(1) Operation check
Using a hand
vaccum pump, apply a negative pressure to
the solenoid valve nipple on which the white vacuum hose
is connected, and check air-tightness when the voltage is
applied to the solenoid valve terminal and when it i‘s releasedfrom the terminal.

(1) Remove the air bypass valve.
(2) Connect the hand vacuum pump to the nipple of the air
bypass valve.
(3) Apply a negative pressure of approx. 53.3 kPa (7.7 psi), andcheck operation of the valve. Also check that air tightness
is maintained.

13. DISCONNECTION OF POWER STEERING OIL PUMP
Disconnect the oil pump with hoses from the bracket.
NOTE
The removed power steering oil pump should be fastened
(by using rope, etc.) in a position that will not interfere with
the removal/installation of the turbocharger assembly.

29. REMOVAL OF TURBOCHARGER ASSEMBLY
Remove the turbocharger assembly with the exhaust fitting,water
pipe A, water pipe 6 and the oil pipe attached to it.3B.REMOVAL OF OIL PIPE
CautionAfter disconnecting the oil pipe, take care that foreign
material does not enter the oil passage hole of the
turbocharger assembly.
INSPECTIONNllLCAC
TURBOCHARGER ASSEMBLY CHECKl
Visually check the turbine wheel and the compressor wheelfor
cracking or other damage.
lCheck whether the turbine wheel and the compressor wheel
can be easily turned by hand.l
Check for oil leakage from the turbocharger assembly.l
Check whether or not the waste gate valve remains open.
If any problem is found, replace the part after disassembly.
OIL PIPE AND OIL-RETURN PIPE CHECK
Check the oil pipe and oil-return pipe for clogging, bending, or
other damage.
If there is clogging, clean it.
SERVICE POINTS OF INSTALLATIONNllLDAC-x_3SlNSTALLATlON OF OIL PlPE
Supply clean engine oil through the oil pipe installation hole
of the turbocharger assembly.
29. INSTALLATION OF TURBOCHARGER ASSEMBLY
Clean the alignment surfaces shown in the illustration.
Caution
When cleaning, care must be taken so that a piece of the
gasket does not enter the oil passage hole.

5. REMOVAL OF SNAP RING
Place the compressor cover assembly on the floor with its
end surface down and remove the snap ring with pliers.
CautionDuring removal, hold with a finger the snap ring which
can spring out.
O-ring
3EN2396. REMOVAL OF CARTRIDGE ASSEMBLY
Remove the cartridge assembly by tapping the compressor
cover with a soft hammer.
Caution
Some resistance will be experienced in the removal dueto the O-ring on the cartridge assembly.
INSPECTION;.rulim+A
TURBOCHARGER
1.Inspect the cast-iron turbine housing for damage, cracks, or
evidence of contact between the turbine blades and the
housing.
2.Manually open and close the waste gate valve to make sure
it operates freely.
3. Inspect the turbine and compressor wheels for wear,
damage, bent or broken blades.
4.Inspect the oil passage in the cartridge for signs of deposits
or blockage.
5. Clean the inlet section of the compressor cover with a rag.
Inspect it for signs of contact with the compressor turbine.
If worn, replace it.WASTE GATE ACTUATOR
1.Leak-test the waste gate valve actuator with a hand vacuum
pump.Replace the actuator if it does not hold vacuum.
2. Check the rod to see that it is not bent or binding.
SERVICE POINTS OF REASSEMBLYNllLHAB
7. INSTALLATION OF O-RING
Coat the inner surface of a new O-ring with a thin film of
engine oil, and set it in the groove of the cartridge assembly.
Caution
Be careful not to damage the O-ring while installing it as
oil leakage could result.

INSTALLATIQN OF CARTRIDGE ASSEMBLY
(I1 Coat the outer circumference of the cartridge assembly
O-ring with a thin film of engine oil.
(29 Install the cartridge assembly on the compressor cover
by aligning the dowel pin.
CautionWhen installing the cartridge assembly on the
compressor cover, be careful not to damage the
compressor wheel blades.5. INSTALLATION OF SNAP RING
Place the cartridge assembly with the compressor cover
faced down and install the snap ring.
CautionInstall the snap ring with the tapered side of its outside
diameter up.4. INSTALLATION OF TURBINE HOUSING
Install the compressor cover and cartridge assembly on the
turbine housing with the dowel pin in alignment.
Caution
1. Be careful not to damage the blades of the turbine
wheel.
2. Be careful to install the turbine housing in the correct
direction.
TEST OF WASTE GATE ACTUATOR OPERATIONNllLlAA
Using a tester, apply a pressure to the actuator and make surethat the
rod moves.Standard value:
M/T76.7
kPa (11.1 psi)
A/T72.0
kPa (10.4 psi)
CautionDo not apply a pressure of more than 85.3
kPa (12.4 psi) to
the actuator. Otherwise, diaphragm may be damaged.
Never attempt to adjust the waste gate valve.
