Information:
ACTION REQUIRED
Take the following actions after a failure occurs on one or more injectors in any of the engines in the Affected Product. A failure is considered extreme fuel dilution, in the range of 20 liters per minute.
- If one or more injectors fail it may be necessary to replace additional injectors at the time of repair.
- Verify the injector serial number of the failed injector. Verify the injector serial number of the remaining injectors in the engine. Refer to Image1 for an example of part number (A) and injector serial number identification (B). If the injector serial number falls within the range of 1134640-1234085, the injector should be replaced. The 154-6389 Buttons on the engine should also be replaced. The 154-6389 Button and 9F-7707 Retaining Clip on the injector rocker arms should also be replaced.
Only injectors falling within the range of 1134640-1234085 should be replaced and claimed under this program.
Refer to the Disassembly and Assembly manual for the removal/installation procedure of the unit injector and button.
Excessive fuel dilution of the engine oil requires changing the engine oil and filters. Refer to the appropriate Service Manual as necessary.
