(VR) measurement voltage (I) Part number of the control unit (G) Apply red paint. (H): End surface of the pump 1. Rack limit adjustment (1)Mount the joint (B). (2)Select the shim (D) so that the rack limit's rack position is obtained at that time. (3)Install the rod (E) to the block (C). The distance between the pump end face and the rod (E) at rack limit must be L. 2. Rack sensor adjustment (-0020) (1)Screw in the bobbin (A) until it contacts the joint (B). (2)Fix the speed control lever at the full side. (3)Set at speed N. (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 (F). (If equipped with a boost compensator, perform with boost pressure applied.) (5)Adjust the bobbin (A) so that the rack sensor's output voltage is VR+-0.01. (6)Apply G at two places.
