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 (4)Damper spring setting
----------
T1=AD86 BCL=2.65+-0.1mm
----------

Speed control lever angle

F:Full speed I:Idle (1)Use the pin at R = aa (2)Stopper bolt set position 'H'
----------
aa=32mm
----------
a=4deg+-5deg b=30.5deg+-3deg

Stop lever angle

N:Pump normal S:Stop the pump. (1)Use the pin at R = aa (2)Set the stopper bolt so that speed = bb and rack position = cc. (Confirm non-injection.)
----------
aa=40mm bb=0r/min cc=1+-0.3mm
----------
a=18deg+-5deg b=44deg+-5deg

Timing setting
