5. To replace, reverse the removal procedure.

SPEEDOMETER REPLACEMENT

1.
Remove instrument cluster as previously described

in this section.

2.
Remove clock set shaft knob.

3.
Remove eight screws securing cluster housing to

bezel trim panel. Separate parts carefully observing

stack up of parts.

4.
Remove two screws securing speedometer head to

rear of cluster housing.

NOTE:
Servicing of the speedometer head

should be performed by an authorized AC Speed-

ometer Service Station.

5. To install, reverse the removal procedure..

SPEEDOMETER CABLE

Replacement or Lubricatibn

1.
Disconnect the speedometer cable from the speed-

ometer head. Remove the old cable by pulling it out

from speedometer end of conduit.

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

sary to remove lower piece from transmission

end of conduit.

2.
Lubricate the lower 3/4 of cable with speedometer

cable lubricant and push the cable into the conduit.

Connect the upper end to the speedometer head and

road test vehicle for proper speedometer operation.

INDICATOR LIGHT REPLACEMENT

To replace any indicator or cluster bulb, unsnap the

proper socket from rear of instrument cluster, remove

and replace bulb, and reinsert unit into rear of cluster

housing.

OIL PRESSURE INDICATOR

If the light does not come on when the ignition switch
is turned on, or if the light comes on and remains on

after the engine is started, one or more of the following

conditions is indicated:

• Low oil pressure

• High engine temperature

• Defective wiring or switch

Switch Replacement

1.
Disconnect wiring harness connector from sender

unit terminal (located in block above starter on

L-6 engines and at left front of distributor on V-8

engines).

2.
Remove sender unit, replace with new unit, and

; check operation.

GENERATOR INDICATOR

1.
Ignition on, engine not running and telltale light off.

a. Indicator bulb burned out, replace bulb.

b.
Open circuit or loose connection in the telltale

light circuit.

2.
Telltale light stays on after engine is started.

a. If indicator light does not go out at engine idle

speed, refer to Charging Systems under Engine

Electrical, Section 6Y.

TEMPERATURE (COOLING SYSTEM) INDICATOR

The temperature indicator circuit consists of two re-

motely located units, indicator gauge and engine sender

unit. The indicator gauge on all models uses a single

red light to indicate an overheated engine condition.

Engine Sender Unit Replacement

1.
Drain engine cooling system to a level below unit.

2.
Remove sender unit (located in the inlet manifold

near water pump housing on V-8 engines and in the

cylinder head near an exhaust port on L-6 engines)

and replace with new unit.

3.
Refill cooling system and check operation of unit.

GENERAL DESCRIPTION

All Corvette instruments and gauges are conveniently

located in the dash-mounted cluster. The entire cluster

is removable to permit servicing of the various instru-

ments and gauges. The indicator and cluster illuminating

bulbs may be replaced without removing the cluster from

the panel.
Regular maintenance is not required on the instrument

cluster or its components other than maintaining clean

and keeping the speedometer and tachometer cables

properly lubricated.

5. Remove the ignition switch. Refer to Section 6Y

for removal procedure. Then disconnect ignition

switch lamp support at instrument panel.

6. Disconnect oil pressure line at oil pressure gauge

then remove the lead wires from ammeter, wiper

switch and cigarette lighter. Disconnect trip odom-

eter at mast jacket support.

7. Remove the instrument cluster-to-dash retaining

screws and pull cluster assembly slightly forward

to obtain clearance for removal of speedometer

cable, tachometer cable, cluster ground wire, fuel

gauge lead wires and remaining indicator and cluster

illuminating lamps.

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.

CORVETTE

GENERAL DESCRIPTION

The 2-speed windshield wiper
(fig. 91)
consists
of a

compound wound
12
volt dc motor and
a
gear box section

containing
the
gear mechanism
and
relay control.
The

motor armature
is
fitted with
a
worm gear which drives

the main gear assembly and crank arm.

The relay control, consisting
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
mounted
on the
gear box

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

assembly (fig. 93).

port thereby supplying vacuum to the Servo unit.

During system operation
the
following events occur:

1.
Car
speed below
20
mph—no function
of the
unit

because
the
rubber drum
has
not rotated
far
enough

to close
the
solenoid points.
No
energizing current

can flow through the solenoid coil.

2.
Car
speed above
20
mph—The tang
on the
rubber

drum
has
closed
the
solenoid points
and
current
is

flowing through
the 40 ohm
resistance wire
to the

solenoid coil. This current
is
not sufficient to "pull

in", the solenoid.

3.
Driver partially presses Engagement Switch—full

voltage flows through
the
solenoid
to
pull
it
into

operation. Solenoid
cam
tension
on the "U"
clip
is

released and the clip grips the rubber drum. Simul-

taneously the vacuum switch operates; applying man-

ifold vacuum
to the
Servo unit which tightens
the

throttle chain. When
the
driver releases pressure

from
the
accelerator pedal
the
unit will position the

throttle
to
maintain the speed
at
the time
of
solenoid
operation.

Driver releases
the
Engagement Switch—current

flows
to the
solenoid through
the 40
ohm wire and

since the solenoid is "pulled in", the reduced current

flow
is
sufficient to hold
it
in position.

The
car
begins
to
ascend
a
hill—car speed drops

slightly (very slightly) and the magnetic force on the

driven disk
of the
speed sensor
is
decreased.
The

disk rotates slightly
(as
would
a
speedometer shaft

because
of
hairspring tension) turning
the
rubber

drum. Since
the "U"
clip
is
gripping
the
drum,
it

moves
the
slide which COVERS
the air
bleed ports

more. With less air bleeding into the Servo, greater

vacuum exists
in it
and the diaphragm moves toward

the vacuum port opening
the
throttle wider.
The

tapered needle moves into the orifice further and the

diaphragm balances
in a
new position with the wider

throttle opening.
Car
speed
has
been maintained

automatically.
