FUEL INJECTOR INSTALLATION

CAUTION / NOTICE / HINT

Note:
  • Always be sure to check the tightening torque.

  • If the pressure lines are leaking after installation, they must be replaced.

  • Do not overtighten the pressure lines.

PROCEDURE

  1. INSTALL INJECTOR ASSEMBLY

    Note:
    • Before installing the injector assembly, check for carbon, foreign matter, etc. on the sealing surfaces of the cylinder head sub-assembly and injector assembly. Clean if necessary.

      Copper Sealing Ring

      Make sure to replace the copper sealing ring on the injector assembly.

    • Before installing the injector assemblies to the injector assembly slots, apply a light coat of highly heat-resistant grease to the area between (A) and (B) shown in the illustration.

    • Check the installation position of the high pressure connection.

    • Make sure to read the adjustment values each time new injector assemblies are installed.

    Tip:
    • Perform "Injector Compensation" after replacing an injector assembly.

    1. Install the 4 injector assemblies to the cylinder head cover sub-assembly.

    2. Step 1:

      Using an E10 "TORX" socket wrench, install the 4 clamping claws to the 4 injector assemblies with the 4 centering rings and 4 bolts.

      Note:

      Make sure the screw centering ring is correctly positioned in order to align the clamping claw.

    3. Step 2:

      Using an E10 "TORX" socket wrench, tighten the 4 bolts.

      Connect the nozzle leakage pipe assembly to the 4 injector assemblies and push down the 4 clips to install the nozzle leakage pipe assembly.

    3. Engage the 2 clamps to connect the wire harness.

  3. INSTALL CAMSHAFT POSITION SENSOR

  4. INSTALL INJECTION PIPE SUB-ASSEMBLY

    Note:
    • If the pressure lines are leaking after installation, they must be replaced.

    • Do not overtighten the pressure lines.

    1. Temporarily install the 2 No. 1 injection pipe sub-assemblies and 2 No. 2 injection pipe sub-assemblies at the common rail assembly end by hand.

    2. A354350N01

      Using SST, tighten 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 shown in the illustration.

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

      • Always reposition SST before it contacts the pressure line.

    3. Using SST, tighten the 4 union nuts at the 4 injector assembly ends of the 2 No. 1 injection pipe sub-assemblies and 2 No. 2 injection pipe sub-assemblies.

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

      • Always reposition SST before it contacts the pressure line.

    4. Check all components of the common rail system for tightness.

  5. CONNECT CABLE TO NEGATIVE BATTERY TERMINAL

    Note:

    When disconnecting the cable, some systems need to be initialized after the cable is reconnected.
