N:Pump speed R:Rack position (mm) (1)Tolerance for racks not indicated: +-0.05mm. (2)Supplied with torque spring not set. (3)Set idle at point K (N = N1, R = R1) and confirm that the injection quantity does not exceed Q1 at point J (N = N2). The pre-stroke at that time must be Pr1 (Pv1).

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.

(VR) measurement voltage (I) Part number of the control unit (G) Apply red paint. (H): End surface of the pump Adjustment of the rack sensor (-0720) 1. Rack limit adjustment (1)After mounting the joint (B), select the shim (D) so that the rack position is in the rack limit position. (2)Install the rod (E) to the block (C). (3)At the rack limit, set the distance between the pump end face and the rod (E) to L1. 2. Rack sensor (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 N1. (3)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.) (4)Apply red paint to both the joint (B) and the nut (F) join, and the joint (B) and the pump join. Output voltage VR +-0.01(V), speed N1, rack position Ra, rack sensor supply voltage 5+-0.01 (V)

0000002301 GOVERNOR TORQUE CONTROL

Test data 108622-3451
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.
----------
N1=500r/min N2=(665)r/min N3=(755)r/min N4=1000r/min RF=10.8mm Dr1=0.5mm Dr2=0+0.3mm
