FEATURE

*
This
ABS
5
.3i
type
incorporates
the
hydraulic
control
unit,
ABS
control
module,
valve
relay
and

motor
relay
in
one
unit
for
betterproductivity
and
lightweight
.

*
The
ABS
(Anti-lock
brake
system)
electrically
controls
brake
fluid
pressure
to
prevent
wheel

"lock"
during
braking
on
slippery
road
surfaces,
thereby
improving
directional/steering
stability
as

well
as
shortening
the
braking
distance
.

*
If
the
ABS
becomes
inoperative,
the
fail-safe
system
activates
to
ensure
it
acts
asa
conventional

brake
system
.
The
warning
light
also
comes
on
to
indicate
that
the
ABS
is
malfunctioning
.

"
The
front-and-rear
wheels

:
the
front

A
system
which
independently
controls

*2
:
A
system
which
provides
the
same

for
the

19) Support transmission with a garage jack.
CAUTION:
Before moving engine away from transmission, check
to be sure no work has been overlooked. Doing this is
very important in order to facilitate re-installation and
because transmission lowers under its own weight.

(1) Place the transmission with case left side facing
downward and put ST1 on bearing cup.
(2) Screw retainer assembly into left case from the bot-
tom with ST2. Fit ST3 on the transmission main shaft.
Shift gear into 4th or 5th and turn the shaft several
times. Screw in the retainer while turning ST3 until a
slight resistance is felt on ST2.
This is the contact point of hypoid gear and drive pin-
ion shaft. Repeat the above sequence several times to
ensure the contact point.

(3) Remove weight and screw in retainer without
O-ring on the upper side and stop at the point where
slight resistance is felt.
NOTE:
At this point, the backlash between the hypoid gear and
drive pinion shaft is zero.

(4) Fit lock plate
11. Loosen the retainer on the lower
side by 1-1/2 notches of lock plate and turn in the
retainer on the upper side by the same amount in order
to obtain the backlash.
NOTE:
The notch on the lock plate moves by 1/2 notch if the plate
is turned upside down.
(5) Turn in the retainer on the upper side additionally
by 1 notch in order to apply preload on taper roller
bearing.
(6) Tighten temporarily both the upper and lower lock
plates and mark both holder and lock plate for later
readjustment.
(7) Turn transmission main shaft several times while
tapping around retainer lightly with plastic hammer.
(8) Set ST1 and ST2. Insert the needle through trans-
mission oil drain plug hole so that the needle comes in
contact with the tooth surface at a right angle and check
the backlash.

1) Adjust tire pressure to specifications.
2) Set vehicle under“curb weight”conditions. (Empty lug-
gage compartment, install spare tire, jack, service tools,
and top up fuel tank.)
3) Set steering wheel in a wheel-forward position.
4) Suspend thread from wheel arch (point“A”in figure
below) to determine a point directly above center of
spindle.
5) Measure distance between measuring point and center
of spindle.
