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.

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.

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.

DISASSEMBLY SERVICE POINTS
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.

COMPRESSOR COVER
Check the compressor cover for traces of contact with the
compressor wheel and other damage.
TURBINE WHEEL ASSEMBLY
1. Check the turbine and compressor wheel blades for bend,
burr, damage, corrosion and traces of contact on the
back side and replace if defective.
2. Check the oil passage of the turbine wheel assembly
for deposit and clogging.
3. In the case of water cooled type, check also the water
passage for deposit and clogging.
