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.

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.

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
