Test data Ex:

Governor adjustment

N:Pump speed R:Rack position (mm) (1)Supplied with damper spring not set. (2)Supply solenoid operating voltage DC24V and move the solenoid body so that the excess lever reaches the excess position at the solenoid's maximum stroke. (3)At excess fuel lever operation: not exceeding EXL (4)Excess fuel setting for starting: SXL (5)Variable speed specification: idling adjustment (6)Main spring setting
----------
EXL=2mm SXL=9.2+-0.1mm

2-stage changeover lever adjustment (A) Speed lever (B) Load lever (C) 2-stage changeover lever (D) Link (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.
