REMOVAL SERVICE POINTS
AA"DELIVERY PIPE, INJECTOR AND FUEL
PRESSURE REGULATOR ASSEMBLY REMOVAL
The delivery pipe must be removed with the injector and
fuel pressure regulator attached.
Caution
Take care not to drop delivery pipe, injector, or fuel
pressure regulator assembly when removing those parts.

INTAKE AND EXHAUST -Intake Manifold15-18
INSTALLATION SERVICE POINTS
"AAFUEL HIGH-PRESSURE HOSE CONNECTION
1. Apply a drop of new engine oil to the O-ring.
Caution
Be sure not to let engine oil enter the delivery pipe.
2. While turning the injector, high-pressure fuel hose and
fuel pressure regulator to the right and left, install the
delivery pipe, while being careful not to damage the O-ring.
After installing, check that the hose turns smoothly.
3. If it does not turn smoothly, the O-ring may be trapped,
remove the injector, high-pressure fuel hose or fuel
pressure regulator and then re-insert it into the delivery
pipe and check once again.
4. Tighten the high-pressure fuel hose to the specified torque.
Tightening torque: 5.0±1.0 N⋅m
INSPECTION
Check the following points; replace the part if a problem is
found.
INTAKE MANIFOLD CHECK
1. Check for damage or cracking of any part.
2. Check for obstruction of the negative pressure (vacuum)
outlet port, and for obstruction of the water passage or
gas passage.
3. Using a straight edge and thickness gauge, check for
distortion of the cylinder head installation surface.

REMOVAL SERVICE POINT
AA"OXYGEN SENSOR REMOVAL
Use special tool to remove the oxygen sensor.
AB"OIL FEED PIPE REMOVAL
Take care not to let foreign objects get into the oil passage
hole of the turbocharger after the oil feed pipe is removed.
INSTALLATION SERVICE POINT
"AATURBOCHARGER INSTALLATION
1. Clean the oil feed pipe, oil return pipe, water pipe fitting,
the inside of eye bolt, and individual pipe for clogs.
2. Clean or blow the air if carbon particles are stuck to the
oil passage of the turbocharger.
Caution
Take care not to let foreign objects get into the
turbocharger.
3. Refill new engine oil at the oil feed pipe fitting hole of
the turbocharger.

Install the gasket so that its print part can face towards the
oil pan side.
INSPECTION
Check the following points; replace the part if a problem is
found.
1. EXHAUST MANIFOLD CHECK
(1) Check for damage or cracking of any part.
(2) Using a straight edge and a feeler gauge, check for
distortion of the cylinder head installation surface.
Standard value: 0.15 mm or less
Limit: 0.20 mm
2. TURBOCHARGER ASSEMBLY CHECK
(1) Visually check the turbine wheel and the compressor
wheel for cracking or other damage.
(2) Check whether the turbine wheel and the compressor
wheel can be easily turned by hand.
(3) Check for oil leakage from the turbocharger assembly.
(4) Check whether or not the waste gate valve remains open.
If any problem is found, replace the part after disassembly.

AA"SNAP RING REMOVAL
Lay the unit with the compressor cover side facing down
and using snap ring pliers, remove the compressor cover
attaching snap ring.
Caution
When removing the snap ring, hold it with fingers to
prevent it from springing away.
AB"TURBINE WHEEL ASSEMBLY REMOVAL
Remove the turbine wheel assembly, striking the
circumference of the compressor cover with a plastic hammer.
The turbine wheel assembly may be a little hard to remove
due to an O-ring put on the outer circumference.
CLEANING
1. Use a clean cleaning oil commercially available. Do not
use corrosive cleaning oils as they could damage to some
parts.
2. Use a plastic scraper or hard brush to clean aluminum
parts.
REASSEMBLY SERVICE POINTS
"AAO-RING INSTALLATION
Apply a light coat of engine oil to a new O-ring and fit in
the turbine wheel assembly groove.
Caution
When installing the O-ring, use care not to damage it. A
damaged O-ring causes oil leaks.
"BATURBINE WHEEL ASSEMBLY
1. Apply a light coat of engine oil to the periphery of the
O-ring.
2. Install the turbine wheel assembly to the compressor cover
in relation to the dowel pin.
Caution
Use care not to damage the blades of turbine wheel
and compressor wheel.

"DATURBINE HOUSING INSTALLATION
Install the turbine housing in relation to the dowel pin.
Caution
Use care not to damage the blades of turbine wheel.
"EACOUPLING INSTALLATION
Install the coupling and tighten to the specified torque.
"FAWASTE GATE ACTUATOR OPERATION CHECK
Using a tester, apply a pressure of approx. 100.0 kPa to
the actuator and make sure that the rod moves.
Caution
Do not apply a pressure of more than 113.3 kPa to the
actuator. Otherwise, diaphragm may be damaged. Never
attempt to adjust the waste gate valve.
INSPECTION
TURBINE HOUSING
1. Check the housing for traces of contact with the turbine
wheel, cracks due to overheating, pitching, deformation
and other damage. Replace with a new turbine housing
if cracked.
2. Operate the waste gate valve lever manually to check
that the gate can be operated and closed smoothly.
