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.
