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)At delivery (at R = A, N = N1)

Speed control lever angle
F:Full speed
I:Idle
(1)Use the hole at R = aa
(2)Set the idle side stopper bolt so that speed = bb and rack position = cc (at delivery).
(3)Stopper bolt set position 'H'

Plunger assembly number: PL (stamping: ST)
1. Adjustment procedures
(1)Insert the pre-stroke adjusting shims L1 for each cylinder.
(2)Adjust injection quantity.(max. var. bet. cyl. idling a1, full a2)
(3)At basic point A, adjust so that the pre-stroke is L2.
(4)Reconfirm the injection quantity.
