ACTION REQUIRED
Show/hide table
Take the following actions only after a failure occurs on one or more injectors in any of the engines listed in the Affected Product. A failure is considered extreme fuel dilution of the engine oil, 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 Button and 9F-7707 Retaining Clip on the injector rocker arms should also be replaced. NOTE: 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 removal/installation procedure of the unit injector and button. Excessive fuel dilution of the oil requires changing the engine oil and oil filters. Refer to appropriate Service Manual as required. NOTE: For Marine engines installed on a twin-engine vessel: it is accepatble to apply this service letter Before Failure and replace the injectors of the sister engine, assuming the engine serial number is included in this program and the injector serial numbers are within the range outlined above. |
