FIELD RELAY CHECKS AND ADJUSTMENT
To check for a faulty relay proceed as follows:
1.
Connect a voltmeter into the system at the regulator
No.
2 terminal to ground (fig. lie).
2.
Operate the engine at fast idle (1500 to 2000 rpm) and
observe voltmeter reading.
3.
If voltmeter shows zero voltage at regulator, check
circuit between No. 2 terminal on regulator to "R"
terminal on Delcotron.
4.
If voltage at regulator exceeds closing voltage
Fig.
13c—Adjusting Field Relay Closing Voltage
specification and light remains on, regulator field
relay is faulty (Refer to specifications). Check and
adjust regulator as follows:
CLOSING VOLTAGE ADJUSTMENT
•1.
Make connections as shown in Figure 12c using a 50
ohm variable resistor.
NOTE: This gives us a variable resistance in
series from a hot lead to the relay coil.
2.
Turn resistor to "open" position.
3.
Turn ignition switch off.
4.
Slowly decrease resistance and note closing voltage
of the relay. Adjust by bending heel iron in the man-
ner illustrated in Figure 13c.
OTHER HARNESS CHECKS
Other wires in the charging system harness need be
checked for continuity by use of an ohmmeter or a test
ligjit (12 Volt). Connect the test so the wire in question is
in series in the test circuit.

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
0 --
General Information
and
Lubrication.

required for proper steering gear alignment.
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.

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.
