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
----------
EXL=1.5mm SXL=10.2+-0.1mm
----------

Timer adjustment

(1)Adjusting range (2)Step response time (N): Speed of the pump (L): Load (theta) Advance angle (Srd1) Step response time 1 (Srd2) Step response time 2 1. Adjusting conditions for the variable timer (1)Adjust the clearance between the pickup and the protrusion to L.

Load sensor adjustment (1)Connect as shown in the above diagram and apply supply voltage V1. (2)Hold the load lever (G) against the full side. (3)Turn the shaft so that the voltage between (A) and (B) is V2. (4)Hold the load lever (G) against the idle side. (5)Adjust (D) so that the voltage between (A) and (B) is V2i. (6)Repeat the above adjustments. (7)Tighten the nut (F) at the point satisfying the standards. (8)Hold the load lever against the full side stopper and the idle side stopper. (9)At this time, confirm that the full side output voltage is V2f and the idle side output voltage is V2i.
