8. To install cluster in dash panel, reverse removal

procedure.

FUEL GAUGE

The gasoline fuel gauge circuit consists of an electri-
cal indicator in the instrument cluster and a float-

controlled rheostat in the fuel tank.

Since the fuel gauge consists of two remotely located

units and connecting wires, it is sometimes difficult to

determine which unit is at fault when the gauge fails to

operate properly. Cluster removal is necessary to re-

place the fuel gauge.

NOTE:
Be sure to check gas gauge fuse in fuse

panel before attempting to trouble shoot for

inoperative gauge or tank sending unit.

SPEEDOMETER AND/OR TACHOMETER

Removal and Installation

Cluster must be removed from vehicle to service

speedometer head assembly (see Cluster Removal pro-

cedure)
.
With cluster removed from vehicle:

1.
Remove five screws securing cluster back panel to

cluster assembly; separate the parts carefully.

CAUTION: Care must be used to avoid marring

instrument cluster face.

2.
Remove two screws securing speedometer or ta-

chometer head to cluster back panel; carefully re-

move speedometer or tachometer head.

NOTE:
Servicing of speedometer or tachom-

eter head should be performed by an authorized

AC service station.

3.
Reverse above procedure to install speedometer.

Cable Replacement or Lubrication

1.
Disconnect the. cable from the speedometer or ta-

chometer head. Remove the old cable by pulling it

out from speedometer end of conduit.

NOTE:
If old cable is broken it may be nec-

essary to remove lower piece from transmission

or distributor end of conduit as applicable.

2.
Lubricate the lower 3/4 of cable with
AC
speedom-

eter cable lubricant and push the cable into the con-

duit. Connect the upper end to the speedometer or

tachometer head and road test vehicle for proper

operation.

TEMPERATURE GAUGE

The temperature indicator requires very little service

other than testing for malfunctioning and replacing de-

fective units. Cluster must be removed to service tem-

perature gauge.

Do not attempt to repair either the engine unit or the

gauge. When installing new engine unit, do not use

thread compound on unit threads, as this will increase

electrical resistance of unit and cause faulty reading

on gauge.

AMMETER OR OIL PRESSURE GAUGE

The ammeter or oil pressure gauge requires very

little attention other than keeping ammeter terminals

clean and tight. If the oil pressure control line should

become restricted it should be blown out or replaced.

Cluster must be removed to service these gauges.

GENERAL DESCRIPTION

The standard Camaro instrument cluster assembly con-

sists
of two
circular units which house
the
speedometer

and fuel gauge assemblies.
The oil
pressure, left-hand

directional
and
brake warning indicators
are
located
in

the face
of the
speedometer bezel while generator,
tem-

perature
and
right-hand directional indicators are grouped

with
the
fuel gauge unit.
The
high beam indicator
is

located between
the
cluster bezels.

A special instrumentation package
is
available with
the

eight-cylinder engine
and
center floor console combina-

tion.
The
special cluster includes:
a
clock; coolant

temperature,
oil
pressure, fuel
and
ammeter gauges,

mounted forward
on the
seat separator console;
a ta-

chometer
in the
right circular housing
of the
dash
in-

strument cluster; and
a low
fuel level indicator replacing

the
oil
pressure indicator lamp
in the
instrument cluster.

The instruments
and
gauges,
may be
serviced only

after
the
instrument cluster
is
removed from
the
vehicle.

Indicator
and
cluster lamps except
for the
high beam

indicator
may be
replaced without removing
the
cluster

assembly. Partial cluster removal
is
necessary when

replacing
the
high beam indicator due
to its
proximity
to
the upper brace
rod
anchor plate.
The
bulbs
are in-

stalled
in
plastic sockets which lock into
the
cluster

housing and make contact with
the
printed circuit.

A
low
level fuel warning system
is a
special feature

available with
the
floor console gauge pack. This
sys-

tem includes
an
indicator lamp
in the
dash cluster and
a

semi-conductor unit senses
the
change
in
electrical
re-

sistance
of the
fuel system circuitry
as
variations
in

fuel level occur.
The
sensing device
is
replaced
as a

unit
if
found defective.

The brake warning light serves
a
dual purpose.
It

functions
as an
indicator when
the
parking brake
is ap-

plied
and
also
if
there
is a
malfunction (loss
of
hydraulic

pressure)
in the
brake system. Switches which provide

the signal
to
operate
the
light
are
located
at the
parking

brake assembly
and at the
brake master cylinder
in the

hydraulic lines. Service
of the
brake pressure differ-

ential switch unit
is
covered
in
Section
5 of
this manual.

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 properly lubricated.

of a
relay coil, relay
armature
and
switch assembly,
is
located in the gear
box"

section and controls the starting and stopping of the wiper

through
a
latching mechanism (fig. 92).

An electric .washer pump
is

section
of the
wiper
and is
driven by the wiper unit gear

assembly (fig. 93).

WIPER ASSEMBLY REPAIRS

The overhaul procedures for the wiper are broken down

into three major areas: The motor section, gear box

section and washer pump section. Each section may be

serviced independently of the other.

MOTOR SECTION

Disassembly

1.
Remove the two motor tie bolts.

2.
Remove the armature end-play adjusting screw (fig.

91).

3.
Strike the steel case lightly with a mallet to partiaUy

loosen it from the die casting housing and motor

field.

4.
Insert a tool through the armature adjusting screw

opening and push against the end of the armature

shaft to back off the case. This will retain the ar-

mature commutator in position between the brushes

until ready to separate the armature from the case.

5.
To separate armature from case while still retaining

the brush springs and brushes in place fashion a

spring similar to that shown in Figure 95 and insert

behind the brush leads as shown.
Fig.
95 - Retaining Armature Brushes

6. Pull the armature out of the case and remove the felt

washer, thrust plate, and rubber thrust disc from the

case assembly bearing as required.

7.
The field windings are pressed into the gear housing

and further disassembly is not recommended; how-

ever, the field leads may be unsoldered from the

brush holders to remove the case.

8. Clean and inspect all parts.

Inspect both the field and armature for damage

due to overheating such as unsoldered electrical

connections.

Check that brush leads are firmly attached both

to the brushes and their connections at the brush

holders.

Check brushes for wear. If brushes are worn to

within 3/16" of brush lead, or pigtail, they should be

replaced.

Check contacts of circuit breaker shown at top of

Figure 95. Clean as required or file lightly to re-

move irregularities.

Inspect all leads from the brush and circuit

breaker plate for worn insulation or tjreaks.

If it was determined by inspection that brush re-

placement was required, proceed as follows:

a. Remove retainer installed during disassembly and

remove brush springs.

b.
Place a hot soldering iron against*brush lead con-

nection on brush holders, remove old bushes, and

nection on brush holders, remove old brushes,

and install new brushes.

c. To reinstall brushes in holders, compress spring

within holder and hold fully compressed with a

thin instrument inserted through the slot in the

brush holder. Then push brush into holder with

lead upward to project through slot in holder, hold
