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)Adjust so that the boost compensator pushrod protrusion R = Ra at 0 boost.
----------
T1=L05 BCL=1.65+-0.1mm Ra=12+-0.5mm
----------

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=11deg+-5deg b=35deg+-3deg

Stop lever angle

N:Pump normal S:Stop the pump. (1)Use the pin at R = aa
----------
aa=45mm
----------
a=12.5deg+-5deg b=40deg+-5deg

Timing setting

(1)Pump vertical direction (2)Position of timer's threaded hole at No 1 cylinder's beginning of injection (3)B.T.D.C.: aa (4)-
