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=AE83 BCL=2.4+-0.1mm
----------

Speed control lever angle

F:Full speed I:Idle (1)Use the hole at R = aa (2)Stopper bolt set position 'H' (3)Viewed from feed pump side.
----------
aa=37.5mm
----------
a=2deg+-5deg b=37deg+-3deg

Stop lever angle

N:Pump normal S:Stop the pump. (1)Use the hole at R = aa (2)Normal engine position (equivalent to R = bb). (3)Set the stopper bolt so that speed = cc and rack position = dd (and confirm non-injection).
----------
aa=54mm bb=18mm cc=1100r/min dd=3.5+-0.3mm
----------
a=(20.5deg) b=29.5deg+-5deg c=40deg+-5deg

Timing setting
