HEATER AND AIR CONDITIONING 1A-3
linkage of this lever which will provide partial airflow
only to the defroster duct and which should be used for,
all normal defogging operations.
CORVETTE
Heater components are attached to the dash panel on
the right side of the vehicle with the air inlet assembly
on the engine side and the heater and air distributor
assemblies beneath the instrument panel within the pas-
senger compartment.
The heater operates on outside air only with the blower
receiving its air flow from the cowl vent plenum
chamber.
No water valve is utilized in the system. Therefore,
water flows through the heater core constantly while
the engine is running, keeping the core at maximum
temperature at all times.
Airflow through the system is shown in Figure 1.
Controls
Two knobs control all heater operations:
The FAN-TEMP knob is rotated to turn the blower
on and off and control blower speed and is pulled out
as desired to regulate heater temperature.
The AIR-DEF knob is the air on-and-off control as
well as the defroster control.
Temperature Damper: Door
At the heart of the heater operation is the temperature
damper door. Air from the blower follows parallel paths
through the distributor duct, with one path passing
through the heater core and the other path bypassing the
core.
The temperature damper door is placed in the duct
so that, when closed, the path of the heated air leaving
the heater core is blocked while the ambient air path
remains open. Positive closing of this door when no
heat is being called for is assured by a cam assembly
at the door operating lever. As the FAN-TEMP knob
is pulled out, the damper door is opened accordingly,
allowing varying proportions of heated air to mix with
the unheated airflow, thus providing heater outlet tem-
perature control. With the knob pulled fully out the
Fig.
4—Heater Controls (Corvette)
ambient air path is blocked and all airflow passes
through the heater core. Final heater output temperature
is dependent upon the proportion of heated and ambient
air blended together according* to the setting of the
temperature damper door.
Air and Defrost Damper Doors
Beyond the temperature damper door are the air door
and the defroster door, both operated through a single
bowden cable by the AIR-DEF knob. The first half of the
travel of this knob opens the AIR door allowing the
airflow to pass into the interior of the car through the
floor distributor openings. Pulling the AIR-DEF knob
fully out causes the defroster door to open, diverting
this airflow to the defroster ducts for defogging, de-
frosting or deicing operations.
NOTE: Since this knob is the air on-or-off
control, it should be pulled at least halfway out
before turning on the blower.
Fan Control
Rotate the FAN-TEMP knob to operate the three-
speed blower, increasing the velocity of the air through
the heater. The fully counter-clockwise position of the
knob is the off position. Turn clockwise to the desired
blower speed; fully clockwise for high blower speed.

GENERAL DESCRIPTION
The 1967 Chevrolet, Chevelle, Camaro, Chevy n and
Corvette front suspension systems are basically similar,
being of the
S.L.A.
(short-long arm) type with independent
coil springs. In the Chevrolet, Chevelle, Camaro and
Corvette the springs ride on the lower control arms; in
the Chevy II the springs ride on the upper control arms.
Spherical joints connect the upper and lower arms to the
steering knuckle. Tapered roller wheel bearings are
used.
Camber angle is adjusted, on the Chevrolet and Chevy n
CHEVROLET CHASSIS SERVICE MANIM
FRONT SUSPENSION 3-6
Fig.
8 - Caster and Camber Adjustments - Chevy
To adjust for caster and camber, loosen the upper sup-
port shaft to crossmember nuts, add or subtract shims as
required and retighten nuts.
NOTE:
Caster and camber can be adjusted in
one operation.
Caster and camber specifications will be found in the
last section of this book.
Chevrolet and Chevy II
The caster angle is adjusted by turning the two niits at
the front of the lower control arm strut rod (figs. 7 and
8).
Shortening this rod will increase caster. Lengthen-
ing will decrease caster.
Camber angle is adjusted by loosening the lower con-
trol arm pivot bolt and rotating the cam located on this
pivot. This eccentric cam action will move lower control
arm in or out, thereby varying camber.
Steering Axis Inclination Adjustment
"Camber" is the outward tilt of the wheel and "steering
axis inclination" is the inward tilt of the knuckle. Cam-
ber cannot be changed without changing steering axis
inclination. Correct specifications willbe found at the
end of this section. If, with the camber correctly ad-
justed, the steering axis inclination does not fall within
the specified limits the knuckle is bent and should be
replaced.
If a new knuckle is installed, caster, camber and toe-in
must be readjusted.
Toe-In Adjustment
Toe-in, the inward pointing of both front wheels, is
checked with the wheels in the straight ahead position. It
is the difference of the distance measured between the
extreme front and the distance measured between the ex-
treme rear of both front wheels. Correct toe-in specifi-
cations will be found at the end of this section.
NOTE:
Toe-in must be adjusted after caster
and camber adjustment.
A. If the equipment being used measures the toe-in of
each wheel individually:
1.
Set the steering gear on the high point, mark 12
o'clock position on the steering shaft and position
the steering wheel for straight ahead driving.
2.
Loosen the clamp bolt at each end of each tie rod
and adjust to the total toe-in as given in the speci-
fications at the end of this book.
B.
If a tram gauge is being used, proceed as follows:
1.
Set the front wheels in the straight ahead position.
2.
Loosen the clamp bolts on one tie rod and adjust
for the proper toe-in as given in the specifications
at the end of this book.
3.
Loosen the clamp bolts on the other tie rod. Turn
both rods the same amount and in the same direc-
tion to place the steering gear on its high point and
position the steering wheel in its straight ahead
position.
C.
After the adjustment has been made:
1.
a. Chevrolet—Position inner tie rod clamp bosses
forward to 90° down to avoid stabilizer link bolt
interference.
b.
Chevelle—Position the tie rod clamp bosses
down to 45?° forward to avoid interference.
c. Chevy II--Position the outer tie rod clamp
bosses forward and not more than 45° up or
down from horizontal to avoid interference.
Inner clamps forward and vertical.
d. Corvette--Position inner tie rod clamps with
bolt horizontal and down. Position outer clamps
with bolt vertical and to the rear.
e. Camaro—Position inner tie rod clamps with
open end of clamp and slot in line. Position
relative to ground unimportant. Position outer
clamps with bolt top and 30° either side of ver-
tical. Position relative to slot unimportant.

REPAIR PROCEDURES
Unless otherwise indicated all repair procedures will
apply to all five vehicles covered in this manual.
CAUTION: During any operations which in-
clude breaking the ball stud loose from the
knuckle boss extreme care must be used to as-
sure that the ball stud seal is not damaged or
cut. A recommended way to loosen the stud is to
place a flat bar stock against the knuckle boss
and strike the bar rather than the knuckle.
FRONT BRAKE DRUM-CHEVROLET, CAMARO,
CHEVELLE, CHEVY It
Removal
1.
Remove hub caps, partially loosen wheel nuts and
raise vehicle from floor. Remove wheel nuts and
wheel.
2.
Remove brake drum. In some cases it may be nec-
essary to back off brake adjustment because of
scored drum or unevenly worn brake linings.

bolts and hub pilot diameter.
2.
Install wheel and partially tighten wheel nuts.
3.
Re-adjust brake shoes to original setting. It may be
necessary to re-adjust brake shoes on both front
and/or rear wheels to assure balanced brake adjust-
ment. See Section 5 for brake adjustment procedure.

Remove the hub bolts with a press or hammer.
These bolts are not peened into the hub. Do not
damage wheel mounting surface on hub flange.
2.
Install new serrated bolt into hole in
hub.
Tap lightly
with a hammer to start bolt serrations in hole, mak-
ing sure that bolt is square with hub flange.
3.
Press bolt into flange until head is fully seated
against hub flange (fig. 10).
FRONT WHEEL BEARINGS

ommended that vehicle be raised and supported on a
twin-post hoist so that the front coil spring remains com-
pressed, yet the wheel and steering knuckle assembly re-
main accessible. If a frame hoist is used, support lower
control arm with an adjustable jackstand to safely retain
spring in its curb height position.
