1.Clean the fuel injector
assembly (nozzle) and the cylinder head (fuel injector
insertion
hole) by following the procedure below. (1)
|
caution |
Do not clean the
injection part of the nozzle with a
resin spatula.
|
|
Using a resin spatula, scrape off the carbon deposit
on the fuel injector nozzle side
face ("A" shown in the figure). (2)
Spray carburettor cleaner (MZ100139) or equivalent to the
nozzle side face ("A" shown
in the figure). (3)
|
caution |
Do not touch the
injection part of the nozzle with
hand
or wipe it with a rag.
|
|
Leave the injection part for a while until the
carbon deposit melts down, and then blow
air to the injection part. (4)
Insert special tool ornament remover (MB990784) to the
cylinder head (fuel injector insertion
hole) with turning the special tool as shown, and scrape off
the carbon deposit. (5)
|
caution |
In order to
prevent carbon from adhering to the
inner surface
of the cylinder, blow air with the
piston in the TDC position.
|
|
Remove the special tool, and blow off the carbon
deposit on the cylinder head (fuel injector
insertion hole) by air. (6)
Check that there is no carbon deposit remaining on the
contact surface of the fuel
injector nozzle gasket.
|
note |
Repeat step 4 to
step 6 several times until the
carbon deposit is completely
removed.

2.Install the nozzle gasket,
fuel injector, pivot boss, and injector supporter to the
cylinder
head as shown in the figure. 3.Apply a small
amount of engine oil to the seat surface and thread of
injector holder
bolt, and then temporarily tighten the bolt to the cylinder
head. 4.Set the fuel leak-off gasket to the fuel
leakage pipe, and temporarily tighten to
the fuel injector and to the cylinder head using the eye
bolt. 5.Tighten the eye bolt of the fuel injector
side to the specified torque. Tightening
torque: 15 ± 2 N·m 6.Tighten
the eye bolt of the cylinder head side to the specified
torque. Tightening torque: 15 ± 2
N·m 7.Tighten the injector holder
bolt to the specified torque. Tightening
torque: 10 ± 1 N·m

8.
caution |
- When the tightening
angle is smaller than the specified
tightening angle, the appropriate
tightening capacity cannot
be secured.
- When the tightening angle is larger than
the specified tightening angle, remove
the bolt to start from the beginning
again according to the procedure.
|
Using special tool angle gauge (MB991614), tighten
the injector holder bolt in the illustrated
sequence by a further 120 to 125°.

|
1.Apply specified sealant to
portions indicated in illustration. Specified
sealant: ThreeBond 1217G or equivalent
note |
Install the semi-circular
packing immediately applying sealant.
|
2.
caution |
After the installation, until
a sufficient period of
time (one hour or more) elapses, do not apply
the oil or water to the sealant application area
or start the engine.
|
Install the semi-circular packing.
|

|
Using a proper socket wrench, the
oil seal is pressed and fit into the rocker cover.
|

|
Using a proper socket wrench, the
oil seal is pressed and fit into the rocker cover.
|
|
The stud should protrude 21 to 22
mm from the end of the rocker cover.
|

|
1.Apply specified sealant to
portions indicated in illustration. Specified
sealant: ThreeBond 1217G or equivalent
note |
Install the rocker cover
immediately applying sealant.

|
2.
caution |
Pay attention that the
connector does not damage the seal lip when
inserting
the rocker cover.
|
Slightly press the oil seal lip to the place in the
opposite direction of the connector,
shown in the illustration. 3.Leave enough
clearance for the connector to avoid touching the seal
lip.
|
![](../../../img/11/AK603150AB00ENG.png)
|
4.Slowly get the seal lip
through not making contact with the
connector. 5.Put the rocker cover down to the
installation location.
|
![](../../../img/11/AK603151AB00ENG.png)
|
6.Check that the
injector-sealing surface has the seal lip.
|

|
7.In accordance with the
tightening order shown in the illustration, tighten bolts to
2.5 ± 1.5
N·m. 8.
caution |
After the installation, until
a sufficient period of
time (one hour or more) elapses, do not apply
the oil or water to the sealant application area
or start the engine.
|
Again, in accordance with the tightening order shown
in the illustration, tighten bolts
to the specified torque of 10 ± 2 N·m.
