PROCEDURE


  1. INSPECT INJECTION TIMING

      *1 Matchmark

      Using a mirror, check that the matchmarks of the injection pump flange and timing belt case are aligned.

  2. ADJUST INJECTION TIMING


    1. A01XGTI

      Loosen the following nuts and bolts.


      1. The bolt holding the injection pump to the injection pump stay.

      2. The 2 nuts holding the injection pump to the timing belt case.

    2. Align the matchmark by slightly tilting the injection pump.

    3. Tighten the following nuts and bolts.


      1. The 2 nuts holding the injection pump to the timing belt case.

        Torque:
        21 N*m  { 209 kgf*cm, 15 ft.*lbf }
      2. The bolt holding the injection pump to the injection pump stay.

        Torque:
        26 N*m  { 265 kgf*cm, 19 ft.*lbf }
  3. INSPECT ENGINE IDLE SPEED


    1. Warm up the engine.

    2. When using the intelligent tester:


      1. Connect the intelligent tester to the DLC3.

        Idle speed
        720 to 820 rpm

        Note


        • Turn all the electrical systems and the A/C off.

        • When checking the idling speed, the shift lever should be in neutral.

        Tech Tips

        Refer to the intelligent tester operator's manual for further details.

      When not using an intelligent tester:


      1. Using SST, connect the tachometer test probe to terminal 9 (TAC) of the DLC3.

        SST
        09843-18040
      2. Check the idle speed.

        Standard idle speed
        720 to 820 rpm

        Note


        • Turn all the electrical systems and the A/C off.

        • When checking the idling speed, the shift lever should be in neutral.

        • Confirm the terminal number before connecting them. Connecting the wrong terminal can be damage the engine.

  4. INSPECT MAXIMUM ENGINE SPEED


    1. Start the engine.

    2. Fully depress the accelerator pedal.

    3. Check the maximum speed.

      Maximum engine speed
      4850 to 4950 rpm
  5. INSPECT COMPRESSION

    Tech Tips

    If there is a lack of power, excessive oil consumption or poor fuel economy is suspected. Measure the compression pressure.


    1. Warm up and stop the engine.

    2. Remove the glow plugs.

    3. Disconnect the spill control valve connector.

    4. Check the cylinder compression pressure.


      1. A01XM9VE05

        Install SST (attachment) to the glow plug hole.

        SST
        09992-00026   ( 09992-00121 )
        Torque:
        13 N*m  { 133 kgf*cm, 10 ft.*lbf }
      2. A01XDUVE05

        Connect SST (compression gauge) to SST (attachment).

        SST
        09992-00026   ( 09992-00121, 09992-00211 )
      3. Fully open the throttle valve, and start the engine.

      4. While cranking the engine, measure the compression pressure.

        Note

        This measurement must be done as quickly as possible.

        Tech Tips

        Always use a fully charged battery to obtain an engine speed of 250 rpm or more.

    5. Repeat the steps above for each cylinder.

      Standard compression pressure
      3138 kPa (32.0 kgf/cm2, 455 psi) or higher
      Minimum pressure
      1961 kPa (20.0 kgf/cm2, 284 psi)
      Difference between each cylinder
      490 kPa (5.0 kgf/cm2, 71 psi) or less

      If the cylinder compression in one or more cylinders is low, pour a small amount of engine oil into the cylinder through the glow plug hole and check the compression pressure for the cylinder with low compression.

      Tech Tips


      • If adding oil helps the compression, the piston rings and/or cylinder bore may be worn or damaged.

      • If the pressure stays low, a valve may be stuck or the seating may be improper, or there may be leakage past the gasket.

    6. Remove SST.

    7. Reinstall the glow plugs.

    8. Reconnect the spill control valve connector.
