0000001501 GOVERNOR TORQUE CONTROL

Test data 106871-3980
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=580+-30r/min N3=710+30r/min N4=1100r/min RF=8.5mm Dr1=0.8mm Dr2=0+0.3mm
