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)Damper spring setting
----------
T1=AC91
----------

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=32deg+-5deg b=35.5deg+-3deg

Stop lever angle

N:Pump normal S:Stop the pump. (1)Use the hole at R = aa (2)Set the stopper bolt so that speed = bb and rack position = cc. (Confirm non-injection.) (3)Normal engine position (equivalent to R = dd).
----------
aa=54mm bb=1100r/min cc=3+-0.3mm dd=17.5mm
----------
