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

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.

Removal guidelines
 
A



Removing the delivery pipe, the injector, and the fuel
pressure regulator ASSY
Loosen the bolts holding it in place, slightly dislodge all of the
components and make space for the alternator to be removed.
 
B


Removing the drive belt
The following procedures are necessary because a serpentine drive
system with auto-tensioner has been installed.
1. Insert a 12.7sq spinner handle into the auto-tensioner hole, and
turn the auto-tensioner in an anti-clockwise direction until it
reaches the stopper.
2. Align the A hole and the B hole, hold them in place by inserting
an L-shaped hexagonal Allen Key, and remove the drive belt.
Caution
If planning to re-use the drive belt, ensure that it will be
refitted the same way round, by marking the back of the belt
with chalk arrows indicating the direction of movement.
 
C


Removing the alternator
Push the whole engine up using a garage jack, and remove the
alternator from above.
