(I) Part number of the control unit
(G) Apply red paint.
(H): End surface of the pump
1. Rack limit adjustment
(1)Fix the rack at the rack limit position Ra.
(2)Install the shim (D) to the rod (C) and tighten nut (E).
(3)Select a shim (D) so that the distance between the end surface of the pump and the nut (E) is L.
(4)Release the rack fixing and mount the joint (B) and fix.
(5)At this time, confirm that the shim (D) does not interfere with the joint (B).
2. Rack sensor adjustment (-0420)
(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 (F).
(5)Adjust the bobbin (A) so that the rack sensor's output voltage is VR.
(6)Apply G at two places.
