GENERAL DESCRIPTION
The regular production steering gear
is the
recirculat-
ing ball type. This gear provides
for
ease
of
handling
by
transmitting forces from worm
to
sector gear through
ball bearings.
The
steering linkage
is of
the relay type,
and extended interval lubrication design, with the pitman
arm connected
to one end of
the relay
rod. The
other
end
of
the
relay
rod is
connected
to an
idler
arm
which
is
connected
to the
frame side rail opposite
the
steering
gear.
Two
adjustable
tie
rods connect
the
relay
rod to
the steering arms.
All passenger
car
models
for 1967 are
equipped with
new energy absorbing steering columns.
The
mast jacket,
shift tube,
and
steering shaft
are
designed
to
collapse
under various front impact conditions.
All new
columns
are
of
this design, including
the
tilt option and telescope
option.
MAINTENANCE
AND
ADJUSTMENTS
The manual steering gear
is
filled
at the
factory with
a
water resistant grease. Seasonal change
of
this lubrica-
tion
is
unnecessary and
the
housing should
not be
drained.
The steering gear lubricant level should
be
checked every
36,000 miles. Whenever required, additions should
be
made using
a
water resistant
EP
chassis lubricant.
Check and fill steering gear
as
follows:
1.
Remove lower
and
outboard cover retaining screws
(fig.
1).
2.
Insert filling device
in
lower screw hole.
3.
Inject lubricant until
it
appears
in
outboard screw
hole; gear
is now
filled
to
correct level.
The steering linkage should
be
lubricated with water
resistant
EP
chassis lubricant every 6,000 miles
or six
months, whichever occurs first. Lubrication points
and
additional information
on the
chassis lubricant
to be
used
can
be
found
in
Section

STEERING
GEAR
Before any adjustments are made to the steering gear
in an attempt to correct such conditions as shimmy,
loose or hard steering etc., a careful check should be
made of front end alignment, shock absorbers, wheel
balance and tire pressure for possible cause.
Correct adjustment of the steering gear is very im-
portant. Perform adjustments following the sequence
listed below,
1.
Remove pitman arm nut and mark relation of pitman
arm position to sector shaft. Remove pitman arm
with Tool J- 6632 as shown in Figure 2.
2.
Loosen the pitman shaft lash adjuster screw locknut
and turn the adjuster screw a few turns in a counter-
clockwise direction (fig. 3). This removes the load
Fig. 2—Removing Pitman Arm
imposed on the worm bearings by the close meshing
of rack and sector teeth. Turn steering wheel gently
in one direction until stopped by gear, then back away
about one turn.
CAUTION: Do not turn steering wheel hard
against stops when steering relay rod is discon-
nected as damage to ball guides may result.
3.
All except Corvette and telescopic columns:
a. Disconnect steering column harness at chassis
wiring connector plug.
b.
Remove horn cap or ornament and using an inch
pound torque wrench and socket on steering wheel
nut, measure torque required to keep the wheel
in motion.

SECTOR SHAFT SEAL REPLACEMENT
A faulty seal may be replaced without removal of
steering gear from car by removing pitman arm as out-
lined under Maintenance and Adjustments--Steering Gear
Adjustments and proceed as follows:
1.
Loose lash adjuster lock nut and turn lash adjuster
screw several turns counterclockwise.
2.
Remove three cap screws holding side cover to gear
bushing.
3.
Pull side cover and sector shaft from gear housing
as a unit. Do not separate side cover from sector
shaft.
4.
Pull sector shaft seal from gear housing using
hooked tool or pliers.
5. Coat new seal with chassis grease and position in
sector shaft bore.
6. Place a socket or piece of pipe of suitable diameter
on top of seal and drive seal into bore by tapping
pipe or socket with soft hammer.
7. Install sector shaft side cover assembly, being care-
ful not to damage new seal with splines on end of
shaft; splines may be wrapped with a few turns of
tape to prevent this.
8. Install new side cover gasket and align side cover on
gear housing and install cap screw.
9. Perform steering gear adjustment and install pitman
arm as outlined under Maintenance and Adjustments.
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.

hand lamp until the string is positioned over the
crossarm centerline. Turn the screw clockwise
in making the final adjustment to take up play in
the headlamp mechanism.
Repeat the above procedure on the right-hand
lamp to complete the horizontal adjustment of the
headlamps.
VERTICAL ADJUSTMENT
8. a. Numeral "2" (fig. 5) should appear in the "down"
window of each aimer. If not, loosen knob at
underside of aimer arm and slide back and forth
until the numeral does appear.
NOTE:
This setting will give a 2" drop of the
headlamp high beam spot centerline on a screen
placed 25 feet forward of the vehicle. Check
state laws for proper vertical setting.
b.
Turn headlamp vertical aim screw (fig. 5) on left-
hand unit counter-clockwise until the bubble is at
the inner end of the glass tube. Then turn screw
clockwise until bubble is centered in tube.
c. Repeat this procedure on right-hand headlamp
unit to complete vertical adjustment of lamps.
9. Recheck the string at the ends of each crossarm for
correct setting and the bubble on each aimer for
centered position.
10.
Remove the aimers by pulling on the suction cup tabs
through the openings in the aimers (fig. 6).
11.
With headlamps properly aimed, replace headlamp
bezels.
HOW TO SELECT A LEVEL AIMING AREA
1.
Select area you believe to be level.
2.
Remove headlamp bezels and install Aimers on each
headlamp (fig. 3) making sure aiming lugs engage
smoooth inner ring of the Aimer.
"
To install Aimer,
press firmly on the knob extending out from the cen-
ter of the Aimer base. This forces the suction cup
into place on the Sealed Beam unit.:
3.
Loosen the slider knob beneath the aimer arm and
set the numeral "2" in the DOWN view window (fig.

4.
After botli bubbles are centered, turn the car around
end for end, making sure the tires are in the spots
made on the floor before the car was moved.
.5.
If the bubbles are still within the two outside black
marks on the vials, the floor is level enough to use
the Aimer as it comes from the factory.
NOTE:
A quick level check can be made by
using the T-3 Safety-Aimer as a level. Use
with a true eight to ten foot two by four as an
extension. Make sure pads on base of Aimer
are used. Place the board where you expect the
wheels to be and take readings as outlined above.
6. If either bubble moves outside the black lines of the
vial there is too much slant to the floor. Try driving
the car in at different angles onto the aiming area.
If bubbles can
not
be centered follow procedure under
"How to Compensate for Unlevel Floor."
NOTE:
When level portion of floor is obtained,
mark tire spots on floor so spots can be used
next time without calibrating Aimer.
TO COMPENSATE FOR UNLEVEL FLOORS
If your floor is not level within the limits specified, the
T-3 Aimer can be calibrated to compensate for the error
in the floor. Follow this procedure with both aimers.
1.
Drive the car onto the area for which you wish to
compensate the aimers, and install the aimers in
place on the headlamps.
2.
Loosen knob beneath the aimer arm and move the
slider until the bubble is centered.
3.
Record the numeral in the view window. (This nu-
meral is to be used only for recalibration.)
4.
Move the slider to a position halfway between this
recorded numeral and the numeral "2" in the
DOWN
window. (This numeral is used only in recalibration
and not for headlamp aiming.)
5.
Recalibrate aimers by turning screw shown in Figure
8 until the bubble is centered.
6. The T-3 Aimers are now calibrated for the selected
area. All future aiming must be done in the same
area and with the car pointed in the same direction.
Mark the tire spots on the floor so that other vehi-
cles can be located in the same position.
