The headlamp panel travel is limited by two adjusting

screws which are located on the arms of the shaft

mounted stop.

9—Headlamp Panel Travel Adjusting Screw

1.
Raise hood and as a safety precaution install a bolt

through the hole in the hood support - secure bolt

with a nut.

2.
Adjusting screw (A) limits headlamp panel travel in

open position - adjust this screw so that mounting

face of panel is within 2 degrees of vertical in the

fully open position.

NOTE: Each headlamp operates independently

of the other, therefore individual adjustment is

required for each panel.

3.
Adjusting screw (B) limits headlamp panel travel in

closed position - adjust this screw so that panel is

flush to upper body panel in the fully closed position.

4.
Lock both screws by tightening lock nut against stop.

5.
Remove safety bolt as installed in Step 1 and close

the hood.

GENERAL DESCRIPTION

The Chevy
n
instrument cluster assembly consists
of:

a speedometer;
a
fuel gauge;
a
generator, temperature

and
oil
pressure indicator lamps, and includes
a
clock
on

deluxe models. Except
for the
speedometer,
all of the

cluster lamps, instruments and gauges
of
the cluster
may

be serviced without removing
the
instrument cluster
as-

sembly from
the
console.

In addition
to the
instrument indicator lamps,
a
brake

warning lamp
is
included
in the
cluster
as
standard

equipment.
The
indicator
is
connected
to
thfc parking

brake and brake pressure differential switches andserves
a dual function.
It
lights when
the
parking brake
is ap-

plied
and
also when
the
brake pedal
is
applied,
if a mal-

function should occur
in the
brake system
due to a
loss
of

hydraulic pressure. Servicing
of the
hydraulic pressure

differential switch
is
covered
in
Section
5 of
this manaul.

Regular maintenance
is not
required on
the
instrument

cluster
or its
components other than r^Mfitftl^i^g clean

and tight electrical connections, replacing defective parts

and keeping
the
speedometer cable properly lubricated.

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

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.
