STEERING WHEEL ALIGNMENT AND

HIGH POINT CENTERING

1.
Set front wheels in straight ahead position. This can

be checked by driving vehicle a short distance on a

flat surface to determine steering wheel position at

which vehicle follows a straight path.

2.
With front wheels set straight ahead, check position

of mark on wormshaft designating steering gear high

point. This mark should be at the top side of the shaft

at 12 o'clock position and lined up with the mark in

the coupling lower clamp.

3.
If gear has been moved off high point when setting

wheels in straight ahead position, loosen adjusting

sleeve clamps on both left and right hand tie rods,

then turn both sleeves an equal number of turns in

the same direction to bring gear back on high point.

CAUTION: Turning the sleeves an unequal
number of turns or in differential directions will

disturb the toe-in setting of the wheels.

4.
Readjust toe-in as outlined in Section 3 (if necessary).

5. With wheels in a straight ahead position and the

steering gear on highpoint, check the steering wheel

alignment by measuring the distance from each hori-

zontal spoke to the horizontal centerline of the

steering wheel (fig. 5). If the horizontal spokes are

over 1-1/8 inches from the horizontal position the

wheel should be removed and centered. (See steering

wheel removal in this section.)

TOE-IN ADJUSTMENT

Adjust the steering linkage for proper toe-in setting as

outlined in Section 3.

CORVETTE STEERING RATIO (Fig. 6)

The Corvette steering ratio may be changed as follows:

CAUTION: Do not use the rearward hole in the

steering arm with power steering equipment or

interference may result.

STEERING COLUMN

All models are equipped with new energy absorbing

steering columns. The columns are of five basic designs

as follows:

1.
Syncromesh. The syncromesh column is used on

models with standard, column mounted, conventional

shift levers. The shift tube, within the outer mast

jacket, includes two lower shift levers for connection

to the transmission control linkage.

2.
Automatic and floor shift. This column is used on

models equipped with column mounted powerglide

shift levers, or models with floor shift. If the ve-

hicle has the column mounted powerglide shift con-

trol, the inner shift tube has a single lower shift

lever for connection to the transmission control

linkage. On floor shift models, no lower shift levers

are present on the shift tube.

3.
Tilt wheel option. The upper end and steering shaft

of this column is specially designed to accommodate

the optional tilt steering wheel.

4.
Standard Corvette Column. The standard Corvette

column is similar in design to the Automatic and

Floor Shift column used on other models, except

no shift tube is used. Other differences are pointed

out in the disassembly and assembly procedures for

Standard Corvette column.

5. Telescopic wheel option. The upper end and steering

shaft of this column is specially designed to ac-

commodate the optional telescoping steering wheel.

To perform service procedures on steering column

upper end components, it is not necessary to remove the

column from the vehicle. The steering wheel, horn com-

ponents, turn signal switch, upper housing with bearing,

shift control lever, hazard warning knob, and upper shift

bowl may all be removed with the column remaining in

the vehicle. When servicing the above components, omit

the removal procedure and proceed with the applicable
disassembly procedures. Because of the numerous dif-

ferences in steering column types, be sure to refer to the

set of instructions below which apply to the exact column

to be serviced:

CAUTION: The outer mast jacket, shift tube, _

steering shaft, and instrument panel column

mounting b
racket

are designed as energy ab-

sorbing units. Because of the design of these

components, it is absolutely necessary to handle

the column with care when performing any serv-

ice operation required. Avoid hammering, jar-

ring, dropping, or leaning on any portion of the

column.

Removal

1.
Disconnect steering column harness at connector.

Disconnect neutral safety switch and back-up lamp

switch connectors if so equipped.

GENERAL DESCRIPTION

Two types
of
power steering
are
used
for 1967.
One
is

the conventional linkage type
for
Chevy
n and
Corvette

vehicles
and the
other
is the
integral gear type
for

Chevrolet, Chevelle,
and
Camaro.
For
both types
the

hydraulic pressure
is
provided
by an
engine-driven vane-

type pump.

On
the
Chevy
n and
Corvette linkage type power steer-

ing, hydraulic pressure
is
delivered through
a
hose from

the pump
to a
valve which senses
the
requirement
for

power assistance
and
supplies
the
power cylinder
ac-

cordingly.
The
steering gear used with this power steer-

ing
is the
same basic unit used
on
manually steered

vehicles;
it is
serviced
as
outlined
in the
manual steering

part
of
this section except
for
adjustment, which
is

covered
in the
following pages.
The
steering linkage also

is serviced the same
as
manual counterparts.

The Chevrolet, Chevelle
and
Camaro integral gear type

power steering
has the
hydraulic pressure delivered

from
the
pump through two hoses
to the
steering gear.
In
the power steering gear
the
steering shaft, hydraulic

valve, worm, and rack-piston
nut are all in
line making
a

compact
and
space saving assembly.
All oil
passages
are

internal within
the
gear except
the
pressure
and
return

hoses.

The steering gear
is a
recirculating ball system
in

which steel balls
act as a
rolling thread between
the

steering worm
and
rack-piston
nut. The
rack-piston
nut

is
all one
piece
and is
geared
to the
sector
of
the piston

shaft.
The
valve
is
contained
in the
gear housing elimi-

nating
the
need
of
bolts
or
seals
to
attach
a
separate

valve housing.

The valve
is an
open-center, rotary-type three
way

valve.
The
spool
is
held
in
neutral position by means
of a

torsion
bar. The
spool
is
attached
by
means
of
the stub

shaft
to one end of the
torsion
bar
and
to the
valve body

on
the
other
end.
Twisting
of the
torsion bar allows
the

spool
to
move
in
relation
to the
valve body thereby oper-

ating
the
valve.

MAINTENANCE
AND
ADJUSTMENTS

BLEEDING HYDRAULIC SYSTEM

1.
Fill
oil
reservoir
to
proper level and
let oil
remain

undistrubed
for at
least two minutes.

2.
Start engine
and run
only
for
about
two
seconds.

3.
Add
oil if
necessary.

4.
Repeat above procedure until
oil
level remains
con-

stant after running engine.

5. Raise front
end of
vehicle
so
that wheels
are off
the

ground.

6. Increase engine speed
to
approximately
1500 rpm.

7. Turn
the
wheels
(off
ground) right
and
left, lightly

contacting
the
wheel stops.

8. Add
oil if
necessary.

9. Lower
the car and
turn wheels right and left
on the

ground.

10.
Check
oil
level and refill
as
required.

11.
If oil is
extremely foamy, allow vehicle
to
stand
a

few minutes with engine
off and
repeat above

procedure.
,

a.
Check belt tightness
and
check
for a
bent
or
loose

pulley. (Pulley should
not
wobble with engine

running.)
b.
Check
to
make sure hoses
are not
touching
any

other parts
of the car,
particularly sheet metal.

c. Check
oil
level, filling
to
proper level
if
neces-

sary, following operations
1
through
10.
This

step
and
Step
"D" are
extremely important
as

low
oil
level and/or
air in the oil are the
most

frequent causes
of
objectionable pump noise.

d. Check
the
presence
of air in the oil. If air is

present, attempt
to
bleed system
as
described
in

operations
1
through
10. If it
becomes obvious

that
the
pump will
not
bleed after
a few
trials,

proceed
as
outlined under Hydraulic System

Checks.

FLUID
LEVEL

1.
Check
oil
level
in the
reservoir
by
checking
the dip

stick when
oil is at
operating temperature.
On

Chevelle models equipped with remote reservoir,

the reservoir should
be
maintained approximately

3/4 full when
oil is at
operating temperature.

2.
Fill,
if
necessary,
to
proper level with
GM
Power

Steering Fluid
or, if
this
is not
available, automatic
