CENTERING CHECK

1.
Install a 0-2000 psi pressure

gauge Tool T56L-33610-D in the pres-

sure line between the power steering

pump outlet port and the integral

steering gear inlet port.

2.
Make sure that the valve on the

gauge is in the fully open position.

3.
Check the fluid level in the reser-

voir and fill it to proper level with the

specified fluid.

4.
Start the engine and cycle the

steering wheel from stop-to-stop, to

bring the steering lubricant up to nor-

mal operating temperature. Stop the
engine and recheck the reservoir. Add

fluid if necessary.

5.
With the engine running at ap-

proximately 1000 rpm and the steer-

ing wheel centered, attach an inch-

pound torque wrench to the steering

wheel retaining nut. Apply sufficient

torque to the torque wrench in each

direction, either side of center, to get

a gauge reading of 250 psi.

6. The torque reading should be the

same in both directions when 250 psi

is reached. If the difference between

the readings exceeds 4 in-lbs, the

steering gear must be removed and the

valve centering shim removed from the

valve housing and a thicker or thinner
shim installed. Only one shim is to be

used. If the steering effort is heavy,

the shim thickness should be in-

creased. Shim thickness should be de-

creased if the steering effort is light to

the left.

The out of vehicle procedure for

valve centering check is the same as

for the in vehicle except the torque

and simultaneous pressure reading

must be made at the right and left

stops instead of either side of center.

STEERING GEAR

ADJUSTMENTS

During the vehicle breaking-in peri-

od, it is probable that some of theprocarmanuals.com

factory adjustments will change. These

changes in adjustment do not neces-

sarily affect the satisfactory operation

of the steering gear assembly, and

therefore ordinarily do not require

readjustment unless there is excessive

lash or other malfunctioning.

ADJUSTMENT IN

VEHICLE

The only adjustment which can be

performed is the total over center

position load, to eliminate excessive

lash between the sector and rack

teeth.

1.
Disconnect the pitman arm from

the sector shaft.

2.

MAJOR REPAIR OPERATIONS

In most cases, complete disassembly

of the power steering gear will not be

necessary. It is suggested that only

those assemblies that are faulty be dis-

assembled. Disassembly and reassem-

bly of the unit and the subassemblies

must be made on a clean workbench.

As in repairing any hydraulically op-

erated unit, cleanliness is of utmost

importance. Therefore, the bench,
tools,
and parts must be kept clean at

all times. Thoroughly clean the exter-

ior of the unit with a suitable solvent

and when necessary, drain as much of

the hydraulic oil as possible. Handle

all parts very carefully to avoid nicks,

burrs,
scratches and dirt, which could

make the parts unfit for use. Do not

clean, wash or soak seals in cleaning

solvent.

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.

shaft and install and tighten the attach-

ing bolts to specification.

6. Connect and tighten the fluid
pressure and the return line to the

steering gear.

7. Fill the power steering pump and
cycle the steering gear. Check for

leaks.
Check the reservoir fluid level

again and add as required.

MAJOR REPAIR OPERATIONS

Disassembly and reassembly of the

unit and the subassemblies must be

made on a clean workbench. As in re-

pairing any hyldraulically operated

unit, cleanliness is of tftfiiost impor-

tance. Therefore, the bench, tools, and

parts must be kept clean at all times.

Thoroughly clean the exterior of the

gear with a suitable solvent and, when

necessary, drain as much of the hy-

draulic fluid from the gear as possible.

DISASSEMBLY INTO

SUB-ASSEMBLIES

1,
Mount the steering gear in a

vise.
(Fig..
2\

2.
Rotate the end plug retaining

ring to place one end of the ring

opposite the hole in the housing.
3.
Working through the hole in the

housing (Fig. 3), unseat the retaining

ring then work it out of the groove

with a screwdriver.

4.
Rotate the input shaft in a coun-

terclockwise direction using a 3/4

inch, 12-point socket wrench to force

the end plug out of the housing. Do

not rotate the shaft any more than

necessary to remove the plug. Further

rotation will allow the balls to fall

from their circuit and allow the rack-

piston to become disengaged from the

sector shaft. Remove the O-ring from

the housing and discard it.

5.
Rotate the input shaft 1/2 turn

in a clockwise direction to draw the

piston inward.

6. Turn the end plug (Fig. 4) count-

erclockwise out of the piston with a

1/2 inch drive extension.
7.
Remove the lock nut from the

sector shaft adjustment screw. Discard

the nut.

8. Remove the four cover attaching

screws. Rotate the sector shaft adjust-

ment screw with an Allen wrench until

the cover is free of the housing. Re-

move the cover and the O-ring. Dis-

card the O-ring.

9. Turn the input shaft as required

to center the sector shaft teeth in the

housing.

10.
Tap the end of the sector shaft

with a soft-faced hammer to free it

from the housing.

11.
Remove the adjuster plug lock

nut.

12.
Remove the adjuster p>ug with

spanner wrench T65P-3A537-A (Fig.

15).
