Troubleshooting The Fuel Injection Nozzles On The Engine
Note: Be careful when you are handling the fuel injection nozzles in order to prevent damage to the orifices, the threads, and other surfaces. When a fuel injection nozzle is installed, make sure that all surfaces and threads are clean.Only personnel that have the proper training should disassemble the fuel injection nozzles. Only personnel that have the proper training should perform repairs to the fuel injection nozzle. Replace the fuel injection nozzle if the fuel injection nozzle cannot be adjusted in order to operate correctly.Refer to the Specifications Module, "Fuel Injection Nozzles" topic for additional information.Problem 1: The engine is difficult to start. If the engine starts, the engine runs rough.
Probable Cause
The fuel injection nozzle does not seal correctly in the cylinder head. Make sure that the gaskets, the insert and the mating surface of the cylinder head are clean. Make sure that the fuel injection nozzle is tightened to the correct torque in the threaded hole of the cylinder head.
There is debris on the mating surface of the cylinder head with the gaskets or the insert. Make sure that extra gaskets were removed from the threaded recess in the cylinder head for the fuel injection nozzle. Remove any extra gaskets or debris.
The connections of the high pressure fuel line leak. Tighten the fittings of the high pressure fuel line.
The fuel injection nozzle does not operate correctly. Make sure that the components of the fuel injection nozzle are tightened to the correct torques. Make sure that the gaskets and the insert are positioned correctly. Test the fuel injection nozzle on a nozzle tester in order to measure the pressure setting.
The incorrect fuel injection nozzle is installed. Make sure that all fuel injection nozzles are the correct replacement parts for the engine. Refer to the Parts Manual for the correct replacement part.Problem 2: The engine exhaust has too much black smoke.
Probable Cause
Extra gaskets were not removed from the threaded recess in the cylinder head for the fuel injection nozzle. There is debris on the mating surface of the cylinder head with the gaskets or the insert. Remove any extra gaskets or debris.
The fuel injection nozzle does not operate correctly. Make sure that the components of the fuel injection nozzle are tightened to the correct torques. Make sure that the gaskets and the insert are positioned correctly. Test the fuel injection nozzle on a nozzle tester in order to measure the pressure setting.
The incorrect fuel injection nozzle is installed. Make sure that all fuel injection nozzles are the correct replacement parts for the engine. Refer to the Parts Manual for the correct replacement part.Problem 3: The engine has lost power and the engine uses too much fuel.

The incorrect fuel injection nozzle is installed. Make sure that all fuel injection nozzles have the correct code for the engine.
A connection of the fuel return line leaks. Inspect all connections of the low pressure fuel line for tightening to the correct torque.Problem 4: The engine has the following symptoms: the engine knocks, the engine does not run evenly, and the engine misfires.
