(13)Carry out hydraulic test.
Readjust as necessary.
REDUCING PRESSURE ADJUSTMENTh323FfADWhen multi-use tester is not used
(1) Following the same steps as those in line pressure
adjustment, remove parts up to oil filter.
There is no need to remove valve body.
(2) Turn adjusting screw of lower valve body to obtain the
specified reducing pressure. Turn it counterclockwise to
increase the pressure.
Standard value:425 f 10 kPa (60 f 1 psi)
Oil pressure change for
each turn of adjusting screw:45 kPa (6 psi)(3) In the same way as in line pressure adjustment,
/nstall oil
filter and oil pan.
(4) Perform hydraulic test.
Adjust as necessary.
When multi-use tester is used
(1) Adjust to obtain the specified K/D brake pressure when PC
solenoid is energized at duty 50% with the multi-use tester.
Standard value:275 kPa (39 psi)
Oil pressure change for
each turn of adjusting screw:50 kPa (7 psi)(2) After adjustment has been made, check that the recuding
pressure is in the range 360
- 480 kPa (51 - 68 psi).
Caution
This adjustment should be made with oil temperature70
- 80°C (160 - 180°F).
The adjustment made with high oil temperature couldresult in improper adjustment due to a line pressure
drop at idle.

2.If the deflection is out of the standard values, adjust the belt
tension using the following procedure.
(1) Loosen the tension pulley’s securing bolts A and
B.(2) Mount the extension bar on the tension pulley.
(3) While increasing the tension of the V-belt with the
extension bar, retighten the tension pulley’s securing
bolts A and B in the order mentioned.
FLUID LEVEL CHECKM37FlAJ
1.Park the vehicle on a flat, level surface, start the engine, and
then turn the steering wheel several times to raise the
temperature of the fluid to approximately 50
- 60°C (122 -
140°F).
2.With the engine running, turn the wheel all the way to the
left and right several times.
3.Check the fluid in the oil reservoir for foaming or milkiness.
Check the difference of the fluid level when the engine is
stopped, and while it is running. If the fluid level changes
considerably, air bleeding should be done.
FLUID REPLACEMENTM37FJAL1. Raise the front wheels on a jack, and then support them
with rigid racks.
2. Disconnect the return hose connection.
3. Connect a vinyl hose to the return hose, and drain the oil
into a container.
4. Disconnect the high-tension cable, and then while operat-
ing the starting motor intermittently, turn the steering
wheel all the way to the left and right several times to drain
all of the fluid.
Caution
Be careful not to position the high-tension cable nearthe carburetor or the delivery pipe.
5.Connect the return hoses securely, and then secure it with
the clip.
6.Fill the oil reservoir with the specified fluid up to the lower
position of the filter, and then bleed the air.
Specified fluid:MITSUBISHI PLUS ATF/Automatic
transmission fluid “DEXRON” or
“DEXRON II”

BLEEDINGM37FKAl
1.Jack up the front wheels and support them by using a floor
stand.
2. Manually turn the oil pump pulley a few times.
3. Turn the steering wheel all the way to the left and to the
right several times.
4. Disconnect the high-tension cable, and then, while operat-
ing the starting motor intermittently, turn the steering
wheel all the way to the left and right several times (for 15
to 20 seconds).
Caution1. During air bleeding, replenish the fluid supply so
that the level never falls below the lower position ofthe filter.
2. If air bleeding is done while engine is running, the
air will be broken up and absorbed into the fluid; besure to do the bleeding only while cranking.
5. Connect the ignition cable, and then start the engine
(idling).
6.Turn the steering wheel to the left and right until there are
no air bubbles in the oil reservoir.
7.Confirm that the fluid is not milky, and that the level is up to
the specified position on the level gauge.
8. Confirm that there is very little change in the fluid level
when the steering wheel is turned left and right.
Fluid level change:wlthln 5 mm 1.2 in.)I
9.Check whether or not the change in the fluid level is within

Irunning.
Caution

more, the air has not been completely bled from thesystem, and thus must be bled completely.
2. If the fluid level rises suddenly after the engine is
stopped, the air has not been completely bled.
3. If air bleeding is not complete, there will be
abnormal noises from the pump and the flow-
control valve, and this condition could cause a
lessening of the life of the pump, etc.

HEATERS AND MANUAL AIR CONDITIONER - safety Pre=utm55-9
SAFETY PRECAUTIONSR-12 refrigerant is a chlorofluoro-carbon
(CFC) that
can contribute to the depletion of the ozone layer in
the upper atmosphere.
Ozone filters out harmful radiation from the sun.
To assist in protecting the ozone layer, Mitsubishi
Motor Sales of America recommends that a R-12
refrigerant recycling device that meets SAE stan-
dard
J1991 be used.
Contact an automotive service equipment supplier
for refrigerant recycling equipment that is available
in your area.
The refrigerant used in all air conditioner is R-l 2. It is
transparent and colorless in both the liquid and
vapor state. Since it has a boiling point of
-29.8”C(-21.7”F), at atmospheric pressure, it will be a vapor
at all normal temperatures and pressures. The vapor
is heavier than air, non-flammable, and nonexplo-
sive. It is nonpoisonous except when it is in direct
contact with open flame. It is noncorrosive except
when combined with water. The following precau-
tions must be observed when handling R-12.
CautionWear safety goggles when servicing the refri-
geration system.R-12 evaporates so rapidly at normal atmospheric
pressures and temperatures that it tends to freeze
anything it contacts. For this reason, extreme care
must be taken to prevent any liquid refrigerant from
contacting the skin and especially the eyes. Always
wear safety goggles when servicing the refrigera-
tion part of the air conditioning system. Keep a
bottle of sterile mineral oil handy when working on
the refrigeration system. Should any liquid re-
frigerant get into the eyes, use a few drops of
mineral oil to wash them out. R-12 is rapidly
absorbed by the oil. Next splash the eyes with
plenty of cold water. Call your doctor immediately
even though irritation has ceased after treatment.
CautionDo not heat R-12 above 52°C
(125.6”F).
M55PAAFIn most instances, moderate heat is required to
bring the pressure of the refrigerant in its container
above the pressure of the system when charging or
adding refrigerant. A bucket or large pan of hot
water not over 52°C
(125.6”F) is all the heat required
for this purpose. Do not heat the refrigerant contain-
er with a blow torch or any other means that would
raise temperature and pressure above this tempera-
ture. Do not weld or steam clean on or near the
system components or refrigerant lines.
Caution
Keep R-12 containers upright when charging the
system.When metering R-12 into the refrigeration system,
keep the supply tank or cans in an upright position. If
the refrigerant container is on its side or upside
down, liquid refrigerant will enter the system and
damage the compressor.
CautionAlways work in a well-ventilated room.
Good ventilation is vital in the working area.
Although R-12 vapor is normally nonpoisonous,
contact with an open flame can cause the vapor to
become very poisonous. A poisonous gas is pro-
duced when using the flame-type leak detector.
Avoid inhaling the fumes from the leak detector.
CautionDo not allow liquid refrigerant to touch bright
metal.Refrigerant will tarnish bright metal and chrome
surfaces, and in combination with moisture can
severely corrode all metal surfaces.
