SERVO S,TEERING
Work which can be carried out with the servo
steering installed in the vehicle
NOTE:
The utmöst
clean liness should be observed
for all work on the power
steer
ing
equipment.
A
I-
ways
clean
the
connections
before
disconnecting
them, al50 the outside of the oil
container
before
removing its
cover.
O
nly
oil ATF, Type A or Dexron may be used for the
servo system.
CHECKING THE Oll lEVEL
The o
il
level
should be checked every
10000
km
(6000
miles).
The
level
sho
uld
first be
checked wi
th
the
engine
stationary in
order
to
see
whether
th
ere
has
been any
loss
of
oi!.
The
oil
level should th en
come
about
5-10
mm
(1;4")
above
th
e
level
marie
If th
e
level is lower than
this, fill
with oil with the
engine
stationary:
this will
eliminate risk
of
air
being
sucked
in
.
Start
the
engine and
the n
check
the oil level
again,
which
should
now fall to the maximum mark, see
Fig.
6-61.
When the
engine
has
stopped,
the oil level
may
rise to
5-10
mm
(1;4")
above
the level mark
.
DRAINING THE
Oll
With the
servo
steering pump
complete,
oil is drained
off as follows

.
Remove the cover on

Start the
eng
ine
and allow
it
to run
max.
10
seconds
until the
oil
is
emptied out of the conta
in
er and

FllLlNG WITH Oll AND VENTING
NOTE:
The oil
ca
pacity is
about
1.2
litres
(2.1
imp.
pints
=
2.5
US
pints).
Drained-off
oil,
may not be put
back into the
system.
1.
Fill
with oil up to the
edge
of the oil container.
2.
With
oil
wi
t
hin
easy
reach,
start
the
engine. Gra-
dually fill the
container
with oil
as
the level drops.
When the level has
stabihed
itself, proceed to the
next
operation.
3. Turn
the
steering
wheel repeatedly
and
evenly in
both
directions.
The
steering
wheel
should
be
turned
slowly so
that
the
pump opera·"es
at
low
pressure.
If necessary, fill with more oi!.
4.
Open
the venting screw
(7,
Fig.
6-62)
1/2-
1
turn.
Close
it when oil
starts
flowing
out.
5.
Continue
turning the
steering
wheel until the oil
in
the
container
is
practically free
from
air
bubbles.
6. Stop
the
engine. The
oil level
should
then rise
5-
10
mm
(1/4")
above
the level mark. If it rises
further than thi s, there must be
air
still in the
system,
in which
case continue
venting.
7.
Lower the front
end.
After the venting,
a small
number of
air
bubbles may
remain in the
system.
When
the pump
causes pressure
to be
applied
to the oil during driving, these
air
bubbles will
eventually
d isap
pear in the
container.
