A:Sealing position
B:Pre-stroke actuator
1. When installing the pre-stroke actuator on the pump, first tighten the installation bolts loosely, then move the actuator fully counterclockwise (viewed from the drive side).
Temporary tightening torque: 1 - 1.5 N.m (0.1 - 0.15 kgf.m)
2. Move the actuator in the clockwise direction when viewed from the drive side, and adjust so that it becomes the adjustment point of the adjustment value. Then tighten it.
Tightening torque: 7^9 N.m (0.7^0.9 kgf.m)
3. After prestroke actuator installation adjustment, simultaneously stamp both the actuator side and housing side.

(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.
