OIL PUMP (for DPF) INSPECTION


  1. INSPECT OIL PUMP RELIEF VALVE


    1. A01DVCEE01

      Coat the relief valve with engine oil and drop it into the relief valve hole.

    2. Check that the relief valve falls in smoothly by its own weight.

      If it does not, replace the relief valve. If necessary, replace the timing gear case assembly.

  2. INSPECT OIL PUMP


    1. A01DW0ZE04
      Text in Illustration
      *1 Alignment Mark

      Install the driven rotor to the timing gear case with the mark facing the cylinder block side.

    2. A01E2NDE01

      Check the tip clearance.


      1. Using a feeler gauge, measure the clearance between the drive and driven rotor tips.

        Standard tip clearance
        0.060 to 0.160 mm (0.0024 to 0.0063 in.)
        Maximum tip clearance
        0.21 mm (0.0083 in.)

        If the tip clearance is more than the maximum, replace the timing gear case assembly.

    3. A01DYL0E01

      Check the body clearance.


      1. Using a feeler gauge, measure the clearance between the oil pump body and driven rotor.

        Standard body clearance
        0.100 to 0.170 mm (0.0039 to 0.0066 in.)
        Maximum body clearance
        0.20 mm (0.0079 in.)

        If the body clearance is more than the maximum, replace the timing gear case assembly.

    4. A01E1TWE01

      Check the side clearance.


      1. Using a feeler gauge and precision straightedge, measure the clearance between the rotor and precision straightedge.

        Standard side clearance
        0.030 to 0.090 mm (0.0012 to 0.0036 in.)
        Maximum side clearance
        0.15 mm (0.0059 in.)

        If the side clearance is more than the maximum, replace the timing gear case assembly.
