Removal guidelines
 
A


Removal of the delivery pipe, the injector and the fuel
pressure regulator ASSY
Remove the deliver pipe, with the injector and the fuel pressure
regulator intact.
Caution
When removing the delivery pipe, be careful not to drop the
injector.
Fitting guidelines



A 

Connecting the O-ring and the fuel high pressure hose
1. Apply a small quantity of fresh engine oil to the O-ring, and
insert it into the delivery pipe without damaging the O-ring.
2. Check that the high pressure hose can be turned smoothly. If it
cannot be turned smoothly there is a possibility that it is biting
into the O-ring, so remove the high pressure hose and check for
any damage to the O-ring. If the O-ring is undamaged, reinsert it
into the delivery pipe and check once more whether the hose
can be turned smoothly.
3. Tighten the mounting bolt to the specified torque.
Tightening torque: 5.0 ± 1.0 N·m

Removal guidelines
 
A


Removing the O
2sensor
After removing the O
2sensor connector and the clamp, use the
special O
2 sensor wrench (MD998770) to remove the O
2sensor.
 
B


Removing the oil feed pipe
Caution
After removing the oil feed pipe, ensure that there is no foreign
matter in the oil access hole on the turbocharger.
Fitting guidelines



A 
Fitting the turbocharger ASSY
1. Clean away any grease clogging the connection between the oil
pipe and the water pipe, and any grease clogging the eyebolts
and the inside of the pipes.
2. If there is any carbon in the oil access on the turbocharger
ASSY, clean it or blow it away.
Caution
Ensure that no foreign matter gets inside the turbocharger
ASSY.
