protect owners, automobile lock manufacturers stamp

the lock numbers on the lock core, shaft, etc., where they

will not show until lock is removed.

In addition, when a lock cylinder requires replacement

the lock code number may be obtained either from the

key, if available, or from old lock cylinder which is being

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

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

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.

Fig.
24—Towing Sling Attachment—Front

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.

mounting brackets.

CLUTCH LINKAGE ADJUSTMENT

There is one linkage adjustment (clutch fork push rod

or pedal push rod) to compensate for all normal clutch

wear.

The clutch pedal should have
1-1/4"
free travel (meas-

ured at clutch pedal pad) before the throwout bearing en-

gages the clutch diaphragm spring levers. Lash is re-

quired to prevent clutch slippage which would occur if the

bearing was held against the fingers and to prevent the

bearing from running continually until failure.

Chevrolet Linkage Adjustment (Fig. 1}

With Nuts (A) & (B) loose on Rod (D)
&
before installa-

tion of Clutch Pedal Return Spring
(E),
apply approximately

5 lbs. load in direction of arrow (F) to eliminate clear-

ance between throwout bearing and clutch fingers. Move

Rod (D) in direction of arrow (G) until Clutch Pedal Arm

makes contact with Bumper Stop on instrument panel

brace. Run Nut (B) toward Swivel until dimension (X) is

9/32". Tighten Nut (A) to lock Swivel (C) against Nut (B).

Install Clutch Pedal Return Spring (E).

The foregoing procedure will provide a free pedal

travel of 1" to
1-1/2"
measured on a perpendicular from

the crown of the, pedal pad to the bare metal toe pan.

Chevelle Linkage Adjustment (Fig. 2)

1.
Disconnect spring between cross shaft lever and

clutch fork.

2.

3.
If there is no free travel, shorten the rod (by turning

at square wrench area) until it is free of clutch fork.

4.
Hold the clutch fork rearward to move throwout

lightly against clutch release fingers, then adjust rod

length until rod just touches ,its seat in the fork.
5.
Adjust locknut to obtain approximately 3/16" clear-

ance between nut and rod sleeve end.

6. Turn the rod with wrench, until the nut just comes in

contact with rod sleeve end, then hold the rod with

wrench and tighten locknut.

7.
Check free pedal travel at pedal (1" to
1-1/2"
is

proper clearance). Readjust if necessary.

chined flat "B". (Shorten push rod to increase pedal

lash).

2.
Hold push rod at flat "B" and tighten locknut "A".

3.
Recheck pedal free travel.

NOTE: A measurement of approximately 3/16"

between push rod and its seat in fork will give

required pedal free travel.

V-8 Models

The eight cylinder linkage has a two-piece clutch fork

push rod (fig. 3). Adjust clutch pedal free travel by turn-

ing the adjusting rod portion of the push rod to obtain apr

proximately 3/16" clearance between clutch fork and end

of rod, ttien tighten locknut to 8-12 lbs. ft. and check free

travel at pedal. Pedal free travel on all models should

be 1" to
1-1/2".
