The following procedure should be

followed when cleaning the relief valve

which is a part of the pump valve as-

sembly.

1.
Using a punch or rod of suitable

diameter, apply an even pressure in a

straight line to the tip of the relief

valve pin (Fig. 20). Depress the valve

two or three times to exhaust the oil

which is trapped in the assembly. Do

not hammer on the valve pin or hous-

ing.

2.
Submerge the assembly in a con-

tainer of clean solvent. Again applying

an even pressure to the tip of the relief

valve pin, (a sudden strong force could

push the pin through the relief valve

spool) move the valve in and out sev-

eral times, thereby thoroughly flushing

the assembly. Pressure created within

the valve bore when the valve is moved

inward should force the cleaning fluid

out through the sensing orifice. If this

does not occur, the sensing orifice

should be cleaned with a piece of wire.

The valve must move freely and even-

ly. If the pin is bent or damaged, or if

the valve binds, the pump valve must

be replaced.

INSPECTION

The following describes the compo-

nents of the power steering pump

which must be replaced regardless of

condition and how to determine when

other components should be replaced.

The outlet fitting hex nut may be

reused if the corners of the hex are

not rounded. The housing bolts may

be reused if the threads are not dam-

aged.

All gaskets and seals must be re-

placed with new components except

the rotor shaft seal which should be

reused unless it was leaking.

The reservoir assembly may be

reused if the reservoir seal and gasket

areas are not damaged (dents, scratch-

es,
etc.). The soldered joints of the re-

turn and fill tubes must not be loose

or bent. Be sure to check for a broken

baffle.

The housing or housing assembly

may be reused if there is no damage

(scratches, etc.) at reservoir gasket,

outlet fitting or cover seal areas.

If the outlet fitting is damaged, the

pump housing must be replaced. The

pressure plate springs may be reused

providing they are not bent, broken or

have not taken a set.

Do not reuse the retainer end plate

if it is burred or damaged. The upper

pressure plate may be reused if there

is no scoring on the wear surface. It is

acceptable to polish the phosphate

coating.
The rotor and cam assembly can be

reused if there is no wear other than

the removal of the phosphate coating

on the cam contour. Do not disas-

semble the rotor and cam assembly.

Push the rotor part way out the cam

insert taking care not to let the slip-

pers and springs fall out. Check the

cam ID for scoring and burning.

Check the rotor faces and OD for

scoring and chipping. Do not attempt

to repair or refinish the lower and

upper pressure plates, cam or rotor

assembly. When wear or burning is

encountered, replace, them with new

components.

Install a new rotor and cam assem-

bly if the slippers are worn. Replace

the springs if they are bent or broken.

Polishing the phosphate coating of the

slipper sealing surface is permissable.

The rotor shaft can be reused if the

front and rear thrust faces, the bush-

ing diameter and the shaft seal diame-

ter are not excessively worn or scored.

The housing plate and bushing as-

sembly may be reused if all of the

threaded holes are not damaged

beyond repair and the bushing diame-

ter is not scored or worn .0005 inch

over the maximum dimension of .6897

inch. Threaded holes can be repaired

by drilling out the damaged threads

and installing a helicoil insert. If the

bushing is scored or excessively worn,

a new plate and bushing assembly

must be installed.

With Tool T69P-3D608-A (using a

dial indicator) check the squareness of

the fixed dowel pin in the plate (Fig.

21).
The pin must be square with the

adjacent surface within .001 inch per

inch through a 180 degree arch.

A bent or broken dowel pin can be

replaced as follows:
1.
Hold the plate assembly in a

horizontal position and grip at least

an inch of the dowel pin in a vise. Tap

the plate with a plastic or a rubber

hammer to pull the pin from the

plate.

2.
Insert the support guide (Tool

T69P-3D608-B) over a dowel pin (Fig.

22) and press the pin into the plate to

a height of 1.68 inch (See Fig. 23).

The support guide tool will serve as a

stop guide. Be careful not to bend the

new dowel pin during installation.

3.
Again use Tool T69P-3D608-A

(with a dial indicaator) to check the

dowel pin squareness as outlined

above.

1.
Position the magnetized Tool

T68P-4602-A on a U-joint bearing

cap as shown in Fig. 15.

2.
With the tool suspended straight

down and the adjusting screw to the

left, adjust the dial on the tool until

the left-hand edge of the bubble is ex-

actly on the zero line.

3.
Position the vee magnet on the

drive shaft away from welds and bal-

ance weights (Fig. 15).

4.
Position the magnetized tool

(T68P-4602-A) on the vee magnet

with the adjusting screw to the left in

the same relative position as it was on

the bearing cap (Fig. 16).

5.
Read the position of the bubbles

left-hand edge on the scale to deter-

mine the drive shaft pinion angle. The

reading should be 3 1/2 degrees plus 1
degree on Ford, Mercury or Meteor

models, 7 1/4 degrees plus 3/4 degree

on Thunderbird or Continental Mark

III models.

Adjustment

If the pinion angle is not within

specifications, adjust the pinion angle

as follows:

The upper arm-to-axle housing bolt

and two eccentric washers form an ad-

justing cam mechanism (Fig. 17)

which will tilt the axle housing to the

required angle.

1.
Loosen the upper arm pivot bolt

nuts.

2.
If the angle is less than specifica-

tions,
rotate the adjusting cam for-

ward and recheck the angle. If the

angle is more than specification, ro-

tate the adjusting cam rearward and

recheck the angle.

3.
When the axle housing is adjust-

ed in such a way that the drive shaft

angle reading is within specification,

install new pivot bolt nuts and torque

to specification (Fig. 17).

4.
Lower the vehicle and road test

for proper axle operation.

REMOVAL AND INSTALLATION

HOISTING INSTRUCTIONS

Damage to steering linkage compo-

nents and front suspension struts may

occur if care is not exercised when po-

sitioning the hoist adapters of 2 post

hoists prior to lifting the vehicle.

If a 2 post hoist is used to lift the

vehicle, place the adapters under the

lower arms or the No. 1 crossmember.

Do not allow the adapters to contact

the steering linkage. If the adapters

are placed under the crossmember, a

piece of wood (2 x 4 x 16 inches)

should be placed on the hoist channel

between the adapters. This will pre-

vent the adapters from damaging the

front suspension struts.
