Engine Serial Number LocationThe engine serial number is located on the left hand side of the block above the fuel injection pump.For current engines, the first two characters of the serial number stand for the engine family and type. LD stands for a naturally aspirated 4.236 engine. LJ stands for a turbocharged 4.236 engine. The next five characters are the parts list number. These five characters are represented by dashes "-" in this module. 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. Some new components and improvements have been introduced on the 4.236 and T4.236 engines. If there is a difference in service or specifications, it is noted in this module. The engine cut-in numbers are given for the changes if available.Fuel System
Basic Fuel System Diagram
(1) Fuel injectors (T4.236 injectors shown). (2) Fuel return line from injectors. (3) Cold start heater (thermostart). (4) Fuel return line from fuel filter. (5) Fuel return line from injection pump. (6) Fuel supply line to injection pump. (7) Fuel filter. (8) Fuel lift pump. (9) Water separator. (10) Fuel injection pump. (11) High pressure fuel lines. (12) Fuel tank.When the engine is turning, fuel is pulled from fuel tank (12) through water separator (9) by fuel lift pump (8). When the fuel goes through the water separator, any water in the fuel will go to bottom of the bowl. The fuel lift pump sends the fuel at a low pressure to fuel filter (7). From the fuel filter, the fuel goes through line (6) to fuel injection pump (10). The fuel injection pump sends high pressure fuel through lines (11) to each fuel injector (1), and the fuel injector sprays fuel into the cylinder. Fuel not used by the injection pump goes through line (5) to the inlet side of fuel filter (7).Leakage from the fuel injectors flows through line (2) to the top of fuel filter (7) and back to fuel tank (12).The system must be primed any time any part of the system is drained of fuel. For example, when the fuel filter is 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
