FIG. 18 —Removing Spool

from Valve Body

7.
Dip three new valve body O-

rings and teflon rings in C1AZ-

19582-A lubricant. Install the O-rings

on the valve body being careful not to

twist them. Slide the three teflon rings

into place over the O-rings being care-

ful not to stretch them any more than

necessary.

8. Lubricate a new dampener O-

ring and install it in the spool groove.

9. Assemble the stub shaft in the

valve body making sure that the

groove in the cap engages the pin in

the body. Tap the cap lightly with a

soft-faced hammer to seat it in the

valve body.

10.
Dip the valve spool in C1AZ-

19582-A. With the notch of the spool

toward the valve body, carefully slide

the spooi over the shaft and into the

body rotating it slightly to permit easy

entry. Make sure that the dampener

O-ring is distributed evenly to prevent

TEFLON RING
damage. Guide the spool to engage

the notch with the dowel in the body.

11.
Place the spool spring on the

stub shaft with the larger diameter

toward the spool. Work the small end

of the spring down over the shaft until

the small end is seated in the groove

of the stub shaft.

12.
If, during the assembly of the

valve, the stub shaft and end cap as-

sembly is allowed to slip out of en-

gagement with the valve body pin, the

spool will be permitted to enter the

valve body too far. The dampener O-

ring seal will expand into the valve

body fluid grooves preventing with-

drawal of the spool. Attempt to with-

draw the spool with a slight pull and

much rotary motion. If this does not

free the spool after several tries, make

sure that the spool is free to rotate;

place the valve body on a flat surface

with the notched end up, and tap the

spool with a wooden or plastic rod

until the O-ring seal is cut and the

spool can be removed. Replace the

dampener O-ring seal and proceed

with the assembly procedure as be-

fore.

RACK-PISTON

1.
Cut the teflon ring and the O-

ring from the piston.

2.
Place the assembly on a clean

lint-free cloth and remove the screws

that attach the ball return guide clamp

to the rack piston and remove the

clamp (Fig. 19).

3.
Lift the ball return guides from

the rack-piston.

4.
Remove Tool T65P-3D517-A

FIG. 20—Assembling Rack Piston

Apply Lubriplate liberally to one of

the ball return guides and install the

six remaining balls in the guide. Place

the other half of the guide in position

and insert them into holes in the

rack-piston. Be sure that the dark ball

in the guide is installed next to the

polished ball in the rack-piston. Install

the ball return guide clamp with

screws and lock washers. Tighten the

screws to 8-12 ft-lbs.

8. The worm groove is ground with

a high point in the center. V/hen the

rack-piston passes over this high point

there should be a preload of 1-4 in-

lbs.
Clamp the rack-piston in a vise

with soft jaws with the worm shaft

pointing up. To avoid distortion, do

not tighten the vise too tight.

9. Place the valve assembly on the

worm, engaging the worm drive pins.

Rotate the worm until it extends 1

1/4 inch from the rack-piston to the

thrust bearing face. This is the center

position.

10.
Place an in-lb torque wrench

with a 3/4-inch-deep wall 12-point

socket on the stub shaft, and rotate

the wrench through an arc of approxi-

mately 60 degrees in both directions

several times, then take a torque read-

ing. The highest average reading ob-

tained with the worm rotating should

be between 1-4 in-lbs.

12.
Note the ball size stamped on

the rack-piston and install the next

size larger balls to increase the pre-

load. If no number is stamped on the

rack-piston, the original ball code size

was No. 7.

A change of one ball size larger will

increase the preload approximately

one in-lb. Final preload on replace-

ment balls should be 2-3 in-lbs.

Remove the valve assembly from

the worm and the rack-piston from

the vise.

13.
Insert Tool T65P-3D517-A into

the plug end of the rack and piston to

contact the worm shaft (Fig. 22).

stub shaft as this could cause the stub

shaft and cap to pull out of the valve

body, allowing the spool seal to slip

into valve body fluid grooves. Install

the valve assembly by pushing on the

outer diameter of the valve body hous-

ing with the finger tips. Be sure that

the teflon rings are not binding inside

the housing. The valve assembly is

correctly seated when the fluid return

hole in the gear housing is fully vis-

ible.

DESCRIPTION

The roller-type hydraulic pump,

driven by the crankshaft, draws auto-

matic transmission fluid down the res-

ervoir and provides fluid pressure for

the system. Steering gear lubrication
is also provided by the same fluid

from the reservoir. Within the pump

itself is a flow-control and pressure-

relief valve which governs the pres-
sures within the steering system ac-

cording to the varying conditions of

operation. After fluid has passed from

the gear, it returns to the reservoir.

reached, tighten the pinion nut slowly,

until an additional preload of 8 to 14

in-lb over the original reading is

reached. (The preload should not ex-

ceed 8 to 14 in-lb over the original

reading, or bearing failure may result.

Under no circumstances should the

pinion nut be backed off to lessen pre-

load. If this is done, a new pinion

bearing spacer must be installed. In

addition, the U-joint flange must

never be hammered on, or power tools

used.

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-
