1. DESCRIPTION
The steering gear is a rack and p i n i o n type
which is mounted on the lower section of the engine
compartment bulkhead by rubber mountings and
brackets.

The design of this assembly requires a range of
special tools to dismantle and assemble the steering
gear. If the steering gear is found to have a fault which
requires overhaul of the rack and pinion, it is recom-
mended that this be performed by an authorized work-
shop or steering specialist.

However, the procedures for the removal and
installation of the steering gear and the renewal of the
tie rods, the tie rod ends and the rubber boots are fully
covered in this section.

The rack and pinion assembly requires no lubri-
cation during service.

The steering column is of the energy absorbing
type designed to compress in the event of a severe
front end collision. The energy absorbing units are the
outer steering column, the tilt bracket and the steering
shaft. All these units shoul d be handled with extreme
care if service operations are performed on the
steering column assembly.

(3) Remove the steering wh eel retaining nut and
mark the steering shaft and steering wheel hub in
relation to each other as an aid to assembly.
(4) Remove the steering wheel from the steering
shaft.
NOTE: If the steering wheel will not sepa-
rate from the steering shaft, loosen the horn
pad retaining screws at the rear of the
steering wheel and withdraw the horn pad
after disconnecting the wire. A puller can
now be used to pull the steering wheel from
the steering shaft. Do not strike the end of
the steering shaft as sharp blows can cause
irreparable damage to the collapsible steer-
ing shaft.

(5) If necessary the steering wheel can be dis-
mantled as shown in the illustration.

Installation is a reversal of the removal procedure
with attention to the following points:

(1) Apply a light coat of multipurpose grease to
the horn slip ring and the turn signal canceling pins.
(2) Ensure that the marks on the steering wheel
and steering shaf t are aligned.
(3) Tighten the steering wheel retaining nut to
the specified torque.

206 Electrical System
Install the armature and yoke to the drive end
bracket rotating the drive to align the reduction gears.
Do not use force.
Install the retaining through bolts to the
commutator end bracket and lighten the through bolts
and armature end cover retaining screws securely. Install the solenoid to the drive end bracket,
install the retaining screws and tighten them securely.
Install the brush connector strap and
install
the retaining nut and washer and tighten securely.
9 . IGNITION SYSTEM

The testing and repair procedures for the ignition
system are fully covered in the Fuel and Engine
Management section.

10. STEERING WHEEL
The removal and installation procedures for the
steering wheel and horn pad are fully covered in the
Steering section.

11. SWITCHES AND CONTROLS
IGNITION SWITCH
To Remove and Install
Disconnect the negative battery terminal.
Remove the retaining screws from the steer-
ing column cover. Unclip and separate the upper and lower
steering column covers and remove the upper cover. Release the column adjusting lever and re-
move the lower cover by guiding the column adjusting
lever through the hole in the upper end of the cover.

Disconnect the ignition switch wiring at the
switch. Remove the retaining screw and withdraw
the ignition switch fr om the lock assembly.
Installation is a reversal of the removal procedure.

COMBINATION SWITCH
The combination switch is mounted at the top of
the steering column and incorporates two switches.
The parking lamp, headlamp, headlamp flasher, head-
lamp dipper and turn signal lamps are operated by a
lever on the right hand side. A lever on the left hand
side operates the windscreen washer and wiper switch.

These switches can be re newed without removing
the combination switch.

To Remove and Install Switches
Remove the retaining screws from the steer-
ing column cover.
Unclip and separate the upper and lower
steering column covers and remove the upper cover.

vehicle.
Release the column adjusting lever and re-
move the lower cover by guiding the column adjusting
lever through the hole in the upper end of the cover. Disconnect the wiring connectors from the
applicable switch. Remove the retaining screws located at the
top and bottom of the applicable switch and remove
the switch. Installation is a reversal of the removal procedure.

To Remove and Install Combination Switch Base
Disconnect the negative battery terminal.
Remove the steering wheel as described in
the Steering section Remove the retaining screws from the steer-
ing column cover. Unclip and separate the upper and lower
steering column covers and remove the upper cover.
Release the column adjusting lever and re-
move the lower cover by guiding the column adjusting
lever through the hole in the upper end of the cover.

216 Electrical System

NOTE: While checking the operation of the
fusible link, loosely connect the battery-
terminal only, to safeguard against damage
to the wiring harness.

(5) If the circuit is still inoperative or the fusible
link burns out again, refer the problem to an auto-
motive electrician.

RELAY LOCATIONS
The various relays employed in the vehicle elec-
trical system are located behind the fusible links
adjacent to the washer bottle in the engine compart-
ment, on the engine compartment bulkhead, under
the windscreen wiper motor and in the fuse box at the
lower right hand side of the dashboard.

The engine compartment relays power the radia-
tor fan, horn, condenser fan, bulb check, automatic
transaxle neutral safety switch, air conditioner and
condenser motor.

The fuse box relays power the fuel pump, ignition,
some accessories and the el ectronic control module.

18. TRAILER WIRING
There are several brands of trailer wiring connec-
tors available with a variet y of pin configurations. The
most common is the seven pin type which provides
for two auxiliary circuits, usually used for reverse
lamps and electric trailer brakes.
