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.

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.

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.

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.

ential Bearing Preload Adjustments.

If the tooth pattern indicates a change

in shim thickness, follow the proce-

dure under Pinion Location.

REMOVABLE CARRIER

TYPE AXLE

The shim location for the removable

carrier type axle is between the pinion

retainer and the carrier (Fig. 13).

When adjusting this type carrier re-

ducing shim thickness will move the

pinion toward the ring gear; increas-

ing shim thickness will move the pi-

nion away from the ring gear (Fig.

13).

8. If the runout is still excessive, re-

place the companion flange and check

the runout. If necessary, rotate the

new flange on the pinion shaft until an

acceptable runout is obtained.

If excessive runout is still evident

after replacement of the companion

flange, it will be necessary to replace

the ring and pinion gear, and repeat

the above checks until runout is within

specifications.

PINION AND RING GEAR

TOOTH CONTACT

ADJUSTMENT

Two separate adjustments affect pin-

ion and ring gear tooth contact.

They are pinion location and backlash

(Figs.
12 and 13).

Individual differences in matching

the differential housing and the gear

set require the use of shims to locate

the pinion for correct contact with the

ring gear.

When adjusting either type axle,

shim thickness should be increased or

reduced only as indicated by the tooth

pattern check described in the fore-

going Section 1.

If the tooth pattern check indicates

a change in backlash only, follow the

Tooth Contact Adjustment—

Removable Carrier Axles
The shim location for the integral

carrier type axle, is between the pi-

nion gear and the pinion rear bearing

cone (Fig. 12). When adjusting this

type axle, increasing shim thickness

moves the pinion toward the ring

gear; reducing shim thickness moves

the pinion away from the ring gear

(Fig. 12).

BACKLASH AND DIFFERENTIAL

BEARING PRELOAD

ADJUSTMENTS (ALL AXLES)

On a Light-Duty (WER) Axle, it is

necessary to remove the rear axle

shafts prior to performing the adjust-

ment procedures. Refer to Rear Axle

Shaft Wheel Bearing and Oil Seal Re-

placement—Light-Duty (WER), Axle,

Part 4-4, Section 2.

To secure a more uniform control

of differential side bearing preload in

service repairs, a dial indicator set-up

such as shown in Fig. 12 is used.

In both types of axle (Fig. 11 and

12),
the ring gear is moved away from

or toward the pinion as described in

the following procedure.

1.
Remove the adjusting nut locks,

loosen the differential bearing cap

bolts,
then torque the bolts to 15 ft-lbs

on integral carrier type axle; 20 ft-lbs

on removable carrier type axles before

making adjustments.

2.
The left adjusting nut is on the

ring gear side of the carrier. The right

nut is on the pinion side. Loosen the

right nut until it is away from the cup.

Tighten the left nut until the ring gear

is just forced into the pinion with

0.000 backlash then rotate the pinion

several revolutions to be sure no bind-

ing is evident. (Recheck the right nutprocarmanuals.com
