(g) rack limit (h) Standard point (i) pump end face (j) Apply red paint. Rack sensor adjustment (154610-0420) 1. Rack limit adjustment (1)Fix the rack at the rack limit position Rl. (2)Attach shim (D) [shim thickness standard (17.5 - R1] to rod (C) and tighten nut (E). (3)Measure the distance X between the end face of the pump and the nut (E), and select a shim (D) so that X = 33-0.2mm. (4)Release the rack, mount the joint (B) and fix. (5)At this time, confirm that the shim (D) does not interfere with the joint (B). 2. Rack limit adjustment (amp-equipped type) (1)Screw in the bobbin (A) until it contacts the joint (B). (2)Fix the speed control lever at the full side and set the pump speed at No r/min. (3)Adjust the depth that the bobbin (A) is screwed in so that the control unit's rack sensor output voltage is VR (V), then tighten the nut (F). (If equipped with a boost compensator, perform with boost pressure applied.) (4)Apply red paint to both the joint (B) and the nut (F) join, and the joint (B) and the pump join.
