- Engines:
- 3054 (S/N: 2PW1-UP; 4ZK1-UP; 5YS1-UP; 6FK1-UP)
- 3054B (S/N: 5MF1-UP)
Description of Change: A new fuel transfer pump has been introduced for use on 3054 and 3054B engines. The new one-piece fuel transfer pump must not be disassembled. A strainer is installed on the inlet side of the fuel transfer pump. The strainer must be cleaned after every 500 hours or after every 12 months. The removal procedures and the installation procedures that are used on the new fuel transfer pumps are identical to the procedures that are used on previous fuel transfer pumps.
The new fuel transfer pump comes as a kit. The kit includes the gasket for mounting the fuel transfer pump to the engine. The 121-3221 Gasket that is used on the new fuel transfer pump is identical to the gasket that is used on previous fuel transfer pumps. A 201-0878 Filter Kit is installed on the inlet side of the new fuel transfer pump.
Adaptable To: The new 201-0877 Fuel Transfer Pump is a direct replacement for the former 121-3220 Fuel Priming Pump Gp. The new fuel transfer pump is adaptable to 3054 (S/N: 2PW1-UP; 4ZK1-UP; 5YS1-UP; 6FK1-UP) engines and 3054B (S/N: 5MF1-UP) engines.
Procedure to clean the fuel filter
- Turn off the fuel supply to the engine.
- Loosen the fuel line nut that holds the fuel inlet line to the fuel transfer pump and remove the inlet fuel line.
- Loosen and remove the hexagonal fuel inlet connection at the inlet of the fuel transfer pump.
- Remove the filter and the O-ring seal from the fuel inlet connection.
- Clean the fuel filter with clean diesel fuel. Dry the fuel filter with low pressure compressed air. A 201-0878 Filter Kit is available for the new fuel transfer pump. The filter kit includes a new filter and a new O-ring seal.
- Install the filter into the fuel inlet connection and install the new O-ring seal, if necessary.
- Install the hexagonal fuel inlet connection into the fuel transfer pump. Tighten the hexagonal fuel inlet connection to a torque of 20 N·m (15 lb ft).
- Connect the fuel inlet line to the fuel transfer pump and tighten the fuel line nut.
- Turn on the fuel supply and check the fuel system for leaks. Repair any leaks that are present and remove the air from the fuel system. Refer to the Systems Operation, Testing and Adjusting Module, "Fuel System - Prime" topic for additional information.
