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)When air cylinder is operating. (5)Damper spring setting

0000001501 RACK SENSOR

(VR) measurement voltage (I) Part number of the control unit (G) Apply red paint. (H): End surface of the pump 1. Rack sensor adjustment (-0620) (1)Fix the speed control lever at the full position (2)Set the speed to N1 r/min. (If the boost compensator is provided, apply boost pressure.) (3)Adjust the bobbin (A) so that the rack sensor's output voltage is VR+-0.01. (4)At that time, rack position must be Ra. (5)Apply G at two places. Connecting part between the joint (B) and the nut (F) Connecting part between the joint (B) and the end surface of the pump (H)

0000001601 LEVER

1. Air cylinder adjustment (1)With the load lever in the idle position, temporarily set the distance between the load lever A and the air cylinder D at approximately L. (2)Set N1 and apply P1 to the air cylinder D. (3)Adjust set bolt (D) to obtain R1 at the same speed. (4)Lock using nut C. (5)Apply positive pressure several times. (6)Confirm that the load lever A returns to the idling position N2 at pressure P2. (7)Also at P1 confirm R1 (N1).
