LEAKAGE PIPE/EYE BOLT INSTALLATION
1. Clean the fuel injector assembly (nozzle) and the

cylinder head (fuel injector insertion hole) by
following the procedure below.

CAUTION

Do not clean the injection part of the nozzle with
a resin spatula.

(1) Using a resin spatula, scrape off the carbon

deposit on the fuel injector nozzle side face
("A" shown in the figure).

(2) Spray the carburetor cleaner (MZ100139) or

equivalent to the nozzle side face ("A" shown
in the figure).

CAUTION

Do not touch the injection part of the nozzle with
hand or wipe it with a rag.

(3) 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.

CAUTION

In order to prevent carbon from adhering to the
inner surface of the cylinder, blow air with the
piston in the TDC position.

(5) 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

CAUTION

• If the bolt is tightened less than the specified

lower limit of 120

°, the bolt may become

loose. Be sure to tighten correctly.

• If the bolt is tightened in excess of the speci-

fied upper limit of 125

°, loosen the nut com-

pletely and repeat the entire procedures.

8. Using special tool angle gauge (MB991614),

tighten the injector holder bolt in the illustrated
sequence by a further 120

° to 125°.

>>B<< SEMI-CIRCULAR PACKING
INSTALLATION

Apply specified sealant to portions indicated in illus-
tration.

Specified sealant: Three bond 1217G or
equivalent

illustration.

Specified sealant: Three bond 1217G or
equivalent

NOTE: Install the rocker cover assembly immedi-
ately after applying sealant.
2. Install the rocker cover assembly to the cylinder

head.

3. Tighten the rocker cover assembly mounting bolts

to the specified torque in the order shown in the
figure.

Tightening torque: 3.0

± 1.0 N⋅m

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.
4. Tighten the rocker cover assembly mounting bolts

to the specified torque in the order shown in the
figure again.

Tightening torque: 10

± 2 N⋅m

REMOVAL AND INSTALLATION

M1133009600389

CAUTION

• The reinstallation histories of the removed fuel injection pipe and fuel supply pump pipe are up to

five times. To count how many times the fuel injection pipe and fuel supply pump pipe are rein-
stalled, record the number of the reinstallation histories on the service booklet by adding this lat-
est number of the histories, which is usually "1", to the previous one. Use a new fuel injection pipe
or fuel supply pump pipe when the total reinstallation history numbers reach five times, or when
the fuel injector assembly, common rail assembly or supply pump assembly is replaced. In this
case, record " a new fuel injection pipe or fuel supply pump pipe, the number of the reinstallation
histories is zero" on the service booklet.

• If a fuel leak is present in the fuel injection pipe and fuel supply pump pipe once, do not reuse it

and replace with a new one.

• If the fuel injector assembly, common rail assembly or supply pump assembly is replaced, the

contact surface (seal surface) between the fuel injection pipe and fuel supply pump pipe, and the
other side component is changed, do not reuse the fuel injection pipe and fuel supply pump pipe
and replace with a new one.

• When the injection pipe is reinstalled, confirm there is no foreign material on the seal surface or in

the pipe and then install it not to deviate from the axis, fitting the seal surface.
