ACTION REQUIRED

Show/hide table

Take the following actions after a failure occurs on one or more injectors in any of the machines listed in this service letter.

- If one or more injectors fail it may be necessary to replace up to 6 injectors at the time of repair.

NOTE: There will be situations when all 6 injectors do not have to be replaced. Refer to next paragraph to determine which injectors should be replaced.

- If an injector repair has previously been performed after approximately 01Oct07 on any of the listed machines, only the injectors that were not replaced at that time should be replaced as part of this program. This should further be verified by comparing the injector serial numbers in the engine to a range of 3B115776403B to 3B11676551F9. Disregard the first and last two characters in the serial number (in this case "3B" and "3B" in the first serial number and "3B" and "F9" in the second serial number). The reason for verifying the serial number range is due to a batch change of the internal part that is failing. The change was made after serial number 3B11676551F9.

NOTE: Only injectors falling within the range of 11577640-11676551 should be replaced and claimed under this program.

- If the suspect injector can not be identified by using the automatic cylinder cutout test use the two methods below.

- First, run a manual cylinder cutout test at a high engine speed with some load on the engine. When the injector that has failed is cutout, the sound of the engine should be more normal as opposed to the loud knocking heard when the failed injector is active. The second method is to unplug the wiring harness at the valve cover base that sends current to the injector solenoids as well as the harness connection for the injection actuation pressure sensor. By making these disconnections, the fuel injectors will not fire and the HEUI pump will go to maximum actuation pressure. Then remove the valve cover and crank the engine. The injectors that have failed should expel more oil (from the HEUI System) than those that are not failed.

-Refer to RENR9579 for removal/install procedure of the unit injector.

-The serial number of all injectors replaced in a machine covered under this service letter must be documented in the claims story.
