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.

CENTERING CHECK

1.
Install a 0-2000 psi pressure

gauge Tool T56L-33610-D in the pres-

sure line between the power steering

pump outlet port and the integral

steering gear inlet port.

2.
Make sure that the valve on the

gauge is in the fully open position.

3.
Check the fluid level in the reser-

voir and fill it to proper level with the

specified fluid.

4.
Start the engine and cycle the

steering wheel from stop-to-stop, to

bring the steering lubricant up to nor-

mal operating temperature. Stop the
engine and recheck the reservoir. Add

fluid if necessary.

5.
With the engine running at ap-

proximately 1000 rpm and the steer-

ing wheel centered, attach an inch-

pound torque wrench to the steering

wheel retaining nut. Apply sufficient

torque to the torque wrench in each

direction, either side of center, to get

a gauge reading of 250 psi.

6. The torque reading should be the

same in both directions when 250 psi

is reached. If the difference between

the readings exceeds 4 in-lbs, the

steering gear must be removed and the

valve centering shim removed from the

valve housing and a thicker or thinner
shim installed. Only one shim is to be

used. If the steering effort is heavy,

the shim thickness should be in-

creased. Shim thickness should be de-

creased if the steering effort is light to

the left.

The out of vehicle procedure for

valve centering check is the same as

for the in vehicle except the torque

and simultaneous pressure reading

must be made at the right and left

stops instead of either side of center.

factory adjustments will change. These

changes in adjustment do not neces-

sarily affect the satisfactory operation

of the steering gear assembly, and

therefore ordinarily do not require

readjustment unless there is excessive

lash or other malfunctioning.

ADJUSTMENT IN

VEHICLE

The only adjustment which can be

performed is the total over center

position load, to eliminate excessive

lash between the sector and rack

teeth.

1.
Disconnect the pitman arm from

the sector shaft.

2.
Disconnect the fluid return line

at the reservoir, at the same time cap

the reservoir return line pipe.

4.
Remove the ornamental cover

from the steering wheel hub and turn

the steering wheel to 45 degrees from

the left stop.

5.
Using an in-lb torque wrench on

the steering wheel nut, determine the

torque required to rotate the shaft

slowly through an approximately 1/8

turn from the 45 degree position.

6. Turn the steering gear back to

center, then determine the torque re-

quired to rotate the shaft back and

forth across the center position. Loos-

en the adjuster nut, and turn the ad-

juster screw in (Fig. 2) until the read-

ing is 8-9 in-lb greater than the torque

45 degrees from the stop.

Tighten the lock nut while holding

the screw in place.

7.
Recheck the readings and replace

pitman arm and steering wheel hub

cover.

8. Connect the fluid return line to

the reservoir and fill the reservoir with

specified lubricant to the proper level.

REMOVAL AND INSTALLATION

on the steering shaft. Turn the steer-

ing wheel so that the spokes are in the

horizontal position.

2.
Center the steering gear input

shaft.

3.
Slide the steering gear input

shaft into the flex coupling and into
place on the frame side rail. Install

the three attaching bolts and torque

them to specification.

4.
Make sure that the wheels are in

the straight ahead position, then in-

stall the Pitman arm on the sector

shaft. Install and tighten the sector

shaft and install and tighten the at-

taching bolts to specification.

5.
Move the flex coupling into

place on the input and steering co-

lumn shaft and install and tighten the

attaching bolts to specification.

6. Connect and tighten the fluid

pressure and the return line to the

steering gear.

7.
Fill the power steering pump and

cycle the steering gear. Check for

leaks and again check the fluid level.

Add fluid as required.

MAJOR REPAIR OPERATIONS

In most cases, complete disassembly

of the power steering gear will not be

necessary. It is suggested that only

those assemblies that are faulty be dis-

assembled. Disassembly and reassem-

bly of the unit and the subassemblies

must be made on a clean workbench.

As in repairing any hydraulically op-

erated unit, cleanliness is of utmost

importance. Therefore, the bench,
tools,
and parts must be kept clean at

all times. Thoroughly clean the exter-

ior of the unit with a suitable solvent

and when necessary, drain as much of

the hydraulic oil 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.
VALVE CENTERING

SHIM REPLACEMENT

1.
Hold the steering gear over a

drain pan in an inverted position and

cycle the input shaft several times to

drain the remaining fluid from the

gear.

2.
