Engine compartment wiring harness incorporates sev-

eral fusible links. Each link is identified with its gage

size. A fusible link is a length of special wire (normally

four wire gages smaller than the circuit it is protecting)

used in wiring circuits that are not normally fused, such

as the ignition circuit. The same size wire with a hypalon

insulation must be used when replacing a fusible link.

The links are:

1.
The pigtail lead at the battery positive cable (except

Corvette) is a 14 gage, brown fusible link protecting

the 10 gage battery charging circuit. This wire is an

integral part of the battery cable assembly and serv-

icing requires replacing the complete battery cable

assembly. On Corvette models this link is installed

as a molded splice at the solenoid "Bat" terminal

and servicing requires splicing in a new link.

2.
A 16 gage black fusible link is located at the horn
4.
relay to protect all unfused wiring of 12 gage or

larger. It is installed as a molded splice and serv-

icing requires splicing in a new link.

The generator warning light and field circuitry (16

gage wire) is protected by a fusible link (20 gage

orange wire) used in the "battery feed to voltage

regulator #3 terminal" wire. The link is installed as

a molded splice in the generator and forward lamp

harness and is serviced by splicing in a new 20 gage

wire as required.

The ammeter circuit on all models is protected by

two orange, 20 gage wire fusible links installed as

molded splices in the circuit at the junction block or

the solenoid "Bat" terminal (Corvette only) and at

the horn relay. Each link is serviced by splicing in a

new 20 gage wire as required.

MAINTENANCE AND ADJUSTMENTS

At regular intervals, inspect the terminals for cor-

rosion an4 loose connections, and the wiring for frayed

insulation. Check mounting bolts for tightness. Check the

drive belt for alignment, proper tension and wear. Be-

cause of the higher inertia and load capacity of the rotor

used in A.C. generators, PROPER BELT TENSION is

more critical than on D.C. generators.

Since the Delcotron and its companion regulator are

designed for use on negative polarity systems only, the

following precautions must be observed. Failure to ob-

serve these precautions may result in serious damage to

the charging system.

1.
When installing a battery, always make absolutely

sure the ground polarity of the battery, generator and

regulator is the same.

2.
When connecting a booster battery, make certain to

connect the correct battery terminals together.

3.
When connecting a charger to the battery, connect the

correct charger leads to the battery
%
terminals.

4.
Never operate the generator on an uncontrolled open

GENERAL DESCRIPTION

20 GALLON TANK

Fig.

—Corvette Fuel Tanks

The Corvette
is
equipped with
a
standard
20
gallon

(approx.) tank
or an RPO 36
gallon (approx.) fiberglass

tank
(fig. 21). The
tanks
are
installed
at the
very rear

of
the
vehicle, convenient
for
direct fuel filling into
the

tank.
The
tanks
are
held
in
place
by
two metal straps
at-

tached individually
to a
removable
gas
tank frame
sup-

port.
Two
guides
at the end of
the straps
are
adjustable

for securing
the
straps onto
the
tank support. The tank

support
is
secured
to the
frame rail with flat washers,

lockwashers, bolts
and
nuts.
The
tanks' rest
on six
felt

anti-squeak pads.
One pad
centers
on the
rear frame

crossmember
and one at
each side
on the
same cross-

member.
At the
same rear location two pads
are
placed

on
the
tank
at the
metal support strap (rear) attachment
location
and
another anti-squeak
pad
cemented
on the

support
at
the front
of
the tank.

The fuel tanks
are
equipped with
a gas
gauge metering

unit,
a
fuel pickup, fuel strainer
and
vent line.
If it be-

comes necessary,
the
tank
can be
completely drained
by

removing
the
fuel pickup hose which
is
located
at
the
bot-

tom
of the
tank,
or
by removing the metering
for
quicker

draining.

A pressure vacuum type, positive vented design
cap,

conforming
to
I.C.C. regulations,
is
used on both regular

production
and
optional fuel tanks.
The cap is
inter-

changeable with past model tanks
for
service replace-

ment purposes.

SECTOR SHAFT SEAL REPLACEMENT

A faulty seal may be replaced without removal of

steering gear from car by removing pitman arm as out-

lined under Maintenance and Adjustments--Steering Gear

Adjustments and proceed as follows:

1.
Loose lash adjuster lock nut and turn lash adjuster

screw several turns counterclockwise.

2.
Remove three cap screws holding side cover to gear

bushing.

3.
Pull side cover and sector shaft from gear housing

as a unit. Do not separate side cover from sector

shaft.

4.
Pull sector shaft seal from gear housing using

hooked tool or pliers.

5. Coat new seal with chassis grease and position in

sector shaft bore.

6. Place a socket or piece of pipe of suitable diameter

on top of seal and drive seal into bore by tapping

pipe or socket with soft hammer.

7. Install sector shaft side cover assembly, being care-

ful not to damage new seal with splines on end of

shaft; splines may be wrapped with a few turns of

tape to prevent this.

8. Install new side cover gasket and align side cover on

gear housing and install cap screw.

9. Perform steering gear adjustment and install pitman

arm as outlined under Maintenance and Adjustments.

STEERING COLUMN

All models are equipped with new energy absorbing

steering columns. The columns are of five basic designs

as follows:

1.
Syncromesh. The syncromesh column is used on

models with standard, column mounted, conventional

shift levers. The shift tube, within the outer mast

jacket, includes two lower shift levers for connection

to the transmission control linkage.

2.
Automatic and floor shift. This column is used on

models equipped with column mounted powerglide

shift levers, or models with floor shift. If the ve-

hicle has the column mounted powerglide shift con-

trol, the inner shift tube has a single lower shift

lever for connection to the transmission control

linkage. On floor shift models, no lower shift levers

are present on the shift tube.

3.
Tilt wheel option. The upper end and steering shaft

of this column is specially designed to accommodate

the optional tilt steering wheel.

4.
Standard Corvette Column. The standard Corvette

column is similar in design to the Automatic and

Floor Shift column used on other models, except

no shift tube is used. Other differences are pointed

out in the disassembly and assembly procedures for

Standard Corvette column.

5. Telescopic wheel option. The upper end and steering

shaft of this column is specially designed to ac-

commodate the optional telescoping steering wheel.

To perform service procedures on steering column

upper end components, it is not necessary to remove the

column from the vehicle. The steering wheel, horn com-

ponents, turn signal switch, upper housing with bearing,

shift control lever, hazard warning knob, and upper shift

bowl may all be removed with the column remaining in

the vehicle. When servicing the above components, omit

the removal procedure and proceed with the applicable
disassembly procedures. Because of the numerous dif-

ferences in steering column types, be sure to refer to the

set of instructions below which apply to the exact column

to be serviced:

CAUTION: The outer mast jacket, shift tube, _

steering shaft, and instrument panel column

mounting b
racket

are designed as energy ab-

sorbing units. Because of the design of these

components, it is absolutely necessary to handle

the column with care when performing any serv-

ice operation required. Avoid hammering, jar-

ring, dropping, or leaning on any portion of the

column.

Removal

1.
Disconnect steering column harness at connector.

Disconnect neutral safety switch and back-up lamp

switch connectors if so equipped.

Remove nuts and washers securing flanged end of

column to steering gear. On Chevy H models, re-

move nut and clamp bolt securing lower end of steer-

ing column to steering gear.

Disconnect transmission control linkage, if so

equipped, from lower column shift tube, levers.

Chevrolet and Chevy II only: Remove screws at-

taching upper and lower mast jacket covers together.

On Chevrolet, remove screws attaching lower cover

to instrument panel (figs. 15 and 18). Remove lower

cover.

Chevelle only: Remove screws securing mast jacket

trim cover to instrument panel and remove cover

(fig. 15).

Corvette, only: Remove screws securing escutcheon

to instrument panel. Remove screws securing upper

and lower covers together and remove covers.

On Chevrolet and Chevelle columns with Powerglide

shift levers, loosen set screw at six o'clock position

at bottom of column and remove the transmission

shift indicator pointer (fig. 15).
