ENGINE SERIAL NUMBER LOCATIONThe engine serial number is located on the left hand side of the block below the fuel injection pump on the auxiliary drive housing.The first two characters of the serial number stand for the engine family and type. TW stands for a naturally aspirated 6.3544 Engine. TU stands for a turbocharged 6.3544 engine. The next five characters are the parts list number. The next single letter is the country of origin. The next set of numbers is the production serial number, and the last letter is the year of manufacture.Fuel System
BASIC FUEL SYSTEM DIAGRAM 1. Fuel injectors (atomisers).2. Fuel return line from injectors.3. Cold start heater (thermostart).4. Fuel return line from secondary filters.5. High pressure fuel lines.6. Fuel injection pump.7. Fuel return line from injection pump.8. Fuel transfer pump.9. Fuel supply line to injection pump.10. Secondary filters.When the engine is turning, fuel is pulled from the fuel tank through a water separator by fuel transfer pump (8). When the fuel goes through the water separator, any water in the fuel will go to the bottom of the bowl. The fuel transfer pump sends the fuel at a low pressure to secondary filters (10). From the secondary filters, the fuel goes through line (9) to fuel injection pump (6). The fuel injection pump sends high pressure fuel through lines (5) to each fuel injector (1), and the fuel injector sprays fuel into the cylinder. Fuel not used by the injection pump goes through line (7) back to the inlet side of secondary filters (10).Leakage from the fuel injectors flows through line (2) to the top of secondary filters (10) and back to the fuel tank.The fuel injection pump needs fuel for lubrication. The precision parts of the pump are easily damaged. For this reason, the engine must NOT be started until the injection pump is full of fuel that is free of air.The system must be primed any time any part of the system is drained of fuel. For example, when the secondary filters are changed or a fuel line is removed, the inspection cover on the fuel injection pump is removed to check timing, or the injection pump is removed for service or repair, the fuel system must be primed (air removed).
