Disassembly and assembly

2. If a replacement electronic unit injector is installed,
the correct seven digit injector code that is located
in Position (A) must be programmed into the
electronic control module. Refer to
Troubleshooting, “Injector Code - Calibrate” for
more information.
Note: Record the seven digit injector code in Position
(A) before the electronic unit injector is installed.
3. Ensure that the fuel inlet port of the electronic unit
injector is capped. Ensure that the electronic unit
injector is clean.

4. If necessary, install studs (9) to the cylinder head.
Tighten the studs to a torque of 20 N·m (177 lb in)
5. If the original electronic unit injector (3) is to be
reused, remove the protective cap from the nozzle
and install a new sealing washer (10).
Note: Ensure that the nozzle for the electronic unit
injector is not damaged during installation of the new
sealing washer.
6. Remove the plug from the electronic unit injector
port in the cylinder head.
7. Ensure that the seat for the electronic unit injector
in the cylinder head is clean and free from
damage. Ensure that the sealing washer has been
removed from the cylinder head.
8. Position clamp (6) onto electronic unit injector (3).
Align the assembly of electronic unit injector (3) to
the bore for the electronic unit injector in the
cylinder head.
Note: Ensure that the clamp is correctly positioned
onto the electronic unit injector.
9. Push only on injector clamp (6) in order to install
electronic unit injector (3). Do not apply pressure
on any other part of the electronic unit injector.
Ensure that the electronic unit injector is pushed
firmly against the seat in the cylinder head.
10. Install washer (8) and nut (4) onto stud (9).
Tighten the nut finger tight.
Note: Ensure that the washer is correctly orientated.
11. Remove the plugs from the new fuel injection line.
Install the fuel injection line nuts hand tight. Refer
to Disassembly and Assembly, “Fuel Injection
Lines - Install” for the correct installation
procedure.
Note: Ensure that the ends of the fuel injection line
are seated into the electronic unit injector and the fuel
manifold.
Note: Do not torque the fuel injection line nuts
before the final torque has been applied to the
electronic unit injector clamp nuts (4).
12. When nuts (4) are installed, the nuts must be
tightened in two stages. Follow Step 12.a through
12.b for the correct torque sequence.
a. Tighten nuts (4) to an initial torque of 15 N·m
(133 lb in).
b. Tighten nuts (4) to a final torque of 25 N·m
(221 lb in).
13. If necessary, repeat Step 1 through Step 12.b in
order to install the remaining electronic unit
injectors.
14. Tighten the fuel injection line nuts to a torque of
25 N·m (221 lb in). Refer to Disassembly and
Assembly, “Fuel Injection Lines - Install” for further
information.
