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=AE45 BCL=1.75+-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=35mm
----------
a=27deg+-5deg b=32.5deg+-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=1.5+-0.3mm

Adjustment when mounting the governor. (1)Set the speed of the pump to N1 r/min and fix the control lever at the full set position. (2)Set to full boost. (3)Screw in the aneroid compensator body to obtain the performance shown in the graph above. (4)As there is hysterisis, measure when the absolute pressure drops. (5)Hysterisis must not exceed rack position = h1.
