Test data Ex:
0000001801 V-FICD ADJUSTMENT
Adjustment of the V-FICD (perform with W-FICD released)
1. Adjust to obtain L1.
2. Confirm that L2 is obtained when negative pressure P1 (kPa) {P2 (mmHg)} is applied to the actuator.
Adjust the stroke using the actuator stroke adjusting screw (F).
(A): Pin
(B): Actuator shaft
(C): Control lever
(D): Actuator
(E): Lock nut (torque T)
----------
L1=1+1mm L2=1.45+-0.1mm P1=-53.3kPa P2=-400mmHg
----------
L1=1+1mm L2=1.45+-0.1mm T=1.2~1.5N-m{0.12~0.15kgf-m}

0000001901 W-CSD ADJUSTMENT
Adjustment of the W-CSD
1. Adjustment of the timer stroke
Adjust screw (A) so that the timer stroke is the value determined from the graph (W) [(V), (W)].
2. Adjustment of the position of the intermediate lever.
Insert a shim L3 between the control lever (I) and the idle screw (G).
Align the intermediate lever (F) with the aligning mark (J) and then fix the intermediate lever adjusting screw (E) so that (E) contacts the shim between (E) and (I). [(U), (V)]
3. Adjustment of the FICD
Insert a shim L4 between the control lever (I) 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)]
(O) Timer stroke adjustment (mm)
(P): lever angle (deg)
(Q): lever angle (deg)
The (Q) indicates the clearance between the control lever and the idle set screw.
X:Temperature t (deg C)
Y1:Timer stroke TA (mm)
Y2:Control lever position at theta L (deg, mm)
(R): cooling water temperature (deg C)
(S): cooling water temperature: increase direction
N:Pump speed
(M): timer piston stroke (mm)
(K): colored ring
(Z): lever position (mm)
