  1. Temporarily install the injection pipe.

  1. Using the SST, first tighten the nut at the common rail end of the injection pipe.

    SST
    09023-38401
    Torque:
    27 N*m{275 kgf*cm, 20 ft.*lbf}
    HINT:
    1. Use of the proper SST is necessary to ensure that the correct torque is applied to the injection pipe nut.
    2. Use a torque wrench with a fulcrum length of 30 cm (11.81 in.).
    3. Make sure that the pipe is not deformed or twisted during installation.
      If the pipe is deformed or twisted, or if it cannot be installed properly, replace the pipe with a new one.
