worm shaft to make sure that it ro-

tates freely.

7. Coat the threads of the steering

shaft bearing adjuster, the housing

cover bolts, and the sector adjusting

DESCRIPTION

The Ford Non-Integral Power

Steering System
(Fig. 1) is a
hydrauli-

cally controlled linkage-type steering

system which includes
an
integral

pump
and
fluid reservoir,
a
control

valve,
a
power cylinder,
the
connecting
fluid lines,
and the
steering linkage.

The hydraulic pump
and
belt, driven

from
the
engine crankshaft, draws

fluid from
the
reservoir
and
provides

fluid pressure
for the
system. Within

the pump itself
is a
pressure-relief
valve which governs
the
pressures

within
the
steering system according

to
the
varying conditions
of
operation.

After fluid
has
passed from
the
pump

to
the
control valve
and the
power
cyl-

inder,
it
returns
to the
reservoir.

6. After turning the front wheels

fully to the left, unthread the control

valve from the center link steering

arm-to-idler arm rod.

INSTALLATION

1.
Thread the valve onto the center

link until about four threads are still

visible on the link.

2.
Position the ball stud in the sec-

tor shaft arm.

3.
Measure the distance between

the center of the grease plug in the

sleeve and the center of the stud at the

inner end of the left spindle connect-

ing rod (Fig. 4). The distance should

be 5 5/8 inches for Montego, Falcon

and Fairlane vehicles. The distance

should be 4 7/8 inches for Mustang

and Cougar models. If the distance is

not correct, disconnect the ball stud

from the sector shaft arm and turn the

valve on the center link to increase or

decrease the distance.

4.
When the correct distance is ob-

tained and the ball stud is positioned

in the sector shaft arm, align the hole

in the steering arm-to-idler arm rod

with the slot near the end of the valve
sleeve. Install the roll pin in the rod

hole to lock the valve in position on

the rod.

5.
Torque the valve sleeve clamp

bolt to specification.

6. Install the nut on the ball stud,

and torque the nut to specification.

Install a new cotter pin.

7.
Connect the fluid lines to the

control valve, and tighten all fittings

securely. Do not over-tighten.

8. Fill the fluid reservoir with the

specified fluid to the cross hatched

area on the dip stick.

9. Start the engine and run it at

idle speed for about two minutes to

warm the fluid in the power steering

system.

10.
Turn the steering wheel all the

way to the left and right several times,

and check the system for fluid leaks.

11.
Increase the engine speed to

about 1000 rpm, and turn the steering

wheel all the way to the left and right

several times.

the position of the steering wheel

when the front wheels are in the

straight-ahead position.Do not make

any adjustments until toe-in is

checked.

15.
Keep the engine running, and

check toe-in. If either toe-in or steer-

ing wheel position is not correct make

all necessary adjustments (Part 3-1) at

the spindle connecting rod sleeves.

16.
Check the effort to turn the

wheels in both directions. The effort

should be about equal in both direc-

tions.

MAJOR REPAIR OPERATIONS

CONTROL VALVE

DISASSEMBLY

1.
Wipe all fluid and loose dirt

from the outside of the control valve.

2.
Remove the centering spring cap

from the valve housing (Fig. 6).

When holding the control valve for

disassembly, use a soft-jawed vise, and

clamp the valve only around the sleeve

flange to prevent damage to the hous-

ing, spool, or sleeve.

3.
Remove the nut from the end of

the valve spool bolt. Remove the

washers, spacer, centering spring,

adapter, and bushing from the bolt

and the valve housing.

4.
Remove the two bolts that hold

the valve housing and the sleeve to-

gether, and separate the housing from

the sleeve.

5.
Remove the plug from the valve

sleeve.

6. Push the valve spool out of the

centering spring end of the valve hous-

ing, and remove the seal from the

spool.

7.
Remove the spacer, bushing, and

seal from the sleeve end of the valve

housing.
8. Drive the stop pin out of the

travel regulator stop with a punch and

hammer (Fig. 7). Pull the head of the

valve spool bolt tightly against the

travel regulator stop before driving the

pin out of the stop.

9. Turn the travel regulator stop

counterclockwise in the valve sleeve to

remove the stop from the sleeve.

10.
Remove the valve spool bolt,

spacer, and rubber washer from the

travel regulator stop.

11.
Remove the rubber boot and

clamp from the valve sleeve.

12.
Slide the bumper, spring, and

ball stud seat out of the valve sleeve,

and remove the ball stud socket from

the sleeve.

13.
After removing the return port

hose seat, remove the return port re-

lief valve.

14.
After removing the spring plug

and O-ring, remove the reaction limit-

ing valve (Fig. 8).

Tube Seat Replacement

If a hose seat is worn or damaged it

should be replaced. It can be removed

with an Easy-Out tool, or by using a

bolt of appropriate size as a puller.
1.
Tap the existing hole in the hose

seat, using a starting tap of suitable

size.
Be sure to remove all metal chips

from the hose seat port after tapping.

2.
Place a nut and large flat washer

on a bolt of the same size as the

tapped hole. The washer must be large

enough to cover the hose seat port.

3.
Insert the bolt in the tapped

hole,
and using the nut as a puller, re-

move the hose seat.

4.
Place a new hose seat in the

port, and thread a bolt of suitable size

into the port. Tighten the bolt enough

to bottom the seat in the port.

ASSEMBLY

Before assembling the control valve,

coat all parts except the seals with

Automatic Transmission Fluid. Coat

the seals with lubricant COAZ-

19553-A.

1.
Install the reaction limiting

valve, the spring, and the plug.

2.
Install the return port relief valve

and the hose seat.

3.

REMOVAL

1.
Clamp the power cylinder in a

vise,
and remove the snap ring from

the end of the cylinder. Be careful not

to distort or crack the cylinder in the

vise.

2.
Pull the piston rod out all the

way to remove the scraper, bushing,

and seals. If the seals cannot be re-
moved in this manner, remove them

from the cylinder with a sharp pick.

Take care, when using a pick, not to

damage the shaft or seal seat.

INSTALLATION

When replacing the power cylinder

seals,
install all of the parts supplied

in the repair kit for the cylinder being

repaired.

1.
Coat the new seals with lubricant

COAZ-19553-A and place the parts

(Fig. 13) on the piston rod which has

been coated with the same grease.

2.
Push the rod in all the way, and

install the parts in the cylinder with a

deep socket slightly smaller than the

cylinder opening (Fig. 14).
