System Fitting:
The 10083568 field retro-fit kit contains:
- 1 Secondary 4 micron fuel filter assembly.
- 1 Tertiary 4 micron fuel filter assembly.
- Fuel filter brackets.
- Nylon fuel pipe (ECM to Secondary fuel filter).
- Nylon and steel fuel pipe (Leak off / Fuel return).
- Steel fuel pipe (Tertiary fuel filter to HP fuel pump inlet).
- Electric primer filter.
The below notes describe the fitting process required for fitting the rework kit. This assumes the machine is already fitted with a two filter LP fuel system.
Removal of existing components
The secondary fuel filter assembly should be removed by disconnecting the 3 quick connectors (1, 2, & 3). Depress the release button and pull pipe off the spigot. Immediately plug the pipes with a new clean plug. Unbolt and remove the 289-2538 Filter Assembly shown in Image 1.2.1

Install new 335-7051 Bracket (4) reusing the existing bolts and tighten to a torque of 55 Nm +/- 10 Nm. Assemble the 311-1737 Spacer 2 off to the fuel filter bracket using 2 off 6I-0594 M10 flange nuts (1) .
Assemble the 308-7480 Filter (3) to the mounting bracket using (2) 6V-0593 M10 bolts (5) and tighten to a torque of 55Nm +/- 10Nm. See Image 1.3.1.

Leak Off Pipe Assembly
Assemble the 311-1677 Leak Off Pipe to the plate oil cooler in the position shown below.
Connect the quick connector to the fuel pump leak off spigot (1), connect the quick connector to the filter bleed spigot (2) and assemble the steel leak off pipe (3) as follows:
- Assemble the steel injector leak off pipe to the pressure relief valve in the fuel rail (3) using the 277-6165 fuel connection.
- Put the nut then olive onto the pipe end, push the pipe fully into the fitting and tighten the nut by hand.
- Ensure the body of the fitting doesn?t move (using an open ended wrench) and tighten the nut to a torque of 26 Nm +/- 4 Nm for a steel fitting, and tighten to a torque of 21 Nm +/- 4 Nm for brass fittings.(equivalent to 1 1/4 turns).
- Press the pipes into the three clips indicated (5).
- Clip the 311-1919 Bracket (4) onto the pipe next to the tee on the horizontal leg as shown in Fig 1.4.1.

Steel Pipe Assembly
Care must be taken to ensure part cleanliness ? do not remove protective caps until the part is to be installed.
Assemble the 311-1721 steel pipe as shown in Image 1.5.1. Locate both compression fittings as far as possible onto the filter outlet and pump inlet spigots. Tighten all four nuts (two on each compression fitting) to a torque of either 26 Nm +/- 4 Nm for steel fittings, or 21 Nm +/- 4 Nm for brass fittings. (equivalent to 1 1/4 turns)
Where a compression fitting has already been assembled to a spigot, the assembly procedure is modified ? tighten the nut until a sharp rise in torque is felt then tighten an additional 1/6 to 1/3 turns to seal.
A special tool such as a bent spanner will be required
