ACTION REQUIRED
1. Refer to Special Instruction, REHS5023, "Replacing the Fuel Injection Pump on Certain C9.3 Engines". Replace the existing 375-5244 or early production 379-0150 common rail fuel injection pump with the new production 379-0150 common rail fuel injection pump and new gasket 6V-8260. Install a new 356-5214 fuel line from the common rail fuel injection pump to the fuel rail.
2. Refer to C9.3 Disassembly and Assembly, KENR8149 "Engines for Caterpillar Built Machines". Replace the prior 362-0770 Pressure Relief Valve with 415-4991 Pressure Relief Valve, and 228-7102 O-ring.
3. Refer to Service Magazine, SEPD1818, "An Improved Fuel Injection Pump Group Is Used on Certain C9.3 Machine Engines", in order to record the common rail fuel injection pump serial number. This serial number must be entered into the containment service letter claim story.
