mustang, Cougar, Fairlane,
Falcon and Montego vehicles, the
maximum camber difference for
checking purposes must not exceed
one degree. If setting is necessary,
then the maximum difference must
not exceed 1/2 degree. On all other
vehicles, the maximum camber differ-
ence must never exceed 1/2 degree.
TOE-IN
Alignment height spacers should not
be used to check and adjust toe-in.
Toe-in should only be checked and ad-
justed after the caster and camber
have been adjusted to specifications.
Check the toe-in with the front
wheels in the straight-ahead position.
Run the engine so that the power
steering control valve will be in the
center (neutral) position (if so
equipped). Measure the distance be-
tween the extreme front and also be-
tween the extreme rear of both front
wheels. The difference between these
two distances is the toe-in or toe-out.
Correct toe-in, or inward pointing
of both front wheels at the front is
specified in Part 3-13.
FRONT WHEEL
TURNING ANGLE
When the inside wheel is turned 20
degrees, the turning angle of the out-
side wheel should be as specified in
Part 3-13. The turning angle cannot
be adjusted directly, because it is a re-
sult of the combination of caster,
camber, and toe-in adjustments and
should, therefore, be measured only
after these adjustments have been
made. If the turning angle does not
measure to specifications, check the
spindle or other suspension parts for a
bent condition.

Caster and camber is adjusted by
loosening the bolts that attach the
upper suspension arm inner shaft to
the frame side rail, and moving the
inner shaft in or out in the elongated
bolt holes with the tool shown in Fig.
13.
The tool should be installed with
the tool pins in the frame holes and
the hooks over the upper arm inner
shaft. Then, tighten the tool hook nuts
snug before loosening the upper arm
inner shaft attaching bolts.
Caster
To adjust the caster angle, tighten
the tool front hook nut or loosen the
rear hook nut (Fig. 14) as required to
increase caster to the desired angle.
To decrease caster, tighten the tool
rear hook nut or loosen the front
hook nut as required (Fig. 14). The
caster angle can be checked without
tightening the inner shaft attaching
bolts.
Check the camber adjustment to
be sure it did not change during the
caster adjustment and adjust if neces-
