      *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.

      Tech Tips

      When installing a new fuel supply pump assembly, adjust the fuel supply pump assembly and injection pump drive gear alignment by turning the fuel supply pump assembly 45° clockwise (top view).
