      *a Torque Wrench Fulcrum Length

      Using SST, tighten the 8 union nuts of the No. 1 and No. 2 injection pipe sub-assemblies.

      Torque:
      Specified tightening torque
      40 N*m  { 408 kgf*cm, 30 ft.*lbf }

      Tech Tips


      • Calculate the torque wrench reading when changing the fulcrum length of the torque wrench.

      • When using SST (fulcrum length of 50 mm (1.97 in.)) + torque wrench (fulcrum length of 180 mm (7.09 in.)): 31 N*m (316 kgf*cm, 23 ft.*lbf)

  5. INSTALL FUEL INLET PIPE SUB-ASSEMBLY

    Note

    When replacing the fuel supply pump assembly, it is necessary to replace the fuel inlet pipe sub-assembly, No. 1 injection pipe clamp and No. 2 injection pipe clamp with a new one. Keep the fuel inlet pipe sub-assembly free of foreign matter.


    1. Temporarily install the fuel inlet pipe sub-assembly.

    2. Install a new No. 1 injection pipe clamp and No. 2 injection pipe clamp with the 2 bolts.
