-35. INSTALLATION OF SPACER
(1) Apply a thin coat of engine oil to the outer circumfer-
ence of the spacer.
(2) Install the spacer with the chamfered end facing the oil
seal.
NOTEIf the spacer is installed adversely, the oil seal may be
damaged, resulting in the oil leaks.
33. INSTALLATION OF TIMING BELT “B”
(1) Ensure that crankshaft sprocket “B” timing mark and
the silent shaft sprocket timing mark are aligned.
(2) Fit timing belt “B” over crankshaft sprocket “B” and
the silent shaft sprocket. Ensure that there is no slack inthe belt.
.ADJUSTMENT OF TIMING BELT “B” TENSION
(1) Temporarily fix the timing belt “B” tensioner such that
the center of the tensioner pulley is to the left and
above the center of the installation bolt, and temporarilyattach the tensioner pulley so that the flange is toward
the front of the engine.
(2) Holding the timing belt “B” tensioner up with your
finger in the direction of the arrow, place pressure on
the timing belt so that the tension side of the belt is
taut. Now tighten the bolt to fix the tensioner.
Caution
When tightening the bolt, ensure that the tensioner
pulley shaft does not rotate with the bolt. Allowing
it to rotate with the bolt can cause excessive
tension on the belt.
(3) To ensure that the tension is correct, depress the belt
(point A) with a finger. If not, adjust.
Standard value: 5-7 mm
(.20-.28 in.)

NOIROA~U6. REMOVAL OF OIL PRESSURE SWITCH
(1) Remove the oil pressure switch terminals.
(2) Using the special tool, remove the oil pressure switch.
CautionSince sealant is coated on the thread area, be
careful not to break it.
9. REMOVAL OF OIL PAN
(1) Remove the all oil pan bolts.
(2) Drive in the special tool between the cylinder block and
oil pan.
NOTE
Never use a screwdriver or chisel, instead of the special
tool, as a deformed oil pan flange will result, resulting inoil leakage.
18. REMOVAL OF PLUG CAP
Using the special tool, remove the plug cap.
20. REMOVAL OF DRIVEN GEAR BOLT
(1) Remove the plug on the side of cylinder block.
(2) Insert a Phillips screwdriver [shank diameter 8 mm
(.32in.)] into the plug hold to block the silent shaft.
(3) Remove the driven gear bolt that secures the oil pump
driven gear to the silent shaft.

Fine
7LUOOO76LUO12OIL PRESSURE SWITCH
-1
(1) Connect a tester (ohm range) between the terminal and thebody and check for conductivity. If there is no conductivity,
replace the switch.
(2) Next insert a very fine wedge through the oil hole, pushing
it slightly. There should be no conductivity (resistance
should be infinite). If there is conductivity even when
wedge is pushed, replace the switch.
(3) Or, if there is no conductivity when a 50
kPa (71 psi)
pressure is placed through the oil hole, the switch is
operating properly. Check at this time to see that there is
no air pressure leakage. If there is air pressure leakage, thediaphragm is broken, and the switch should be replaced.
OIL COOLER BYPASS VALVE (Turbo)
NaacNA
(1) Make sure that the valve moves smoothly.
(2) Ensure that the dimension
L measures the standard value
under normal temperature and humidity.
Dimension
L: 34.5 mm (1.358 in.)
(3) The dimension must be the standard value when measuredafter the valve has been dipped in
100°C (212°F) oil.
Dimension
L: 40 mm (1.57 in.) or more
OIL PUMP
NOBRCGG(1) Assemble the oil pump gear to the front case and rotate it
to ensure smooth rotation with no looseness.
(2) Ensure that there is no ridge wear on the contact surface
between the front case and the gear surface of the oil
pump cover.
(3) With the drive and driven gears installed into the front case.Standard value:
Drive gear
0.16-0.21 mm (.0063-.0083 in.)

(2) Apply a 4 mm (.I 6 in.) wide bead of sealant to the entirecircumference of the oil pan flange.
Specified sealant:
MITSUBISHI GENUINE PART No.
MD9971 10 or
equivalent
(3) The oil pan should be installed in 15 minutes after the
application of sealant.
(4) Note the difference in bolt lengths at the location
shown.8. INSTALLATION OF OIL PRESSURE SWITCH
(1) Coat sealant on the thread area, and using the special
tool, install the pressure switch.
Specified sealant: MOPAR Part No.4318034
orequivalent
Caution
1. Do not let sealant ooze out of the top of the
thread area.
2. Do not overtighten the pressure switch.
(2) Install the oil pressure switch terminals.
5. INSTALLATION OF OIL COOLER
First insert the oil cooler projecting stopper in the oil filter
bracket groove and then tighten the oil cooler bolts.lu3. INSTALLATION OF OIL FILTER
Wipe clean the mounting surface on the filter bracket.
Then, apply a thin coat of engine oil to filter O-ring and
