Test data Ex:

Governor adjustment

N:Pump speed R:Rack position (mm) (1)Tolerance for racks not indicated: +-0.05mm. (2)Set idle at point K (N = N1, R = R1) and confirm that the injection quantity does not exceed Q1 at point J (N = N2). (3)Excess fuel setting for starting: SXL (4)Damper spring setting (5)Variable speed specification: idling adjustment (6)Main spring setting
----------
N1=325r/min R1=3.8mm N2=1100rmin Q1=3mm3/st SXL=9.45+-0.1mm

aa=42mm
----------
a=39deg+-5deg b=43.5deg+-3deg

Stop lever angle

N:Pump normal S:Stop the pump. (1)Rack position = aa (at delivery), set before governor adjustment (2)Set the stopper bolt (apply red paint). (3)Use the pin at R = bb (4)Lever free

0000001501 LEVER

2-stage changeover lever adjustment (A) Speed lever (B) Load lever (C) 2-stage changeover lever (D) Link (E) Bolt (G) Variable speed specifications (H) Minimum maximum speed specifications F:Full speed I:Idle 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.
