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.

0000002201 RACK SENSOR
(VR) measurement voltage
(I) Part number of the control unit
(G) Apply red paint.
(H): End surface of the pump
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.

0000002301 AIR CYLINDER
(A): Speed lever
(B): Adjusting bolt
(C): Air cylinder
(D): Locknut
Adjustment of the air cylinder
1. Set the speed lever at the idling position.
2. Set the gap between the air cylinder (a) and the set bolt (b) to L1.
3. Set speed at N1 and apply positive pressure P1 to the air cylinder (c). Read the rack position value at the same speed.
4. Slowly push the set bolt (b) out and fix it using the nut (d) when the rack position is R1 at N1.
5. Apply positive pressure several times and confirm that the lever returns to the idle position at positive pressure P2.
6. Also, at positive pressure P1confirm that the rack position is R1 and complete adjustment.
