IN-VEHICLE ADJUSTMENTS AND REPAIRS

STEERING WORM AND

SECTOR

GEAR ADJUSTMENTS

The ball nut assembly and the sec-

tor gear must be adjusted properly to

maintain minimum steering shaft end

play (a factor of preload adjustment)

and minimum backlash between sector

gear and ball nut. There are only two

possible adjustments within the recir-

culating ball-type steering gear, and

these should be made in the following

order to avoid damage or gear failure.

1.
Disconnect the Pitman arm from

the steering Pitman-to-idler arm rod.

2.
Loosen the nut which locks the

sector adjusting screw (Fig. 3), and

turn the adjusting screw counterclock-

wise.
(On models equipped with the

Cobra Jet engine, it may be necessary

to use a suitable holding tool with an

extension and a long screwdriver to

make the gear adjustment).

3.
Measure the worm bearing pre-

load by attaching an in-lb torque

wrench to the steering wheel nut (Fig.

4).
With the steering wheel off center,

read the pull required to rotate the

input shaft approximately 1 1/2 turns

either side of center. If the torque or

preload is not within specification

(Part 3-1), adjust as explained in the

next step.

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

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.

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.
VALVE CENTERING

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.

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.

IN-VEHICLE ADJUSTMENTS AND REPAIRS

HOISTING INSTRUCTIONS

Damage
to
steering linkage compo-

nents
and
front suspension struts
may

occur
if
care
is
not
exercised when
po-

sitioning
the
hoist adapters
of 2
post

hoists prior
to
lifting
the
vehicle.

If
a 2
post hoist
is
used
to
lift
the

vehicle, place
the
adapters under
the

lower arms
or
the No. 1
crossmember.

Do
not
allow
the
adapters
to
contact

steering linkage.
If the
adapters
are

placed under
the
crossmember,
a
piece

of wood (2x4x16 inches) should
be

placed
on the
hoist channel between

the adapters. This will prevent
the

adapters from damaging
the
front
sus-

pension struts.
