• Wait until the fuel temperature drops before carrying out any work.
• Order the special high pressure injection circuit plug kit.
• It is forbidden to open an fuel injector. If you open an fuel injector by mistake, you will have to
change it.
NOTE:
It is possible to replace a single injection tube.
1.
Remove the battery. Refer to

.
3.
Remove fuel return hose.
• Move without removing the fuel return hose clip using a flat
bade screwdriver.
4.
Disconnect and remove fuel hose.
5.
Remove fuel collector and injection tube (center).
6.
Remove injection tube (No. 1, 2, 3, 4).
7.

CAUTION:
• Handle fuel injector carefully without giving an impact.
• Never disassemble fuel injector.
8.
Remove injection rail and injection rail protector seal.
CAUTION:
In case of fuel rail pressure sensor fitted with a color ring:
• replacing the sensor is forbidden
• the injector rail must be completely replaced if the fuel rail pressure sensor fails.
9.
Plug all the holes in the injection circuit. Refer to
EM-289, "Precaution for Diesel Equipment"
INSTALLATION
1.
If an injector is replaced, not the IMA code and the corresponding cylinder number and perform “injector
adjustment value registration”. Refer to
.
2.
