2) Lift vehicle and remove jack-up plate.
3) Remove one pipe joint at the center of gearbox, and
connect vinyl hose to pipe and joint. Discharge fluid by
turning steering wheel fully clockwise and counterclock-
wise. Discharge fluid similarly from the other pipe.
CAUTION:
Improper removal and installation of parts often
causes fluid leak trouble. To prevent this, clean the
surrounding portions before disassembly and
reassembly, and pay special attention to keep dirt and
other foreign matter from mating surfaces.

A: REMOVAL
1) Remove ground cable from battery.
2) Drain the working fluid about 0.35
(0.4 US qt, 0.3 Imp
qt) from oil tank.
3) Remove pulley belt cover bracket.

4) Loosen oil pump pulley nut, then remove bolts which
secure alternator.
5) Loosen pulley belt(s).
6) Remove the nut and detach oil pump pulley.

7) Remove bolt A. Disconnect pipe C from oil pump. Dis-
connect pipe D from oil tank.
CAUTION:

Do not allow fluid from the hose end to come into
contact with pulley belt.

To prevent foreign matter from entering the hose
and pipe, cover the open ends of them with a clean
cloth.

Except when only oil tank needs to be inspected,
detach oil tank and oil pump as a unit. Then separate
one from the other on a work bench to prevent oil from
spilling on any part of the engine.

1) Feed the specified fluid with its level being about 5 cm
(2.0 in) lower than the mouth of tank.
2) Continue to turn steering wheel slowly from lock to lock
until bubbles stop appearing in the tank while keeping the
fluid at that level.
3) In case air is absorbed to deliver bubbles into piping
because the fluid level is lower, leave it about half an hour
and then do the step 2) all over again.
4) Start, and idle the engine.
5) Continue to turn steering wheel slowly from lock to lock
again until bubbles stop appearing in the tank while keep-
ing the fluid at that level.
It is normal that bubbles stop appearing after three times
turning of steering wheel.
6) In case bubbles do not stop appearing in the tank, leave
it about half an hour and then do the step 5) all over again.
7) Stop the engine, and take out safety stands after jack-
ing up vehicle again.
Then lower the vehicle, and idle the engine.
8) Continue to turn steering wheel from lock to lock until
bubbles stop appearing and change of the fluid level is
within 3 mm (0.12 in).
9) In case the following happens, leave it about half an
hour and then do step 8) again.
(1) The fluid level changes over 3 mm (0.12 in).
(2) Bubbles remain on the upper surface of the fluid.
(3) Grinding noise is generated from oil pump.
