| 1. |
Turn the ignition switch
OFF. |
| 2. |
Disconnect the injector
connector. |
| 3. |
Measure resistance between the injector
terminals 1 and 2. |
| 4. |
Check that the resistance is within the
specification.
Specification:
Refer to
“Specification”

In case of removing the high pressure fuel
pump, high pressure fuel pipe, delivery pipe, and injector, there
may be injury caused by leakage of the high pressure fuel. So don’t
do any repair work right after engine stops.
|
| 1. |
Turn the ignition switch OFF and disconnect
the battery negative (-) cable. |
| 2. |
Release the residual pressure in fuel
line.
(Refer to Fuel Delivery System - “Release
Residual Pressure in Fuel Line”)
|
When removing the fuel pump relay, a
Diagnostic Trouble Code (DTC) may occur. Delete the code with
the GDS after completion of “Release Residual Pressure in Fuel
Line”
work. | |
| 3. |
Remove the delivery pipe & injector
assembly (Refer to "Delivery Pipe" in this
group). |
| 4. |
Remove the connector (A) and the fixing clip
(B), and then separate the injector from the delivery
pipe.
|
| •
|
Do not reuse the used injector fixing
clip. | |
| •
|
Install the component with the specified
torques. |
| •
|
Note that internal damage may occur when
the component is dropped. If the component has been dropped,
inspect before
installing. | |
| •
|
Apply engine oil to the injector
O-ring. |
| •
|
Do not reuse the used injector
O-ring. | |
| •
|
Do not reuse the used
bolt. | |
| •
|
When inserting the injector, be careful
not to damage the injector
tip. | |
| •
|
Do not reuse the support
disc. |
| •
|
Do not reuse the injector rubber
washer. |
| •
|
When replacing the rubber washer, the
steal plate (A) part should be faced the cylinder installation
part and the rubber plate (B) part should be faced the
injector body part.
| |
| •
|
Do not reuse the combustion
seal.
| |
| 1. |
Installation is reverse of
removal. |
The injector combustion
seal should be replaced new one to prevent leakage after removing the
injector.
| 1. |
Remove the combustion seal (A) with a wire
cutter.
|
Grip the sealing ring carefully, pull it
to form a small loop and then cut it.
Be careful not to damage the surface of
the valve sleeve with the wire
cutter. | |
| 2. |
Before the assembly of the sealing ring the
groove must be cleaned using a clean cloth.
Any coking of the injector sealing surface
must be carefully removed with a brass-wire brush.
|
The surfaces of the new sealing ring
must be clean and free of
grease. | |
| 3. |
Place the seal installing guide (B) (SST No.:
09353-2B000) on the tip of the injector not to damage the injector
tip (A).
Push the sealing ring (C) with thumb and index
finger over the conical assembly tool until it snaps into the
groove.
The complete assembly must not take longer
than 2 to 3 seconds.
|
| 4. |
To size the sealing ring the injector is first
introduced into the sizing tool (A) (SST No.: 09353-2B000) and then
pressed and at the same time rotated 180° into the sizing
tool.
|
| 5. |
Pull the injector out of the sizing tool by
turning it in the reverse direction to that used for the press-in
process.
|
Check that the seal ring has not been
damaged during assembly to the injector and that no
circumferential scratches are present.
Do not reuse the combustion
seal.
The seal must be completely free of
grease and
oil. | |
| 6. |
Check the combustion seal (A)
installation.
