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.
Wash all parts in clean solvent

and dry them with clean cloths or

compressed air.

2.
Inspect the rotor shaft for wear,

scoring, nicks, or burrs. Replace the

shaft if it is damaged or if the inner

keyway is damaged.

3.
Inspect the rotor, rollers, cam

ring, pressure plate, cover, and bush-

ing in the pressure plate for wear or

scoring. If damaged, replacement of

the pump (less housing) is required.

4.
Make sure the inner faces of the

cover and the housing are free of

paint, nicks, or burrs. Check all fluid

passages for restrictions.

5.
Inspect the valving surfaces

(areas where the rotor and rollers con-

tact) for wear or scoring. Replace the

pressure plate or the cover if worn or

scored. Inspect the bushing in the

pressure plate for wear or scoring, and

replace the plate if necessary.

6. Inspect the control valve for

scores, nicks, or burred edges. Re-

place the valve if damaged. Do not dis-

assemble the valve. Check the valve

for free movement in the housing

bore.

7.
Inspect the tube seat in the hous-

ing. If damaged, remove it with an

E-Z-Out and install a new seat.

SHOCK ABSORBER CHECKS

All vehicles are equipped with hy-

draulic shock absorbers of the direct-

acting type and are nonadjustable and

nonrefillable. They cannot be repaired.
Before replacing a shock absorber,

check the action of the shock absor-

bers as follows:

ON VEHICLE TESTS

1.
Check the shock absorber to be

sure it is securely and properly in-

stalled. Check the shock absorber in-

sulators for damage and wear.

Replace any defective insulators and

tighten attachments to the specified

torque (on a shock absorber which in-

corporates integral insulators, replace

the shock absorbers).

2.
Inspect the shock absorber for

evidence of fluid leakage. A light film

of fluid is permissible. Be sure any

fluid observed is not from sources

other than the shock absorber.

Replace the shock absorber if leak-

age is severe.

3.
Disconnect the lower end of the

shock absorber. Extend and compress

the shock absorber as fast as possible,

using as much travel as possible.

Action should become smooth and

uniform throughout each stroke.

Higher resistance on extension than

on compression is a normal condition.

Faint swish noises are also normal.

Remove the shock absorber for a

bench test if action is erratic. If the
action is smooth, but the shock absor-

bers are suspected of being weak fol-

low step 4:

4.
Repeat step 3 on the mating

shock absorber installed on the oppo-

site side of the vehicle, and compare

results of both tests. If the action is

similar, it is unlikely that either shock

absorber is defective. Reconnect both

shock absorbers.

Replace the shock absorber having

the lower resistance. Ensure that the

part number of the replacement is the

same as that of the original shock ab-

sorber. The replacement shock absor-

ber resistance will appear to be higher

than either original due to initial fric-

tion of the rod seal.

BENCH TEST

With the shock absorber right side

up (as installed in vehicle), extend it

fully. Then turn the shock absorber

upside down and fully compress it.

Repeat this procedure at least three

times to ensure that any entrapped air

has been expelled. Now place the

shock absorber right side up in a vise,

and hand stroke the shock absorber as

described in On Vehicle Tests, step 3.

If action is not now smooth and uni-

form, install a new shock absorber.procarmanuals.com

IN-VEHICLE ADJUSTMENTS AND REPAIRS

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.

from the upper ball joint stud.

6. Place a box wrench over the

lower end of the ball joint remover

tool, and position the tool as in Fig. 7.

The tools should seat firmly against

the ends of both studs, and not

against the lower stud nut.

7.
Turn the wrench until both studs

are under tension, and then, with a

hammer, tap the spindle near the

upper stud to loosen the stud from the

spindle. Do not loosen the stud with

tool pressure alone. Remove the ball

joint.

8. Clean the end of the arm, and

remove all burrs from the hole edges.

Check for cracks in the metal at the

holes,
and replace the arm if it is

cracked.
