PROBLEM
The fuel inlet check valves, on the fuel injection pump, may fail on certain C6.6 Industrial Engines that are installed in specific OEM Applications. A failure of the inlet check valves could result in any of the following symptoms: failure to start, prevention of the engine from achieving full power, or a de-rate of the engine.
Before any repair is carried out, ensure the appropriate trouble shooting steps have been followed and carried out.

In order to allow equitable parts availability to all participating dealers, please limit your initial parts order to not exceed 32% of dealership population. This is an initial order recommendation only, and the ultimate responsibility for ordering the total number of parts needed to satisfy the program lies with the dealer.
ACTION REQUIRED
Replace the existing fuel injection pump group with a new 349-5736 fuel injection pump group.
Refer to appropriate service manuals as necessary.
Rework Procedure:
1. Remove machine parts as necessary to gain sufficient access to the engine.
2. Remove existing fuel injection pump and replace it with a new 349-5736 fuel injection pump group. Refer to the Disassembly & Assembly Instruction RENR9722 Fuel Injection Pump - Remove and Install.
3. Ensure that all the warnings and notices are adhered to and safety practices are followed. Ensure that the protection caps are used during this operation to prevent issues with contamination.
4. Install all parts that were removed to gain access to the engine.
5. Check for leaks and repair as necessary.
