lifted on the rim to force the top tire bead

against the top rim flange. The weight of the

tire will seat the bottom bead.

Repair

When a tire loses all or most of its air pressure,

particularly when driving at high legal speeds on today1 s

super-highways, recommended procedure is to remove it

from the wheel for complete inspection to be sure no

tire damage has occurred. Punctured tires should be

removed from the wheel and permanently repaired from

the inside.

Externally applied plug type repairs should be con-?

sidered temporary and the tire should be permanently

repaired as soon as possible.

Hot Patch Method

It is essential to thoroughly clean and remove all

foreign matter from the hole left by the puncturing-object

without enlarging the injury and then follow the manu-

facturer's instructions for vulcanizing the patch.

Rubber Plug Methods

There are several types of rubber plugs--some are

inserted from the inside of the tire; others are inserted

from the outside of the tire without demounting the tire

from the rim.

When using the plug method be sure to clean and

lubricate the hole with repair cement before inserting

the plug. Your tire supplier has available complete kits

containing materials, tools and detailed instructions for

making repairs with plugs. Follow instructions in the kit

you use.

Cold Patch Method

(Self Vulcanizing Type)

In this method it is essential to thoroughly clean and

remove all foreign matter from the hole left by the

puncturing object without enlarging the injury; also on

the inside of the tire, buff an area large enough for the

patch. Follow the manufacturer1 s instructions for appli-

cation of the special cement and self-vulcanizing cold

patch.
Pressure Gun Method

Several types of pressure guns are available. Consult

your tire supplier for materials and instructions.

Tire Installation Safety Precautions

When tires are mounted on dirty or corroded rims, or

when they are not properly centered on rims, the tire

bead may "bind" on the rim, and refuse to seat. Allowing

pressure to continue to build up within the assembly in

an attempt to seat the tire bead is a DANGEROUS PRAC-

TICE which can result in a broken tire bead, and serious

injury to the serviceman.

1.
Make sure that rim flanges and bead ledge (espe-

cially hump and radius) areas are smooth and clean.

Remove any oxidized rubber, dried soap solution,

rust, heavy paint, etc. with a wire brush, or, in ex-

treme cases, a file.

2.
Lubricate tire beads, rim flanges, and bead ledge

areas with a liberal amount of thin vegetable oil

soap solution, or approved rubber lubricant,

3.
Insure that air pressure build-up during the bead

seating process is not allowed to exceed 40 pounds

pressure. If beads have not seated by the time pres-

sure reaches 40 pounds, assembly should be deflated,

re-positioned on rim, re-lubricated and re-inflated.

4.
Make sure valve core is inserted in valve stem

prior to inflating.

5.
Use an extension gauge with clip on chuck so air

pressure build-up can be closely watched and so

that you can stand well back from the assembly

during the bead seating process.

HEADLAMP ADJUSTMENT-

T-3 HEADLAMPS

CAUTION: Check and tighten radiator support

grille retaining bolts prior to attempting head-

lamp aiming. Distorted grille or supports in

this area will hinder proper aiming of head-

lamps. On Corvette models make sure head-

lamp panel is adjusted properly - refer to

"Headlamp Panel Travel Adjustment".

When aiming headlamps, vehicle should be filled to ca-

pacity with gas, oil, and water but no load. Tires should

be uniformly inflated to recommended pressure.

the T-3 Safety Aimer-Type B (fig. 2), is used for the

headlamp aiming description that follows. An adapter is

required with the Type B T-3 Aimer when adjusting the 7

inch headlamp used on the Chevy n vehicle.

1.
Drive vehicle onto selected aiming area. Bounce

vehicle several times and allow to settle.

2.
Remove headlamp bezels.

3.
Mount the T-3 Aimers on either the No. 1 or No. 2

pair of headlamps so that "the points of the headlamps

engage the smooth inner ring of the aimers.

NOTE:
Moisten suction cups slightly to obtain

5. With both aimers in place, knot both ends of elastic

string and, using slots provided, fasten string across

horizontal crossarms of each aimer.

6. Rotate both aimers so that the string just clears the

points on the crossarms.

GENERAL DESCRIPTION

The standard instrument cluster on all models contains

seven circular housings consisting of: a speedometer;

fuel gauge; oil pressure, generator and temperature indi-

cators; right and left directional signal indicators; brake

warning and high beam indicators; and includes a clock

on deluxe models. An optionally available instrument

cluster provides special instrumentation which includes

in addition to the speedometer and clock: a tachometer;

fuel, oil pressure, ammeter and engine temperature

gauges; which replace the standard fuel gauge and indi-

cator lights. The brake warning indicator is relocated

to the tachometer dial face and the high beam and direc-

tional indicators are positioned in the speedometer dial

face.

Instrument cluster removal is recommended before at-

tempting to service the printed circuit and gauges even

though some units may be accessible from behind the

cluster. Limited working space under the instrument

panel increases the possibility of electrical malfunctions

due to poor connections, and damaged or improperly in-

stalled printed circuit. The printed circuit is service-

able but not repairable and requires complete
replacement.

The brake warning light serves a dual purpose. It

functions as an indicator when the parking brake is ap-

plied and also warns if a malfunction (loss of hydraulic

pressure) should occur in the brake system. The two

separate switches, which provide the signal to operate the

indicator, are located at the parking brake support and in

the hydraulic brake line at the master cylinder. Service

of the brake pressure, differential switch unit at the

master cylinder is described in Section 5 of this manual.

All indicator and cluster illumihating lamps may be

replaced without removing the cluster from the vehicle.

The bulbs are installed in plastic holders which lock into

the cluster housing and make contact with the printed

circuit. An instrument lamp is used to illuminate the

ignition switch. A special fibre optic lucite wiring

transmits light from the lamp to the switch.

Regular maintenance is not required on the instrument

cluster or its components other than maintaining clean,

tight electrical connections, replacing defective parts and

keeping the speedometer cable properly lubricated.
