FUEL SUPPLY PUMP INSTALLATION

CAUTION / NOTICE / HINT

Note:

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

  • When replacing the fuel supply pump assembly, common rail assembly, intake manifold or cylinder head sub-assembly, it is necessary to replace the fuel inlet pipe sub-assembly with a new one.

PROCEDURE

  1. INSTALL FUEL SUPPLY PUMP ASSEMBLY

    1. A211306

      Apply a light coat of engine oil to a new O-ring.

    2. Install the O-ring to the fuel supply pump assembly.

    3. A211305

      Install the No. 1 supply pump drive coupling.

      Note:

      When reusing the No. 1 supply pump drive coupling, it must be installed in the same orientation (top/bottom, front/back) as when it was removed.

      Tip:

      Line up the No. 1 supply pump drive coupling with the groove in the camshaft end.

    4. Install the fuel supply pump assembly with the 2 bolts.
