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.
