DESCRIPTION

The Rotary Valve Safety power

steering gear operates entirely on dis-

placing fluid to provide hydraulic fluid

pressure assists only when turning. As

the entire gear assembly is always full

of fluid, all internal components of the

gear are immersed in fluid making

periodic lubrication unnecessary. In

addition, this fluid acts as a cushion
to absorb road shocks that may be

transmitted to the driver. All fluid

passages are internal except the pres-

sure and return hoses between the

gear and pump.

The rotary valve provides a smooth

transmission through the driving range

of steering wheel effort. A torsion bar

transmits the road feel to the driver.
Response of the steering gear to effort

applied to the steering wheel has been

greatly increased.

The rack-piston nut is one piece and

is geared to the sector shaft. Lash be-

tween the sector shaft and rack-piston

nut is maintained by an adjusting

screw which is retained in the end o\'

the shaft uear (Eiiz.l).

IN-VEHICLE ADJUSTMENTS AND REPAIRS

During the breaking in period of

the vehicle, it is probable that some

of the factory adjustments will change.

These changes in adjustment do not

necessarily affect the satisfactory op-

eration of the steering gear assembly

and ordinarily do not require re-ad-

justment unless there is excessive lash

or other malfunctioning. The only ad-

justment that should be performed in

the vehicle is the total over center

position load (mesh load) to eliminate

excessive lash between the sector shaft

and rack teeth.

MESH LOAD ADJUSTMENT

1.
Disconnect the Pitman arm from
the sector shaft and remove the steer-

ing wheel hub.

2.
Disconnect the fluid return line

at the reservoir; at the same time cap

the reservoir return line pipe.

3.
Place the end of the return line

in a clean container and cycle the

steering wheel in both directions as

required, to discharge the fluid from

the gear.

4.
Turn the gear 1/2 turn off cen-

ter (either direction). Using a 24 in-

lb torque wrench on the steering wheel

nut, determine the torque required to

rotate the shaft slowly through a 20

degree arc.

5.
Turn the sear back to center and
repeating the method of reading tor-

que as in Step 4, above, loosen the

adjuster lock nut, turn the screw in-

ward with a 7/32-inch Allen wrench

until the reading is equal to 6 in-lbs

in excess of Step 4 above, and retigh-

ten the lock nut while holding the

screw in place.

6. Recheck the readings and re-

place the Pitman arm and the steering

wheel hub.

7.
Connect the fluid return line to

the reservoir and fill the reservoir

with C1AZ-I9582-A Fluid to the

proper level.

9. Install the cam and rotor assem-

bly onto the pump housing plate with

the fixed dowel passing through the

first hole to the left of the cam notch

when the arrow on the cam OD is

pointing toward the lower pressure

plate (Fig. 13). If the cam and rotor

assembly will not seat, turn the rotor

shaft slightly until the spline teeth

mesh, allowing the cam and rotor to

drop down into position.

properly installed the heights of the

two dowels must be equal. Squirt the

rotor, springs, slippers and cam insert

with C1AZ-19582-A lubricant.

11.
Place the upper pressure plate

with the face having the tapered notch

down against the cam insert. The

fixed dowel should pass through the

l
FLYWHEEL HOUSING ALIGNMENT

Alignment of the flywheel housing

bore and rear face with the engine

should be checked as a possible cause

of any of the following troubles- ex-

cessive transmission gear wear, ..ans-

mission jumping out of gear, especial-

ly third gear, drive line vibration, ex-

cessive pilot bushing wear, noisy re-

lease bearing, or excessive clutch spin

time.

INSPECTION

1. With the clutch release bearing

removed, install the indicator pilot

tool shown in Fig. 1.

2.
Clean the faces of the flywheel

housing bolt bosses, and remove all

burrs, nicks, and paint from the

mounting face of the housing.

3.
Install the dial indicator on the

pilot and adjust the holder so the but-

ton will contact a circumference just

inside of the transmission mounting

holes.

4.
Push the flywheel forward to re-

move crankshaft end play. Set the dial

indicator face to read zero.

5.
Remove the spark plugs to alle-

viate compression.

6. Pull the engine crankshaft

through one revolution. The crank-

shaft must be held in the forward po-

sition while rotating it.

7. Note the indicator reading and

mark the maximum point of runout

on the face of the housing (Fig. 1).
8. Position the dial indicator to

check bore alignment (Fig. 1). The

bore must be clean and free of burrs,

nicks and paint.

9. Pull the crankshaft through one

revolution. Note the indicator reading

and mark the maximum point of run-

out on the face of the housing as

shown in Fig. 1.

10.
Remove the dial indicator from

the crankshaft and the housing.

11.
Select the Dia-L-lgner pilot

(Fig. 2) which will fit snugly in the

bore of the flywheel housing.

12.
Press the pilot into place on the

locator on the back of the dial.
13.
Position the Dia-L-lgner on the

face of the housing (Fig. 3) with the

pilot in the bore.

14.
Rotate the face runout arrow to

the positive face runout mark on the

housing.

15.
Without moving the face runout

arrow, rotate arrow A until it is at the

negative bore reading.

16.
Slide arrow A to register the

amount of bore runout on the .010-

CLEANING AND INSPECTION

RELEASE BEARING

Wipe all oil and dirt off the release

bearing. The bearing is prelubricated

and should not be cleaned with sol-

vent.

Inspect the bearing retainer for

loose spring clips and rivets.

Inspect the release bearing assembly

for burrs which may cause the assem-

bly to drag on the transmission bear-

ing retainer. Any such burrs should be

cleaned up with fine crocus cloth. If

burrs are found, inspect the transmis-

sion input shaft bearing retainer for

evidence of scoring. Any scoring

should be polished out with crocus

cloth. Coat the bearing retainer with a

thin film of lithium-base grease

(C3VY-19586-A). Prior to release

bearing installation, apply a light film

of lithium base grease (C3VY-

19586-A) on both sides of the release

lever fork where it contacts the release

bearing hub and retaining springs.

Apply a light film of lithium base

grease (C3VY-19586-A) plate to the

release bearing surface that contacts

the pressure plate fingers. Carefully

fill the grease groove inside the bear-

ing hub with lithium base grease (no

polyethylene). Clean all excess grease

from the bore of the bearing hub. Ex-

cess grease will be forced onto the

spline by the transmission input shaft

bearing retainer and will contaminate

the clutch disc. Also, care must be

exercised when applying lubricants to

the release bearing, release bearing

hub and the release lever fork to avoid

excessive grease from contaminating

the clutch disc.

Hold the bearing inner race and ro-

tate the outer race while applying

pressure to it. If the bearing rotation

is rough or noisy, replace the bearing.

Most release bearing failures are

caused by improper clutch pedal ad-

justments. If the clutch linkage does

not have enough free travel, the re-

lease bearing will constantly touch the

release fingers and will spin whenever

the engine is running.

When installing a release bearing on

vehicles equipped with separate hub

and bearing, use the tool shown in

Fig. 5.

Release bearing failure can be

caused by the release lever contact

points being out of plane. Check the

wear on the release bearing assembly

where the release lever contacts it.

If one side of the assembly shows

more wear than the other, the release
lever is bent out of plane, or is not

centering on the bracket on the fly-

wheel housing.

Misalignment between the engine

and transmission can cause release

bearing failure. Other symptoms of

misalignment are transmission jump-

ing out of gear, especially third gear,

drive line vibration; excessive wear in

the pilot bushing, excessive clutch disc

spin time resulting in gear clash, and

excessive transmission gear wear.

PRESSURE PLATE AND COVER

Inspect the surface of the pressure

plate for burn marks, scores, or rid-

ges.
Generally, pressure plate resur-

facing is not recommended. However

minor burn marks, scores, or ridges

may be removed. During the resurfac-

ing process, the flatness of the pres-

sure plate must be maintained. If the

pressure plate is badly heat-checked or

deeply scored, replace the pressure

plate and cover assembly. Clean pres-

sure plate and flywheel surfaces with a

suitable solvent, such as alcohol to be

sure the surfaces are free from any oil

film. Do not use cleaners with petrole-

um base, and do not immerse the

pressure plate in the solvent.

Place the plate on the floor, being

careful not to score or scratch the sur-

face.
Force each individual finger

down, then release quickly. If the fin-

ger does not return quickly, a binding

condition is indicated, and the pres-

sure plate should be replaced.

The pressure plate should be lubri-

cated with a lithium-base grease be-

tween the driving lugs and the edges

of the pressure plate openings, as

shown in Fig. 6. Depress the pressure

plate fingers fully, apply the lubricant,

and then move the fingers up and

down until the lubricant is worked in.

Do not apply excessive lubricant.

CLUTCH DISC

Inspect the clutch disc facings for

oil or grease. Eliminate the source of

any oil or grease before replacing the

disc. An excessive amount of grease in

the pilot bushing or release bearing

hub will find its way to the disc fac-

ings.
Too much lubricant in the trans-

mission or a plugged transmission

vent will force the transmission lubri-

cant out the input shaft and onto the

disc facings. Also, rear main bearing

oil seal leaks or oil leaks from the fly-

wheel mounting bolts can contaminate

the clutch disc.
Inspect the clutch disc for worn or

loose facings. Check the disc for worn

or loose facings. Check the disc for

distortion and for loose rivets at the

hub.
Check for broken springs.

Springs loose enough to rattle will not

cause noise when the car is operating.

Replace the disc assembly if any of

these defects are present. Be especially

careful when installing a new disc to

avoid dropping it or contaminating it

with oil or grease.

PILOT BUSHING

Check the fit of the clutch pilot

bushing in the bore of the crankshaft.

The bushing is pressed into the

crankshaft and should not be loose.

Inspect the inner surface of the bush-

ing for wear or a bell-mouthed condi-

tion. If the bushing is worn or dam-

aged, replace the bushing with a new

service bearing. Refer to the applica-

ble engine for the replacement proce-

dure.
