Once the code number of the lock is obtained look up

this number in a key cutting book.

All side bar locks (except trunk) furnished to the field

by the Parts' Department are uncoded, that is, they are

furnished without tumblers, springs or spring retainers,

these parts are serviced separately. The tumblers come

in five different depths, indicated by numbers.

The side bar locks have six tumbler positions, and in

looking up the cutting code, the following may be used as

an example. After key code number is determined, either

from key or from number stamped on lock cylinder refer

to your code book and record the key cutting information

as follows:

545431

123456

NOTE:
Key blanks used for ignition and door

locks are stamped with an "A" while rear com-

partment and glove box blanks are stamped with

a "B".

The number that is written above the cutting or tumbler

position indicates each different tumbler which is to be

dropped into each tumbier slot of the lock.

In cases where a code book is not available, the dia-

gram shown on Figure 19 may be used to determine the

tumblers required to assemble an uncoded lock cylinder.

1.
Lay the key on the diagram (fig. 19) with bottom of

key flush with edge of the drawing, head and point

carefully lined up.

2.
Read the code in numbers 12345 from the head of the

key to the end from positions 1 to 6 inclusive. As

each depth is determined write that number in the

blank space provided above the position numbers

(1-2-3-4-5-6).

3.
With key properly lined up on diagram, all cuts that

show in the first section are marked
"1"

4.
Cuts that fall in the first black section, mark "2".

5. Cuts that fall in the first white section, mark "3".

6. Cuts that fall in second black section, mark "4".

7. Cuts that fall in the second white section, mark "5".

After the numbers have been determined and written

above the cutting positions the lock cylinder should be

assembled as follows.

Lock Cylinder Assembly—Refer to Figure 20

1.
Hold cylinder with head of cylinder away and starting

•... at the head of the cylinder, insert the tumblers in
their proper slots in the order called for by the

code, ribbed side toward you and long point down.

2.
After all tumblers are in place, check for correct-

ness with the code. Then press tumblers down with

one finger.

3.
Insert one tumbler spring in the space provided

above each tumbler.

CAUTION: If the springs are tangled, do not

pull them apart—unscrew them.

4.
Reverse the lock cylinder so that the head of the

cylinder is now toward you. Insert the spring re-

tainer so that one of its six prongs enters into each

of the springs and the two large end prongs slide into

the slots at either end of the cylinder. Press the

retainer down with one finger.

5. To check, insert proper key and if tumblers are in-

stalled properly the side bar will be allowed to drop

down. If bar does not drop down, remove the key,

spring retainer, springs and tumblers and reas-

semble correctly.

NOTE:
If the tumblers have not been assembled

correctly and not according to the code, the

tumblers can be removed from the cylinder by

holding it with the tumbler slots down, pulling

the side bar out with the fingers and jarring the

cylinder to shake the tumblers out. This pro-

cedure is necessary because after the tumblers

have been pressed down into the cylinder they

are held in their slots by the cross bar.

6. If after checking it is found that the lock is as-

sembled properly, remove key and place cylinder in

using a suitable staking tool at right angles to the

top of the retainer and from the cast metal of the

cylinder over the retainer at each corner.

PUSHING, TOWING AND LIFTING

Pushing

NOTE:
Towing car to start is not recommended

due to the possibility of the disabled car ac-

celerating into tow car.

AUTOMATIC TRANSMISSION

Do not attempt to start the engine by pushing the car.

Should the battery become discharged, it will be neces-

sary to use an auxiliary battery with jumper cables to

start the engine.

CAUTION: To prevent damage to electrical

system, never connect booster batteries in ex-
cess of 12 volts and connect positive to positive

and negative to negative.

Manual Transmission

When a push start is necessary turn off all electrical

loads such as heater, radio, and if possible, lights, turn

on the key, depress the clutch, and place the shift lever

in high gear. Release the clutch when your speed reaches

10 to 15 miles per hour.

TOWING

The car may be towed safely on its rear wheels with

the (selector lever in "N" (Neutral) position at speeds

of 35 miles per hour or less under most conditions.

However, the drive shaft must be disconnected or the

car towed on its front wheels if 1) Tow speeds in excess

of 35 MPH are necessary, 2) Car must be towed for ex-

tended distances (over 50 miles) or, 3) Transmission is

not operating properly. If car is towed on its front

wheels, the steering wheel should be secured to maintain

a straight ahead position.

TOWING THE CAMARO

The recommended method for towing the Camaro is

follows.

Front

Connect standard chain hooks near the outer ends of

the front suspension lower control arms in between the

coil springs and the stabilizer bar link bolt (fig. 23).

The chains should be attached to the lower lifting sling

bar so that when the vehicle is raised the rubber straps

protect the front valance panel (fig. 24). Caution should

be exercised when attaching the lower lifting bar that the

upper lifting bar does not damage the hood header panel.

Rear

Connect standard chain hooks around the axle tube from

the underneath side between the axle rear spring pad and

the brake flange plate (fig. 25). It is mandatory that the

chain hook be positioned as stated above so that the brake

lines are not damaged.

The lower lifting bar should be positioned in below the

vehicle so that the rubber straps protect the rear valance

panel. With the lower bar in this position, it is necessary

that the bar be spaced down a minimum of
1
5/8" to pre-

vent damage to the fuel tank. This can be accomplished

by placing 6.0" section of 2x4' wood blocks below the

rear section of each rear spring (fig. 26).

To facilitate towing without a helper it will be neces-

sary to attach the
2x4*
s to the rear spring by a strap or

tape.
See Figure 27.

Also it will be necessary to lock the steering wheel in

the straight ahead position prior to actually moving the

vehicle.

CORE

Fig. 2-Heater Schematic (Chevy 11)

CHEVY

Heater components are located under the instrument

panel in the passenger compartment. Hot water hoses

from the engine are routed to the fire wall to the heater

core pipes. The blower motor receives outside air from

the cowl vent plenum chamber through the adapter as-

sembly. The air enters the heater core chamber where

it either bypasses or passes through the core depending

on the position of the temperature door, controlled by

the TEMPERATURE lever on the instrument panel.

Temperature control is achieved by adjusting the position

of this door to vary the proportion of heated and unheated

air introduced to the car interior. As the air flow is

drawn out of the heater core chamber (in the desired

proportion of hot and cold), it enters the blower where

it is thoroughly mixed, assuring a uniform temperature.

The distributor guides the air flow through either the

floor outlet or the defroster outlets depending on the

setting of the DEFROSTER lever on the instrument

panel. The AIR-FAN lever is the air OFF control as

well as the blower control.

CONTROLS

Control Assembly (Chevrolet, Chevelle, Camaro,

and Chevy II)

Air-Fan Lever

Since the heater makes use of outside air only, this

lever serves as an "air on or off" control by actuating

a damper in the distributor assembly downstream ("up-

stream" in the Chevy n heater) from the blower assem-

bly. With the lever in the half-way position, this damper

will be open to allow airflow into the vehicle. Moving the

lever further will actuate the three-speed (LOW-MED-

HIGH) fan lever which controls the blower motor and

determines the volume and force of the air flowing

through the heater core into the car.

Temperature Lever

Through its bowden cable, this lever controls the
positioning of the temperature door in the distributor

duct. This door allows airflow through either the heater

core (full RIGHT) or the bypass duct around the heater

core (full LEFT). Because the water temperature is con-

stant, this knob acts as an air mixture control, control-

ling temperature by varying the proportions of heated

and unheated air blended in the heater distributor duct.

The cam lock device at the damper door operating

lever (Chevelle only) may be adjusted as follows: Loosen

the two attaching screws. Place the cam in the closed

position and insert a pin through holes provided, locking

the cam in this position. Rotate the entire assembly

toward the closed position. Hold closed with some force

and tighten attaching screws. Remove the locking pin.

Defrost Lever

The defrost lever controls the position of the damper

(or deflector) door located in the heater and defroster

assembly. In the "off" position full airflow will go to

the floor duct for car heating purposes. In the "de-ice"

position the diverter door will drop down and divert

almost all the airflow to the defroster duct. (This posi-

tion will seldom be needed except for extreme de-icing

requirements). A "detent" position is built into the

SYSTEM OPERATION

Compressor Suction and Discharge Connector

Compressor connector assemblies used on all vehicles

are of the same basic design consisting of the inlet

(suction) and outlet (discharge) connections, gauge fittings

and muffler and, in general, the assemblies differ only in

the location of the gauge fittings.

On Universal and Four-Season Systems the outlet line

extends along side of and toward the front of the com-

pressor and the muffler in the line is bracket mounted to

the compressor body. In all Universal Systems the gauge

fittings for both low and high pressure sides of the sys-

tem are located in the connector body. On Four-Season

Systems the high pressure gauge fitting is located on the

muffler and the low pressure gauge fitting is on the POA

Valve.

The Chevy n All-Weather System compressor con-

nector assembly is similar to the Universal System

connector assembly described above except that the

muffler extends straight out from the connector and

is not bracket mounted to the compressor.

Universal and Chevy II All-Weather System

1.
Install Gauge Adapter (J-5420 or J-9459) onto the

high and low pressure hoses of the gauge set.

2.
With the engine stopped, remove the caps from the

cored valve gauge, connectors on the compressor

fittings block.

3.
Connect the gauge lines with adapters to the threaded

connectors on the compressor fittings block.

Four-Season and Comfortron Systems

Installation of the gauge set onto the Four-Season and

Comfortron systems is accomplished in the same manner

as outlined above except that system performance checks

must be performed with the low pressure hose line and

adapter attached to the fitting on the POA valve. Charging

procedures should be performed with the high pressure

gauge line connected to the high pressure gauge fitting

located on the outlet line muffler and the low pressure

gauge line attached to the POA fitting.

CAUTION: When removing gauge lines from

the compressor fittings block be sure to remove

the adapters from the fittings rather than the

gauge lines from the adapters.

PERFORMANCE TEST

This test may be conducted to determine if the system

is performing in a satisfactory manner and should be

used as a guide by the serviceman in diagnosing trouble
