Test data Ex:

Governor adjustment

N:Pump speed R:Rack position (mm) (1)Notch fixed: K (2)Tolerance for racks not indicated: +-0.05mm. (3)Boost compensator stroke (4)Set idle sub-spring (5)Main spring setting (6)Rack difference between N = N1 and N = N2
----------
K=9 N1=1000r/min N2=400r/min
----------

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=1.5-0.2mm N2=800r/min C2=(10deg) t1=2.5--sec. t2=2.5--sec.
----------
N1=750++r/min P1=0kPa(0kgf/cm2) P2=392kPa(4kgf/cm2) C1=10+-0.3deg R01=0/4 load R02=4/4 load

----------

----------
a=(1deg)+-5deg b=(18deg)+-5deg

Stop lever angle

N:Pump normal S:Stop the pump. (1)No return spring (2)Set the outer screw where it contacts the inside (seal at delivery) (3)Rack position = aa, speed = bb (stamp at delivery) (4)Use the hole above R = cc
----------
aa=1-0.5mm bb=0r/min cc=17mm
----------
a=14deg+-5deg b=70deg+-5deg

0000001501 SPEED SENSOR

(A) Flyweight projection (B) Pickup sensor (c) Lock nut Speed sensor installation (1)Install the speed sensor so that the clearance between the sensor and the flyweight projection is L. (This gap is the gap when the pickup sensor is returned 1.5 turns from where it contacts the flyweight tooth.)
----------
L=1.3~1.5mm
----------

0000001601 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. Connecting part between the joint (B) and the nut (F) Connecting part between the joint (B) and the end surface of the pump (H)
----------
N1=1000r/min Ra=14mm
----------

0000001701 TAMPER PROOF

Tamperproofing-equipped boost compensator cover installation procedure (A) After adjusting the boost compensator, tighten the bolts to remove the heads. (1)Before adjusting the governor and the boost compensator, tighten the screw to the specified torque. (Tightening torque T = T1 maximum) (2)After adjusting the governor and the boost compensator, tighten to the specified torque to break off the bolt heads. (Tightening torque T = T2)
----------
T1=2.5N-m(0.25kgf-m) T2=2.9~4.4N-m(0.3~0.45kgf-m)
----------

Timing setting
