(A): Pre-stroke actuator
(B): Stamp housings A and B at the same time.
(C): Stamping range
1. When installing the pre-stroke actuator on the pump, first tighten the installation bolts loosely, then move the actuator fully clockwise (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 counterclockwise 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.

(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 GOVERNOR TORQUE CONTROL
Dr:Torque control stroke
(A): Without torque control spring capsule
1. Adjustment procedures
(1)Procedure is the same as that for the RFD (former type), except that the positive torque control stroke must be determined at the full lever setting.
2. Procedures for adjustment
(1)Remove the torque control spring capsule.
(2)Operate the pump at approximately N1. (End of idling spring operation < N1.)
(3)Tilt the lever to the full side.
(4)Set so that R = RF.
(5)Increase the speed by pushing in the screw (attached to the bracket on the rear of the tension lever) through the adjusting window.
(6)Adjust so that the torque control stroke Dr1 can be obtained.
(7)Align N2 and N3 with the torque control spring capsule.
3. Final confirmation
(1)After final confirmation, temporarily set the load lever to N = N1, R = idling position.
(2)From this condition, increase speed to N = N4.
(3)Confirm that positive torque control stroke is Dr2.
