Required Tools    
Tool    Part Number    Part Description    Qty    
A     6V-6980     Fuel Nozzle Puller     1    
B     FT-1533     Adapter     1    
1P-0074 Slide Hammer Puller     1    Start By:
Remove the fuel injection lines. Refer to Disassembly and Assembly, "Fuel Injection Lines - Remove and Install".
Keep all parts clean from contaminants.Contaminants may cause rapid wear and shortened component life.
Do not allow the tops of the fuel injector nozzles to turn while the fuel lines are loosened. The fuel injector nozzles will be damaged if the tops of the fuel injector nozzle turns in the body. Defective fuel injector nozzles will damage the engine due to incorrect spray patterns.

Remove bolt (1) and the clamp that secures the fuel injector nozzle.
Illustration 2 g00448821
Install Tool (A) over the fuel injector nozzle. Turn screw (2) counterclockwise until the button on the end of the screw is just above the bolt hole for the clamp that holds down the fuel injector nozzle.
Tilt Tool (A) upward so that the inside lip of the fuel nozzle puller is under the diameter of the fuel injector nozzle.
Turn screw (2) clockwise until the button on Tool (A) goes into the bolt hole for the clamp that holds down the fuel injector nozzle.
Do not exceed the recommended torque on the screw of the 6V-6980 Fuel Nozzle Puller in order to remove the nozzle. The nozzle will bend or break if a torque greater than 17 N m (13 lb ft) is applied.
Turn screw (2) clockwise in order to lift the fuel injector nozzle out of the bore. After the fuel injector nozzle is loose in the bore of the cylinder head, move the fuel injector nozzle upward and move the fuel injector nozzle downward. Moving the fuel injector nozzle helps to loosen any carbon buildup and aids in the removal of the fuel injector nozzle.
When Tool (A) is used to remove the fuel injector nozzles, remove the carbon dam seal on the end of the fuel injector nozzle.
Illustration 3 g00448822
If the fuel injector nozzle cannot be removed with Tool (A), Tool (B) must be used.Note: When Tool (B) is used, it is likely that the fuel injector nozzle cannot be used again. A new fuel injector nozzle will need to be installed as a replacement.Note: Align the centerline of Tool (B) with the extended centerline of fuel injector nozzle (3). This procedure will help prevent distortion of the fuel injector nozzle which can cause the fuel injector nozzle to bend or break.
Remove the protective cap and install Tool (B) .
Use the slide hammer in order to remove fuel injector nozzle (3) .
Remove the compression seal from the fuel injector nozzle.
