FUEL SUPPLY PUMP REMOVAL

CAUTION / NOTICE / HINT

Note


  • When replacing the injectors (including shuffling the injectors between the cylinders), common rail, cylinder head or intake manifold, it is necessary to replace the injection pipes with new ones.

  • w/ DPF:

    When fuel lines are disconnected, air may enter the fuel lines, leading to engine starting trouble. Therefore, perform forced regeneration and bleed the air from the fuel lines.

PROCEDURE


  1. PRECAUTION

      *1 SST (No. 1 adapter)
      *a Service Hole

      Disconnect the pump from the supply pump drive gear.


      1. Install SST (No. 1 adapter) to the timing chain cover.

        SST
        09950-50013   ( 09951-05010, 09952-05010, 09953-05020, 09954-05031, 09955-05010 )

        Note

        Do not use any tools in this procedure.

      2. Rotate the supply pump gear so that the service holes are aligned with SST (No. 1 adapter) as shown in the illustration.
