Information:

1 Steam clean the engine. Obtain an SOS sample; be sure the oil is hot and well mixed before you take the sample. Disconnect the batteries.
Do not let the tops of the fuel nozzles turn when the fuel lines are loosened. The nozzles will be damaged if the top of the nozzle turns in the body.
2 Disconnect the fuel injection lines at the nozzles and fuel injection pumps. Install 2F2990 Plugs and 5F2807 Caps on the fuel line connections to keep them free of dirt.3 Disconnect brackets (1) and (2) from the cylinder head and remove the fuel injection lines. Remove clamps (3). 4 Install 6V3129 Nozzle Puller (4). Move the screw out of the puller enough to engage the inside lip of the puller on the lower stepped diameter of the nozzle.
Do not exceed a torque of 17 N m (150 lb.in.) on the screw in tool (4) to remove the nozzle. Added force can cause the stem of the nozzle to bend or break off.
5 With the nozzle bleed screw seen through the clearance hole in tool (4), turn the screw down until the lip of the button goes down into the threads in the hole for the nozzle clamp bolt. Remove each nozzle. If the nozzle cannot be removed with 6V3129 Puller (4), use FT1533 Nozzle Adapter (6) and 1P0074 Slide Hammer (5).
Hold nozzle adapter (6) and slide hammer (5) so the centerline of the tools is the same as the extended centerline of fuel injection nozzle (7). This will prevent the fuel injection nozzle from bending or breaking off.
6 Remove 5F2807 Caps and use slide hammer (5) and nozzle adapter (6) to remove fuel injection nozzle(s) (7). When these tools are used to remove the fuel injection nozzle, the nozzle is not reusable. 7 Use 6V4089 Reamer Assembly (8) to clean the bore for each fuel injection nozzle. Use an open end wrench or a tap driver to turn the reamer.8 Make sure that seal (9) is in position on each nozzle (7). Put washer (10) in place on each nozzle. 9 Install each fuel injection nozzle. Position each nozzle with bleed screw (11) away from the valve cover. Install each clamp.10 Remove 5F2807 Caps and 2F2990 Plugs from the fuel line connections. Connect the fuel injection lines to the nozzles and fuel injection pumps. Tighten the fuel line nuts finger tight only.
Do not let the tops of the fuel nozzles turn when the fuel lines are tightened. The nozzles will become damaged if the top of the nozzle turns in the body.
11 Use 5P0144 Socket and a torque wrench to tighten the nuts to a torque of 40 7 N m (30 5 lb.ft.). Make sure the fuel line clamps are tight. Install the bolts that hold the fuel line brackets to the cylinder head. Loosen clamps (12) and slide the hose on the tube assembly. Remove bolt and breather assembly (13) from the valve cover and remove the seal. 12
