Test data Ex:

Governor adjustment

N:Pump speed R:Rack position (mm) (1)Tolerance for racks not indicated: +-0.05mm. (2)Excess fuel setting for starting: SXL (3)Damper spring setting (4)When air cylinder is operating.
----------
SXL=11.3+-0.1mm
----------

Timer adjustment

(1)Adjusting range (2)Step response time (N): Speed of the pump (L): Load (theta) Advance angle (Srd1) Step response time 1 (Srd2) Step response time 2 1. Adjusting conditions for the variable timer (1)Adjust the clearance between the pickup and the protrusion to L.
----------
L=1-0.2mm N2=800r/min C2=(8.8)deg t1=2.5--sec. t2=2.5--sec.
----------
N1=750++r/min P1=0kPa(0kgf/cm2) P2=392kPa(4kgf/cm2) C1=8.8+-0.3deg R01=0/4load R02=4/4load

Speed control lever angle

F:Full speed (1)Set the pump speed at aa (2)Set the pump speed at bb. (3)Stopper bolt setting (4)Stopper bolt setting
----------
aa=1275r/min bb=740r/min
----------
a=19.5deg+-5deg b=(8deg)+-5deg

0000001501 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.
----------
N1=500r/min N2=(700)r/min N3=(940)r/min N4=1100r/min RF=R1(10.2)mm Dr1=0.9mm Dr2=0+0.3mm

0000001701 RACK SENSOR

V1:Supply voltage V2f:Full side output voltage V2i:Idle side output voltage (A) Black (B) Yellow (C) Red (D) Trimmer (E): Shaft (F) Nut (G) Load lever 1. Load sensor adjustment (1)Connect as shown in the above diagram and apply supply voltage V1. (2)Hold the load lever (G) against the full side. (3)Turn the shaft so that the voltage between (A) and (B) is V2. (4)Hold the load lever (G) against the idle side. (5)Adjust (D) so that the voltage between (A) and (B) is V2i. (6)Repeat the above adjustments. (7)Tighten the nut (F) at the point satisfying the standards. (8)Hold the load lever against the full side stopper and the idle side stopper. (9)At this time, confirm that the full side output voltage is V2f and the idle side output voltage is V2i.
----------
V1=5+-0.02V V2f=0.15+0.03V V2i=2.35-0.03V
