Emissions Recall
Subject: Fuel Injector Inspection
Date: 03-03-2009
Bulletin: R0034
Campaign #: A6260_A6270
Affected Models: 2008-2009 NA6J (145), NB6J (165), NC6J (185), ND8J (238), NE8J (268),
NJ8J (268A), NV8J (338)

NOTE: When scheduling a vehicle for this Emission Recall, instruct the customer to
completely fill the fuel tank(s) prior to delivery to the Dealer. No claims for fuel will be
accepted as part of this Recall.
Description:
This bulletin includes the instructions to complete the following.
1. Determine the condition of the fuel injectors by monitoring quantity value using Hino
Diagnostic Explorer.
2. If the fuel injector condition is determined to be “Acceptable” Diesel Cleaner will be added to
the fuel without replacing the fuel injectors.
3. If the fuel injector condition is determined to be “Unacceptable” the fuel injectors will be
replaced without adding the Diesel Cleaner.
Subject Vehicles:
2008 and 2009 model year NA6J (145), NB6J (165), NC6J (185), ND8J (238), NE8J (268), NJ8J
(268A), and NV8J (338) Hino conventional trucks assembled at the Long Beach, CA. and
Williamstown, WV assembly plants.

Condition:
Abnormal noise and vibration within the engine occurs due to the impeded operation of the
injector needle which is caused by the formation of deposits in the fuel.
The deposit formation occurs when metallic compounds, which are a part of the synthetic rubber
hose material, are extracted from the synthetic rubber by naturally occurring solvents in the fuel
and then exposed to abnormally high fuel temperature. The abnormally high fuel temperature is
created when excessive air enters the fuel stream from the fuel filter and is compressed by the
supply pump. This deposit accumulates on the fuel injector needle and impedes the needle
movement which causes abnormal post injection timing to occur. The abnormal post injection
timing causes the abnormal noise and vibration of the engine.

Emissions Recall
Important: Verify on the Hino DCS Warranty System that the vehicle still needs to have
this work performed.

Before You Begin:
Read and understand all instructions and procedures before you begin. Read and observe all
Caution and Warning safety alerts that precede these instructions while following these
procedures. The alerts help to avoid damage to components, serious personal injury, or both.

Once Recall is completed
Fill out the Recall Completion sticker as shown
in the picture to the left. This sticker should be
attached to the left door jam above the V.I.N.
decal.

!!! WARNING !!!
Park the vehicle on a flat and level surface.
Apply the parking brake and confirm parking brake activation.
Shift transmission to NEUTRAL.
Block the wheels to prevent the vehicle from moving.
Use care when working around surfaces which may be hot.
Wear safety glasses to prevent eye injuries.
Properly calibrated torque wrenches must be used to prevent possible ensuing
damage.
Refer to any applicable Material Safety Data Sheet (M.S.D.S.) for additional
information.

Inspection Procedure:
1. Start the engine.
2. Turn off the exhaust brake switch.
3. Connect to Hino Diagnostic Explorer.
4. Once communicating with ECU

Select “Check Function”
Select “Activation Test”

Set “Target Engine Speed” to 1500 RPM
Select “Start” to bring engine to
selected rpm.

5. Select Data Monitor function to view the following data channels:
A) Engine speed;
B) Engine coolant temperature;
C) Injection quantity value.

6. When the engine coolant temperature reaches 176F (80C), record the injection quantity
value.
Determine if the injection quantity value is acceptable or unacceptable by comparing the
recorded injection quantity value to the following chart.
NOTE: To obtain a valid injection quantity value this step must be performed while the
exhaust brake is “OFF”. When certain conditions are present the ECU may turn the
exhaust brake “ON”. Make sure that during this procedure the exhaust brake lamp on
the instrument panel remains “OFF”. If the exhaust brake lamp turns “ON”, allow the
engine to idle until the lamp turns “OFF” and then record the injection quantity value.

7. If the injection quantity value is ACCEPTABLE, proceed to the “Fuel System Cleaning”
section below. If the injection quantity value is UNACCEPTABLE, proceed to the
“Injector Replacement” section below the Fuel System Cleaning section.
8. The injection quantity value must be included in the warranty application.
Fuel System Cleaning:
1. Determine the amount of Diesel Fuel Injector Cleaner required based on the chart below.
If the vehicle is equipped with dual fuel tanks the fuel gauge in the instrument cluster
represents the fuel level in both fuel tanks. The Diesel Cleaner must be added to both
fuel tanks.
Example:
Fuel tank capacity = 50 gallons
Fuel level = ¼ full
Diesel Fuel Injector Cleaner required = 1 bottle

WARNING: Never add more Diesel Fuel Injector Cleaner than the amount specified. Use
of excessive Diesel Fuel Injector Cleaner will damage the fuel system.
2. Add the required amount of Diesel Fuel Injector Cleaner into the fuel tank(s).
3. Instruct the customer to operate the vehicle a minimum of one hour before refueling. This
will maintain the proper concentration of Diesel Fuel Injector Cleaner to clean the fuel
injectors properly.
4. No further action is required.

Note: Perform these steps to each injector assembly.

1. Disconnect the injector harness from the
sub-harness assembly.

2. Remove the injector harness and
bracket assembly.

3. Carefully raise the injector harness
bracket off of the studs and lay it on the
left side of the cylinder head.
This will allow full access to the injectors
and surrounding area.

4. Carefully remove the leakage pipe and
its bolts.
Leakage pipe bolts per engine model:
J05 = 5 bolts
J08 = 7 bolts

5. Remove all fuel injector pipe clamps
securing the pipes.
CAUTION: Cover the open ends of the fuel
injector pipes to prevent dirt from entering
the fuel system.

6. Loosen the flare nuts at BOTH ENDS of
each fuel injector pipe. Remove the
injector pipes.

CAUTION: Use care during removal and do not damage the fuel injector pipe seal.

7. Remove the two bolts (6cyl. only) from
the fuel injector pipe seal and then
gently pry outward between the steel
ring of the fuel injector pipe seal and the
