(E) Bolt
1. Minimum-maximum speed specification adjustment (when running)
(1)After completing governor adjustment, hold the 2-stage changeover lever (C) so that the speed lever (A) contacts the full speed stopper.
(2)In this condition, the load lever is held in the idle position.
(3)Adjust bolt (E) so that the clearance between the pin underneath lever (C) and the end of the long groove in link (D) is L.
(4)Lock using the nut.
2. Variable speed specification adjustment (at operation)
(1)Hold the 2-stage changeover lever (C) so that the load lever (B) contacts the full load stopper. (When the load lever is equipped with a cancel mechanism, move it so that it contacts the stopper without canceling.)
(2)In this condition, confirm that the speed lever (A) moves from idle to full speed.

Information:
1. Disconnect electrical plug (1) and throttle linkage (2).2. Disconnect six fuel lines (3) from injection pump. 3. Remove inspection plate (5) from the timing gear cover. 4. Make an alingment of the timing marks on fuel injection pump gear (7) and idler gear (6), or put identification marks on the gears for correct installation. 5. Remove three bolts (8) that hold the fuel injection pump drive gear to the fuel injection pump.
Typical Example6. Put alignment marks on the fuel injection pump and the timing gear case cover as shown. Remove three nuts (9) and washers that hold the fuel injection pump in place. Remove fuel injection pump (10). Remove the gasket from the timing gear case. The following steps are for the installation of the fuel injection pump.7. Put the gasket for fuel injection pump (10) in position on the timing gear case. 8. Position the fuel injection pump; be sure dowel (11) in fuel injection pump gear (7) is in alignment with the groove (slot) in the fuel injection pump shaft when the fuel injection pump is put in position.
Typical Example9. For initial fuel injection pump timing, make an alignment of the reference marks on the fuel injection pump and the timing gear case. Install the three nuts (9) and washers that hold fuel injection pump (10) in place. 10. Be sure the timing marks or the marks that were put on the fuel injection pump gear and idler gear are in alignment. Install three bolts (8) that hold the fuel injection pump gear to the fuel injection pump. 11. Install plate (5) with a new gasket.12 Connect all fuel lines (3), control linkage (2) and electrical plug (1).13. Prime the fuel system. See the MAINTENANCE MANUAL.
