3.
With the steel tape still hooked

to the brake pedal depress the brake

pedal by pressing downward on the

brake pedal effort gauge. Apply a 50

pound load to the center of the pedal

by observing the pressure gauge, and

measure the distance from the brake

pedal to the fixed reference point on

the steering wheel rim parallel to the

centerline of the steering column.

4.
The difference between the brake

pedal free height and the depressed

pedal measurement under a 50 pound

load should be within the specified

maximum pedal travel service specifi-

cation B in Fig. I.

5.
If the pedal travel is more than

the specified maximum shown in Fig.

1,
dimension C, make several sharp

reverse stops (equivalent to 50 pounds

pedal pressure) with a forward stop

before each. Move the vehicle in rev-

erse and forward for a distance of ap-

proximately ten feet; then, apply the

brakes sharply and hold the brake

pedal down until the vehicle is com-

pletely stopped. This will actuate the

brake self-adjusters. If these stops do

not bring the brake pedal travel within

specification, make several additional

forward and reverse stops as outlined

above.

6. If the second series of stops do

not bring the brake pedal travel within

specification, remove the brake drums

and check the brake adjusters to make

sure they are functioning. Check the

brake linings for wear or damage. Re-

pair or replace all worn or damaged

parts and non-functioning adjusters.

Adjust the brake lining outside diame-

ter to the approximate inside diameter

of the brake drum with Rotunda Tool

HRE-8650 (Fig. 12, Part 2-2).

7.
If all the brake adjusters, brake

drums and linings are functional and

the brake travel is not within specifi-

cations, check the pedal linkage for

missing or worn bushings, or loose at-

tachments. Bleed the brakes and cen-

tralize the differential valve.

POWER BRAKE

FUNCTIONAL TEST

1.

CYLINDER PUSH
ROD

ADJUSTMENT

The push
rod is
provided with
an

adjustment screw
to
maintain
the cor-

rect relationship between
the
booster

control valve plunger
and the
master

cylinder.
If the
plunger
is too
long
it

will prevent
the
master cylinder piston

from completely releasing hydraulic

pressure
and can
cause
the
brakes
to

drag.
If the
plunger
is too
short
it
will

result
in
excess pedal travel
and an

undesirable clunk
in the
booster area.

The adjustment screw
is set to the

correct height
at the
time
of
original

assembly
of the
power unit. Under

normal service
the
adjustment screw

does
not
require
any
further attention

providing
the
original push
rod
assem-

bly remains
in the
original unit.

If
a
check
of the
push
rod
adjust-

ment
is
necessary,
the
push
rod
length

may
be
verified with
a
push
rod
length

gauge
and
measured with
the
engine

running
to
apply vacuum
to the

er (Fig.

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-

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-

ment. In the absence of such equip-

ment, portable equipment may be

used and the work may be performed

on a level floor. The floor area should

be level within 1/4 inch from front to

rear of the vehicle and within 1/8 inch

from side to side. Alignment height

spacers (Figs. 4, 8 and 9) are used to

check caster and camber. The spacers

should be omitted when checking toe-

in.

1.
Check the runout of each front

wheel and tire using a dial indicator

against the rim outer band. If the ru-

nout exceeds 1/8 inch, correction may

be made by rotating the wheel on the

drum. When the minimum runout has

been obtained, mark the point of

greatest runout so the wheels can be

positioned as shown in Fig. 10 when

checking the front end alignment.

Hold a piece of chalk against the

wheel rim or the tire sidewall while

spinning the wheels. The chalk will

mark the rim or tire at the point of

greatest runout.

2.
Drive the vehicle in a straight

line far enough to establish the

straight ahead position of the front

wheels, and then mark the steering

wheel hub and the steering column

collar (Fig. ll).Do not adjust the

steering wheel spoke position at this

time. If the front wheels are turned at

any time during the inspection, align

the marks to bring the wheels back to

the straight-ahead position.

3.
With the vehicle in position for

the front end alignment inspection and

adjustment, install the suspension

alignment spacers as follows to esta-

blish the curb height.

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-
