INSTALLATION
CAUTION:
Do not reuse O-rings.
1.
Install seal ring to fuel injector as per the following:
CAUTION:
• Handle seal ring with bare hands. Never wear gloves.
• Never apply engine oil to seal ring.
• Never clean seal ring with solvent.
a.
Install an injector seal drift set [SST: KV101197S0 (—)] (A) to
fuel injector (1).
b.
Set seal ring (1) to injector seal drift set [SST: KV101197S0 (—)]
(A).
c.
Straightly insert seal ring (1), which is set in step 2, to fuel injec-
tor as shown in the figure and install.
CAUTION:
Be careful that seal ring does not exceed the groove portion
of fuel injector.
d.
Insert injector seal drift set [SST: KV101197S0 (—)] (A) to injec-
tor and rotate clockwise and counterclockwise by 90
°
while
pressing seal ring to fit it.
NOTE:
Compress seal ring, because this operation is for rectifying
stretch of seal ring caused by installation and for preventing
sticking when inserting injector into cylinder head.
2.
Install O-ring and backup ring to fuel injector. When handing new O-ring and backup ring, paying attention
to the following caution items:

• Do not reuse O-ring.
• Handle O-ring with bare hands. Never wear gloves.
• Lubricate O-ring with new engine oil.
• Never clean O-ring with solvent.
• Check that O-ring and its mating part are free of foreign material.
• When installing O-ring, be careful not to scratch it with tool or fingernails. Also be careful not to
twist or stretch O-ring. If O-ring was stretched while it was being attached, never insert it quickly
into fuel tube.
• Insert new O-ring straight into fuel rail. Never decenter or twist it.
• Always install the back up ring (1) in the right direction as
instructed.
3.
Install fuel injector (1) to fuel rail (2) as per the following:
a.
Install fuel injector holder (5) to fuel injector.
CAUTION:
• Never reuse fuel injector holder. Replace it with a new
one.
• Be careful to keep fuel injector holder from interfering
with O-ring. If interference occurs, replace O-ring.
b.
Insert fuel injector into fuel rail with fuel injector holder attached.
• Insert it while matching it to the axial center.
• Insert so that protrusion (A) of fuel injector is aligned to cutout
(B).
c.
Check that installation is complete by checking that fuel injector
does not rotate or come off.
• Check that protrusions of fuel injectors and fuel rail are aligned
with cutouts of clips after installation.
4.
Install fuel rail and fuel injector assembly to cylinder head.
• Tighten mounting bolts and nuts in two steps in numerical
order as shown in the figure.
5.
Connect injector harness connector.
6.
Install fuel pressure sensor, if removed.

INSPECTION AFTER INSTALLATION
Check on Fuel Leakage
1.
Turn ignition switch “ON” (with the engine stopped). With fuel pressure applied to fuel piping, check there
are no fuel leakage at connection points.
NOTE:
Use mirrors for checking at points out of clear sight.
2.
Start the engine. With engine speed increased, check again that there are no fuel leakage at connection
points.
CAUTION:
Never touch the engine immediately after stopped, as the engine becomes extremely hot.

INSPECTION AFTER INSTALLATION
Inspection for Leakage
The following are procedures for checking fluids leakage, lubricates leakage, and exhaust gases leakage.
• Before starting engine, check oil/fluid levels including engine coolant and engine oil. If less than required
quantity, fill to the specified level. Refer to
MA-10, "Fluids and Lubricants"
.
• Use procedure below to check for fuel leakage.
- Turn ignition switch “ON” (with engine stopped). With fuel pressure applied to fuel piping, check for fuel leak-
age at connection points.
- Start engine. With engine speed increased, check again for fuel leakage at connection points.
• Run engine to check for unusual noise and vibration.
• Warm up engine thoroughly to check there is no leakage of fuel, exhaust gases, or any oil/fluids including
engine oil and engine coolant.
• Bleed air from lines and hoses of applicable lines, such as in cooling system.
• After cooling down engine, again check oil/fluid levels including engine oil and engine coolant. Refill to the
specified level, if necessary.
