CAUTION / NOTICE / HINT

Note

When replacing the injector assemblies (including exchanging the injector assemblies between the cylinders), common rail assembly, intake manifold or cylinder head, it is necessary to replace the injection pipe sub-assemblies with new ones.

Tech Tips

After replacing any of the injector assemblies, perform both the "Injector Compensation" and the "Pilot Quantity Learning Values Reset" functions using the GTS.

      *1 No. 1 Injection Pipe Sub-assembly
      *2 No. 2 Injection Pipe Sub-assembly
      *3 No. 3 Injection Pipe Sub-assembly

      Using a 17 mm union nut wrench, separate the union nut from the injector assembly first, then from the common rail assembly.

    2. Remove the No. 1 injection pipe sub-assembly.

  4. REMOVE NO. 2 INJECTION PIPE SUB-ASSEMBLY

    Tech Tips

    Perform the same procedure as for the No. 1 injection pipe sub-assembly.

  5. REMOVE NO. 3 INJECTION PIPE SUB-ASSEMBLY

    Tech Tips

    Perform the same procedure as for the No. 1 injection pipe sub-assembly.

  6. REMOVE NO. 1 GLOW PLUG CONNECTOR


    1. A01M1TF

      Remove the 5 screw grommets.

    2. A01LV9K

      Remove the nut and disconnect the glow terminal.

    3. Remove the 4 nuts and No. 1 glow plug connector.

  7. REMOVE NO. 2 INTAKE MANIFOLD INSULATOR


    1. A01LYU9

      Remove the No. 2 intake manifold insulator.

  8. REMOVE NOZZLE LEAKAGE PIPE ASSEMBLY


    1. A01LWJ8

      Disconnect the 4 connectors from the 4 injector assemblies.

    2. A01M36DC04
      *a Lock Bush

      Pull up the lock bush as shown in the illustration and separate the nozzle leakage pipe assembly.

      Note

      Do not separate the nozzle leakage pipe assembly by pulling on the hose portion. Separate it while holding onto the lock bush portion.

  9. REMOVE NO. 1 NOZZLE HOLDER CLAMP


    1. A01LYARC01
      *1 Nozzle Holder Clamp
      *2 Nozzle Holder Clamp Seat
      *3 Washer

      Remove the 4 bolts, 4 washers and 4 nozzle holder clamps.

  10. REMOVE NOZZLE HOLDER CLAMP SEAT


    1. A01LYB3

      Remove the 4 nozzle holder clamp seats form the cylinder head.

  11. REMOVE INJECTOR ASSEMBLY


    1. A01M23X

      Remove the 4 injector assemblies from the cylinder head.

      Note


      • Each injector assembly has its own fuel injection part number. When replacing the injector assemblies, store them in the correct order so that they can be returned to their original locations when reassembled.

      • Arrange the injector assemblies, clamps, washers, bolts and clamp seats in the correct order.

  12. REMOVE INJECTION NOZZLE SEAT


    1. A01M0XN

      Remove the 4 injection nozzle seats from the injector assemblies or cylinder head.

      Note

      When removing the injector assembly, check that the injector nozzle seat is either attached to the injector assembly, or remains in the cylinder head.
