FUEL SUPPLY PUMP INSTALLATION

CAUTION / NOTICE / HINT

Note


  • SST A remains in the timing chain cover plate.

  • Always be sure to check the tightening torque.

  • If the pressure lines are leaking after installation, they must be replaced.

  • Do not overtighten the pressure lines.

PROCEDURE


  1. INSTALL FUEL SUPPLY PUMP ASSEMBLY


    1. Install the fuel quantity control valve with the 2 bolts.

      Tech Tips

      Refer to "SPECIFICATIONS - STANDARD BOLT" for the tightening torque.

      *1 Injection Pump Drive Gear

      To insert the fuel supply pump assembly shaft in the injection pump drive gear, it may be necessary to turn the fuel supply pump assembly several degrees so that the spline indicated by the arrow in the illustration and the groove in the fuel supply pump assembly shaft are aligned. Then rotate the fuel supply pump assembly back to the position where the screw can be installed.

    3. Install the fuel supply pump assembly to the cylinder block.

      Note

      Do not damage the shaft, especially the taper.
