GENERAL INFORMATION
0-6

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:

Key of Lock

Code Number

0V11

Cutting or Tumbler

position from head

of lock
Key Cutting

Code Numerical

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"
J

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

The selection of the proper lubricant and its correct

application at regular intervals does much to increase the

life and operation of all moving parts of the vehicle.

Consequently, it is important that the correct grade of

oil or grease, as noted in the following pages, be used.

ENGINE CRANKCASE OIL

Crankcase Capacity

4 Cylinder 4 qt.

6 Cylinder 4 qt.

8 Cylinder (283) 4 qt.

8 Cylinder (327) 4 qt.

8 Cylinder (350) 4 qt.

8 Cylinder (396) 4 qt.

8 Cylinder (427) Chevrolet 4 qt.

8 Cylinder (427) Corvette 5 qt.

For 4 Cyl. Add .5 qt. with filter change;

1 qt. for 6 and 8 Cyl. engines.

Lubrication

Crankcase oil should be selected to give the best per-

formance under the climatic and driving conditions in the

territory in which the vehicle is driven.

During warm or hot weather, an oil which will provide

adequate lubrication under high operating temperatures

is required.

During the colder months of the year* an oil which will

permit easy starting at the lowest atmospheric tempera-

ture likely to be encountered, should be used.

When the crankcase is drained and refilled, the crank-

case oil should be selected, not on the basis of the exist-

ing temperature at the time of the change, but on the

lowest temperature anticipated for the period during

which the oil is to be used.

Unless the crankcase oil is selected on the basis of

viscosity or fluidity of the anticipated temperature, dif-

ficulty in starting will be experienced at each sudden

drop in temperature.
SAE Viscosity Oils

SAE Viscosity Numbers indicate only the viscosity or

body of the oil, that is, whether an oil is a light or a

heavy body oil, and do not consider or include other

properties or quality factors.

The lower SAE Viscosity Numbers, such as SAE 5W

and SAE 10W which represent the light body oils, are

recommended for use during cold weather to provide

easy starting and instant lubrication. The higher SAE

Viscosity Numbers such as SAE 20 and SAE 20W, which

represents heavier body oils, are recommended for use

during warm or hot weather to provide improved oil

economy and adequate lubrication under high operating

temperatures.

Oils are available which are designed to combine the

easy starting characteristics of the lower SAE Viscosity

Number with the warm weather operating characteristics

of the higher SAE Viscosity Number. These are termed

"multi-viscosity oils," SAE 5-10W, SAE 5W-20, SAE

10W-20W, and SAE 10W-30.

The following chart will serve as a guide for the

selection of the correct SAE Viscosity Number for use

under different atmospheric temperature ranges, and

suggests the appropriate SAE Viscosity Numbers when

multi-viscosity oils are used.

GENERAL DESCRIPTION

Four
air
conditioning systems
are
covered
in
this

section. They are:

1.
The
Four-Season System (Chevrolet, Chevelle,

Camaro and Corvette).

2.
The Comfortron System (Chevrolet).

3.
The All Weather System (Chevy n).

4.
The Universal System (Chevrolet, Chevelle, Chevy
n,

Camaro)

Underhood components (that
is, the
compressor,
con-

denser
and
receiver-dehydrator)
are
much
the
same
in

type,
location
and
method
of
attachment
on all of
the

above systems. The six-cylinder reciprocating compres-

sor
is
bracket-mounted
to the
engine
and
belt driven

from
the
crankshaft pulley.
The
condenser
is
mounted

ahead
of the
engine cooling radiator
and the
receiver-

dehydrator
is
mounted
in
the refrigerant line downstream

of
the
condenser.
All
cooling system components
are

connected by means
of
flexible refrigerant lines.

Evaporator size
and
location differ from system
to

system
as do
methods
of
temperature control
and air

supply
and
distribution.

FOUR-SEASON SYSTEM

The Four-Season system used
in the
Chevrolet,

Chevelle, Camaro,
and
Corvette vehicles
may be
iden-

tified
by the
fact that
it
uses
an
evaporator pressure

control known
as the POA
(Pressure Operated Absolute)

suction throttling valve.
Both
the
heating
and
cooling functions
are
performed

by this system.
Air
entering
the
vehicle must pass

through
the
cooling unit (evaporator)
and
through
(or

around)
the
heating unit,
in
that order, and the system
is

thus referred to
as a
''reheat" system.

The evaporator provides maximum cooling
of the air

passing through
the
core when
the air
conditioning sys-

tem
is
calling
for
cooling.
The
control valve acts in the

system only
to
control
the
evaporator pressure
so
that

minimum possible temperature
is
achieved without core

freeze-up.
The
valve
is
preset,
has no
manual con-

trol,
is
automatically altitude compensated,
and non-

repairable.

The heater core will be hot
at
all times since no water

valve
is
present
in
the system.

System operation
is as
follows (See Figure 24 and 25):

Air, either outside
air or
recirculated
air
enters
the

system
and is
forced through
the
system by the blower.

As
the air
passes through
the
evaporator core,
it

receives maximum cooling
if
the
air
conditioning controls

are calling
for
cooling. After leaving
the
evaporator,

the
air
enters
the
Heater
and Air
Conditioner Selector

Duct Assembly where,
by
means
of
manually operated

diverter doors,
it is
caused
to
pass through
or to
bypass

the heater core
in the
proportions necessary
to
provide

the desired outlet temperature. Conditioned airflow then

enters
the
vehicle through either
the
floor distributor

duct
or the
dash outlets. Remember that the heater core
