COMMON RAIL (w/o DPF) REMOVAL

Note


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

  • When replacing the fuel supply pump, common rail, cylinder block, cylinder head, cylinder head gasket or timing gear case, it is necessary to replace the fuel inlet pipe with a new one.

  • After removing the injection pipes and fuel inlet pipe, clean them with a brush and compressed air.


  1. DISCONNECT CABLE FROM NEGATIVE BATTERY TERMINAL

    Note


    • After turning the ignition switch off, waiting time may be required before disconnecting the cable from the battery terminal. Therefore, make sure to read the disconnecting the cable from the battery terminal notice before proceeding with work Click here.

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