PROCEDURE


  1. PRECAUTION

    Note


    • After the engine has stopped, wait at least 1 minute before releasing the high pressure lines.

    • When working on the fuel circuit, protect the generator assembly against contamination. Cover the generator assembly with suitable materials. Failure to comply with this procedure may result in a generator assembly malfunction.

    • B004254N01

      After disconnecting the pressure line, it is absolutely essential to seal the injector assemblies and the common rail assembly with SST.

  4. REMOVE ENGINE COVER


    1. B0044OE

      Remove the engine cover.

  5. REMOVE INJECTION PIPE SUB-ASSEMBLY

    Note


    • Be careful not to bend the pressure line with SST.

    • Always reposition SST before it contacts the pressure line.


    1. B0043S6N01

      Using SST, loosen the 4 union nuts at the common rail assembly end of the 2 No. 1 injection pipe sub-assemblies and 2 No. 2 injection pipe sub-assemblies.

  7. DISCONNECT NOZZLE LEAKAGE PIPE ASSEMBLY


    1. B0043DM

      Disengage the 2 clamps to disconnect the wire harness.

    2. B00450XC01
      *1 Sealing Ring
      *a Leakage Line
      *b Clip
      *c Pull up

      Pull up the 4 clips and disconnect the nozzle leakage pipe assembly from the 4 injector assemblies as shown in the illustration.

      Note

      If a sealing ring is damaged, the entire leakage line must be replaced.

    3. Remove the 4 sealing rings from the nozzle leakage pipe assembly.

  8. REMOVE INJECTOR ASSEMBLY


    1. B00435I

      Disconnect the 4 injector assembly connectors.

    2. B0042WB

      Using an E10 "TORX" socket wrench, remove the 4 bolts and 4 centering rings.

    3. Remove the 4 clamping claws from the 4 injector assemblies.

    4. B00422BN01

      Remove the 4 injector assemblies from the cylinder head cover sub-assembly.


      1. While lightly rotating the injector assembly back and forth, remove the injector assembly.

        Note

        Do not rotate the injector assembly (rod) more than a few degrees.

        Tech Tips

        If the injector assembly cannot be easily removed, mount SST (rod) to the pressure line connection.
