Test data Ex:



Governor adjustment

Test data 106671-6661 N:Pump speed R:Rack position (mm) (1)Target notch: K (2)Deliver with positive torque control spring not operating (3)RACK LIMIT (4)Boost compensator stroke: BCL (5)Main spring setting (6)Set idle sub-spring
----------
K=12 BCL=2.15+-0.1mm
----------



Speed control lever angle

Test data 106671-6661 F:Full speed I:Idle S:Stop (1)Use the hole at R = aa
----------
aa=70mm
----------
a=10deg+-5deg b=23deg+-5deg c=31deg+-3deg



Stop lever angle

Test data 106671-6661 N:Pump normal S:Stop the pump. (1)Normal (2)Use the hole at R = aa (3)Speed = bb, rack position = cc (sealed at delivery)
----------
aa=23mm bb=0r/min cc=1-0.5mm
----------
a=15deg+-5deg b=70deg+-5deg



0000001501 TAMPER PROOF

Test data 106671-6661 Tamperproofing-equipped boost compensator cover installation procedure (A): After adjusting the boost compensator, assemble then tighten the bolts to remove the heads. (B): Specified torque (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

Test data 106671-6661 (1)Pump vertical direction (2)Positions of coupling's threaded installation holes at No 1 cylinder's beginning of injection (3)B.T.D.C.: aa (4)-
----------
aa=12deg
