Note: Do not remove the quill tube. This action will reduce the risk of contamination to the
system.
1. Fully loosen quill tube nut (1) . Pull quill tube (1) out of the bore until you see O-ring seal
(2) . This action will ensure that the injector does not contact the quill tube during removal.
At this time, inspect O-ring seal (2) for wear or for damage. Replace the O-ring seal if
necessary.

Typical Example
3. Remove bolt (5) from clamp (6) .
Note: When possible, remove the unit injector by hand by twisting the unit injector and
pulling upward. Be sure not to strike the unit injector during the removal procedure.
4. If unit injector (4) cannot be removed by hand, go to Step 5.

Typical Example
Note: Do not damage the unit injector during removal. Side loading may damage to the unit
injector.
5. Position Tooling (A) under unit injector clamp (6) . Carefully remove unit injector (4) from
the cylinder head.
Installation Procedure
NOTICE
Keep all parts clean from contaminants.
Contaminants may cause rapid wear and shortened component life.
1. Evacuate as much fuel and oil as possible from the cylinder head before installing the unit
injector. Several evacuations may be necessary. Use Tooling (C) to remove the fuel and oil
from the cylinder.

2020/6/7

Note: Tooling (F) is available to clean loose material from the sleeve bore and the cylinder.
2. Clean the carbon from the sleeve, the sleeve bore, and the end of the unit injector. Clean the
carbon from the seat area that is inside of the cylinder head. A fine grade of Tooling (B) is
preferred. Clean the carbon from the cylinder head. If the sleeve of the unit injector has been
removed, use Tooling (D) to remove only carbon from the surface of the sleeve. If the
sleeve of the unit injector is installed, use Tooling (E) to clean the carbon deposit from the
inside of the sleeve.
The following procedure is the preferred method of cleaning the sleeve bore.
Place a 38 mm (1.5 inch) square piece of Scotch Brite material on the end of Tooling (F) .
Twist Tooling (F) with Tooling (H) against the lower surface of the sleeve bore.
The surface should be cleaned until the surface is smooth and shiny. The entire sleeve bore
should be cleaned in order to remove any loose carbon particles.
Note: Tooling (G) is available to clean loose material from the sleeve bore and the cylinder.
NOTICE
The correct procedures and tooling specifications must always be used.
Failure to follow any of the procedures may result in damage,
malfunction, or possible engine failure.
Note: Replace the O-ring seals on the injector.
3. Install O-ring seal (9) and O-ring seal (10) on unit injector (4) . Lubricate O-ring seal (9) , O
-ring seal (10) , and the sleeve bore of the unit injector sparingly with clean engine oil.
4. Record the serial number for the injector and the injector confirmation code. When you
install a new unit injector, the E-Trim value must be programmed into the Engine Control
Module. For more information, refer to Troubleshooting, "Injector Trim File - Install".

2020/6/7

Note: Verify quill tube (1) is positioned out of the bore enough to see O-ring seal (2) . This
action will ensure that the injector does not contact the quill tube during installation.
5. Place unit injector (4) into the bore. Make sure that the key (7) for the unit injector fits into
slot (8) in the cylinder head.
6/9(W)
w
2020/6/7

Note: Use new socket head bolt (5) .
6. Position unit injector clamp (6) with the label "C9" in the up position. Install socket head
bolt (5) into unit injector clamp (6) . Tighten socket head bolt (5) to a torque of 28 ± 3 N·m
(21 ± 2 lb ft) in order to secure unit injector (4) .
7. Connect harness assembly (3) to the unit injector.
7/9(W)
w
2020/6/7

Note: Check the O-ring seal for wear or for damage. If necessary, replace the O-ring seal.
8. If the O-ring seal was damaged, perform Step 8.a and Step 8.b.
8/9(W)
w
2020/6/7

a. Inspect the Sealing Surface (A) for damage. Replace quill tube (1) if damage was
found.
b. Lubricate new O-ring seal (2) with clean engine oil. Install new O-ring seal (2) .
9. Lubricate the O-ring seal, the nut face, and the threads with clean engine oil. Insert quill
tube (1) into the bore with the ball on the right side. Once the quill tube has bottomed out,
rotate the quill tube until the ball engages with the slot. The quill tube should drop slightly
when the ball is engaged with the slot. This action will install quill tube (1) . Ensure that the
ball is in alignment with the slot for quill tube (1) . Tighten the nut for quill tube (1) to a
torque of 70 ± 3 N·m (52 ± 2 lb ft).
End By:
a. Install Compression Brake (If Equipped).
b. Install the valve mechanism cover.
c. Install the fuel injection line.
