ACS adjustment
Full load injection quantity at high altitudes and ACS adjusting method
1. Full load injection quantity adjustment
(1)Remove the ACS cover and remove the bellows and adjusting shim.
(2)Perform all adjustments as per the adjustment standard except for ACS adjustment.
2. ACS adjustment
(1)Assemble the ACS cover, bellows and adjusting shim.
(2)At pump speed N1, adjust using a shim to obtain the decrease for the altitude shown in the table.
X1 = atmospheric pressure
X2 = altitude
Y = decrease quantity
(A) = adjustment value

0000001801 W-CSD ADJUSTMENT
Adjustment of the W-CSD
1. CSD adjusting screw adjustment
Adjust so that the adjusting screw (A) protrusion is L1, then confirm. (U)
2. Adjustment of the position of the intermediate lever.
Insert a shim L2 between the control lever (I) and the FICD screw (E).
With the shim inserted, insert a shim L3 between the control lever (I) and the idle set screw (G). Align intermediate lever (F) with the aligning mark and fix screw (E) so that it contacts the control lever. [(U), (V)]
3. Adjustment of the FICD
With a shim L2 inserted, insert a shim L4 between the control lever and the idle set screw (G).
Use adjusting screw (B) to fix the CSD lever (C) in the position where it operates the intermediate lever (F) via the rod (D). [(U), (V), (W)]
(P) = Lever angle (deg): theta = 0.1925t+6.65
(Q) = Lever position (mm): L = -0.0635t+2.19
(R) = (Q) shows the distance between the control lever and the idle set screw.
