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.

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.

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.

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

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:

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.

CONTINENTAL MARK III

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-

the reading exceeds specifications

(Part 3-13), replace the upper ball

joint.

LOWER BALL JOINT

INSPECTION

Ford,
Mercury, Meteor,

Thunderbird, Lincoln Continental

and Continental Mark III

1.
Raise the vehicle and place

jacks under the lower arms as shown

in Fig. 12. This will unload the lower

ball joints.

2.
Adjust the wheel bearings as des-

cribed in Part 3-12.

3.
Attach a dial indicator to the

lower arm and position the indicator

so that the plunger rests against the

inner side of the wheel rim adjacent to

the lower ball joint.

4.
Grasp the tire at the top and

bottom and slowly move the tire in

and out (Fig. 19). Note the reading

(radial play) on the dial indicator. If

the reading exceeds specifications

(Part 3-13), replace the lower ball

joint.

Cougar, Fairlane, Falcon,

Montego, Mustang

1.
Raise the vehicle on a frame

contact hoist or by floor jacks placed

beneath the underbody until the wheel

falls to the full down position.

2.
Ask an assistant to grasp the

lower edge of the tire and move the

wheel in and out.

3.
As the wheel is being moved in

and out, observe the lower end of the

spindle and the lower arm.

4.
Any movement between the

lower end of the spindle and the lower

arm indicates ball joint wear and loss

of preload. If any such movement is

observed, replace the lower arm.

During the foregoing check, the

upper ball joint will be unloaded and

may move. Disregard all such move-

ment of the upper ball joint. Also, do

not mistake loose wheel bearings for a

worn ball joint.

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.

FLUSHING THE POWER

STEERING SYSTEM—ALL EXCEPT

LINCOLN CONTINENTAL AND

CONTINENTAL MARK III

Should it be necessary to replace an

inoperative power steering pump, the

need for flushing the steering system

is required when installing the new

pump.
1.
Remove the power steering pump

and remove the pulley as outlined in

Part 3-10.

2.
Install the pulley on a new

pump. Install the pump and connect

only the pressure hose to the pump

(Part 3-10).

3.
Place the fluid return line in a

suitable container and plug the reser-

voir return pipe.

4.
Fill the reservoir with lubricant

(C1AZ-19582-A).

5.
Disconnect the coil wire to pre-

vent the engine from starting and raise

the front wheels off the ground.

6. While approximately two quarts

of steering gear fluid are being poured

into the reservoir, turn the engine over

using the ignition key, at the same

time cycle the steering wheel from

stop to stop.

7.
As soon as all of the lubricant

has been poured in, turn off the igni-

tion key, and attach the coil wire.

8. Remove the plug from the reser-

voir return pipe, and attach the return

hose to the reservoir.

9. Check the reservoir fluid level; if

low, add fluid to the proper level. Do

not overfill.

10.
Lower the vehicle.

11.
Start the engine and cycle the

steering from stop to stop to expel

any trapped air from the system.
