(VR) measurement voltage (I) Part number of the control unit (F) Red paint (g) Pump end face 1. Rack limit adjustment (1)Fix the rack at the rack limit position Ra. (2)Select a shim D so that L = 38-0.2 mm and install rod C. (3)Release the rack fixing and mount the joint (B) and fix. (4)At this time, confirm that the shim (D) does not interfere with the joint (B). 2. Rack sensor adjustment (154610-4*20) (1)Screw in the bobbin (A) until it contacts the joint (B). (2)Fix the speed control lever at the full side. (3)Set the speed to N1 r/min. (4)Adjust the depth that the bobbin (A) is screwed in so that the control unit's rack sensor output voltage is VR+-0.01 (V), then tighten the nut (E). (5)Adjust the bobbin (A) so that the rack sensor's output voltage is VR. (6)Apply at 2 locations (F). Joint B and nut E join Joint B and pump end face G join

Tamperproofing-equipped boost compensator cover installation procedure (A): After adjusting the boost compensator, assemble then tighten the bolts to remove the heads. (B): Specified torque (1)Before adjusting the governor and the boost compensator, tighten the screw to the specified torque. (Tightening torque T = T1 maximum) (2)After adjusting the governor and the boost compensator, tighten to the specified torque to break off the bolt heads. (Tightening torque T = T2)
