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.

1. Rack sensor adjustment (-0620)
(1)Fix the speed control lever at the full position
(2)Set the speed to N1 r/min.
(If the boost compensator is provided, apply boost pressure.)
(3)Adjust the bobbin (A) so that the rack sensor's output voltage is VR+-0.01.
(4)At that time, rack position must be Ra.
(5)Apply G at two places.
