Reservoir replacement must be done

on a clean workbench. Cleanliness of

work area and tools is extremely im-

portant when repairing any hydraulic

unit. Thoroughly clean the exterior of

the pump with a suitable cleaning sol-

vent. Do not clean, wash or soak the

shaft oil seal in solvent. Plug the inlet

and outlet openings with plugs or

masking tape before cleaning the

pump exterior or removing the reser-

voir.

POWER STEERING PUMP

DISASSEMBLY

A clean working area should be

used when overhauling the power

steering pump. Foreign matter picked

up on working parts may cause dam-

age or failure of the unit. Clean con-

tainers should be used for parts.

1.
Drain the fluid from the pump.

Remove the pump cover-to-housing

cap screws (Fig. 1). Place the pump

on the bench, cover side down. Lift

the housing from the cover.

2.
Remove the large and the small

O-rings from the pump cover. Remove

the O-ring from the pressure plate

hub.

3.
Remove the pressure plate-

to-cover screws, and remove the plate.

Lift the cam ring off the dowel pins.

4.
Remove the rollers. Lift the

rotor off the shaft, and remove the

drive key from the shaft. Remove the

dowel pins from the cover.

5.
Remove the rotor shaft from the

cover. Do not remove the snap ring

from the shaft unless it, or the shaft,

is damaged.

6. Pry the rotor shaft seals out of

the cover and the housing.

7. Do not disturb the control valve

unless diagnosis indicated a control

valve problem or foreign matter in the

valve. To remove the valve, drive the

roll pin out of the housing. Remove

the plug and O-ring, control valve,

and the spring. If the plug or valve is

stuck, tap the end of the housing on a

piece of wood or tap it with a soft-

faced hammer. Remove the O-ring

from the plug.

ASSEMBLY

Apply automatic transmission fluid

to all parts as they are assembled. Al-

ways use new seals and O-rings.

1.
Install the control valve spring in

the housing. Install the valve with the

small sensing hole in the end of the

valve toward the spring. Install a new

O-ring on the plug. The plug O-ring is

1/8 inch smaller in diameter than the

bypass O-ring. Make sure the proper

O-ring is used. Install the plug and a

new roll pin (Fig. 1).

2.
The rotor shaft oil seals are in-

stalled in the cover and the housing

with Tool 3583-J, which consists of a

driver and an adapter. The procedure

is as follows:

a. Support the cover on wood

blocks (Fig. 2) to provide tool clear-

ance.
Use clean blocks that will not

nick or damage the inner face of the

cover.
b.
Start the seal (metal shell up-

ward) square!y into the bore with fin-

ger pressure. Place the adapter on the

driver with the square corner of the

FIG. 2—Preparation for Installing

Rotor Shaft Seals

adapter toward the seal (Fig. 2). Drive

the seal into the cover, as shown in

Fig. 3, until it bottoms.

Driving the seal beyond this point

can damage it. Install the seal in the

pump housing in the same manner.

3.
Install the rotor shaft in the

FIG. 3—Installing Rotor

Shaft Seals
cover as shown in Fig. 4 to prevent

damage to the seal.

4.
Install the dowel pins in the

cover. Place the rotor drive key in the

shaft. Install the rotor on the shaft

with the drive key groove aligned with

the key and the counterbored side of

the rotor toward the cover so that it

goes over the snap ring.

5.
Place the cam ring on the dowel

pins with the chamfered edge upward

(Fig. 5). Place the rollers in the rotor.

6. Place the pressure plate on the

dowel pins. Install and tighten the

screws to 20 in-lbs torque. Install the

O-ring on the pressure plate hub. In-

stall O-rings in the groove at the fluid

bypass hole and around the cam ring

(Fig. 6).

7.
Place the tool shown in Fig. 6 in

the rotor shaft to prevent damage to

the oil seal, then install the housing on

the cover. Install and torque the cap

screws to 15-20 ft-lbs.

REMOVAL AND INSTALLATION

REMOVAL

1.
To maintain drive line balance,

mark the relationship of the rear drive

shaft yoke and the drive pinion flange

of the axle (if the yellow alignment

marks are not visible) with the shaft

so that they may be installed in their

original positions.

2.
Disconnect the rear U-joint or

rear double cardan joint from the

companion flange. Wrap tape around

the loose bearing caps to prevent

them from falling off the spider. Pull

the drive shaft toward the rear of the

vehicle until the slip yoke clears the

transmission extension housing and

the seal. On Lincoln Continental

models, remove the three roller bear-

ing assemblies off the spline teeth in-

side the slip yoke (Fig. 3). Install the

appropriate tool in the extension

housing to prevent lubricant leakage.

INSTALLATION

1.
If either the rubber seal on the

output shaft or the seal in the end of

the transmission extension housing is
damaged in any manner, replace the

seal or seals as required. Also, if the

lugs on the axle pinion flange are

shaved or distorted so that the bear-

ings slide, replace the flange.

2.
On Lincoln Continental models,

install the bearing assemblies over the

spline teeth in the slip yoke. Lubricate

the yoke spline with B8A-19589-A lu-

bricant. This spline is sealed so that

the transmission fluid does not

"wash" away the spline lubricant

(Figs.
4 and 5). Remove the tool from
the extension housing. Install the yoke

on the transmission output shaft. Do

not allow the yoke assembly to bot-

tom on the output shaft with excessive

force.

Install the drive shaft so that the

index marks or the yellow mark (if

visible) on the yoke (light side) is in

line with the yellow mark on the com-

panion flange. This prevents vibration

which occurs when the balance of the

shaft and balance of the axle pinion

flange become additive instead of neu-

Three different three-speed trans-

missions are used. The C4 Automatic,

C6 Automatic and the FMX Auto-

matic. Part 7-1 covers testing, com-
mon adjustments and repairs, and

cleaning and inspection for the three

types of transmissions. Where there
are differences in procedures or speci-

fications, the type of transmission af-

fected will be designated.

l
AUTOMATIC TRANSMISSION TESTS

When diagnosing transmission

problems, refer to the Ford Car and

Truck Diagnosis Manual for the de-

tailed information on the items that

could be causing the problem.

The following preliminary checks

should be made before proceeding

with other diagnosis checks.

TRANSMISSION FLUID LEVEL

CHECK

1.
Make sure that the vehicle is

standing level. Then firmly apply the

parking brake.

2.
Run the engine at normal idle

speed. If the transmission fluid is cold

run the engine at fast idle speed

(about 1200 rpm) until the fluid reach-

es its normal operating temperature.

When the fluid is warm, slow the en-

gine down to normal idle speed.

3.
On a vehicle equipped with a

vacuum brake release, disconnect the

release line and plug the end of the
line;
otherwise the parking brake will

not hold the transmission in any drive

position.

4.
Shift the selector lever through

all positions, and place the lever at P.

Do not turn off the engine during the

fluid level checks.

5.
Clean all dirt from the transmis-

sion fluid dipstick cap before remov-

ing the dipstick from the filler tube.

6. Pull the dipstick out of the tube,

wipe it clean, and push it all the way

back into the tube. Be sure it is prop-

erly seated.

7.
Pull the dipstick out of the tube

again, and check the fluid level. The

fluid level should be above the ADD

mark. If necessary, add enough fluid

to the transmission through the filler

tube to bring the level between the

ADD and FULL marks on the dip-

stick. Do not overfill the transmission.

Install the dipstick, making sure it is

fully seated in the tube.
8. Connect the vacuum brake re-

lease line if so equipped, and test it

for proper operation.

FLUID AERATION CHECK

A fluid level that is too high will

cause the fluid to become aerated:

Aerated fluid will cause low control

pressure, and the aerated fluid may be

forced out the vent.

Check the transmission fluid level.

Low fluid level can affect the opera-

tion of the transmission, and may in-

dicate fluid leaks that could cause

transmission damage.

TRANSMISSION FLUID

LEAKAGE CHECKS

Check the speedometer cable con-

nection at the transmission. Replace

the rubber seal if necessary.

Leakage at the oil pan gasket often

can be stopped by tightening the at-

linkage may cause crossleakage and

subsequent transmission failure. Refer

to Linkage Adjustments in Part 7-2,

7-3 or 7-4 for detailed manual linkage

adjustment procedures.

CONTROL PRESSURE

CHECK

When the vacuum diaphragm unit is

operating properly and the downshift

linkage is adjusted properly, all the

transmission shifts (automatic and

kickdown) should occur within the

road speed limits specified in Part 7-5.

If the shifts do not occur within

limits or the transmission slips during

shift point, the following procedure is

suggested to determine engine, trans-

mission, linkage, vacuum diaphragm

unit or valve body problems.

1.
Using the automatic transmis-

sion tester (Fig. 4), attach the tachom-

eter to the engine and the vacuum

gauge to the transmission vacuum line

at the vacuum unit (Fig. 5).

. 4—Rotunda ARE-2905

Automatic Transmission Tester

T - FITTING
2.
Attach the pressure gauge to the

control pressure outlet at the trans-

mission (Figs. '., and 7).

3.
Firmly apply the parking brake

and start the engine.

On a vehicle equipped with a vacu-

um brake release, apply the service

brakes. The parking brake can not be

used because the brake automatically

releases when the transmission selec-

tor lever is moved to a drive position.

4.
Adjust the engine idle speed lo

the specified rpm. If the engine idle

speed cannot be brought within limits

by adjustment at the carburetor idle

adjustment screw, check the throttle

and downshift linkage for a binding

condition. If the linkage is satisfacto-

ry, check for vacuum leaks in the

transmission diaphragm unit (Fig. 8

or 9) and its connecting tubes and

hoses.
Check all other vacuum oper-

ated units (such as the power brake)

for vacuum leaks.
