Test data Ex:

Governor adjustment

N:Pump speed R:Rack position (mm) (1)Torque cam stamping: T1 (2)Tolerance for racks not indicated: +-0.05mm. (3)Boost compensator stroke: BCL
----------
T1=AD83 BCL=1.25+-0.1mm
----------

Speed control lever angle

F:Full speed I:Idle (1)Use the hole at R = aa (2)Stopper bolt set position 'H'
----------
aa=40mm
----------
a=20deg+-5deg b=37deg+-3deg

Stop lever angle

N:Pump normal S:Stop the pump. (1)Set the stopper bolt at rack position = aa, speed = bb and confirm non-injection. (2)- (3)Use the pin above R = cc
----------
aa=1.5+-0.3mm bb=0r/min cc=40mm
----------
a=12deg+-5deg b=44deg+-5deg
