Test data Ex:
0000001801 W-CSD ADJUSTMENT
Adjustment of the W-CSD
1. Adjustment of the timer stroke
Adjust using screw (A) so that the timer stroke is the value determined using the graph (M). [(K), (M)]
2. Adjustment of the position of the intermediate lever.
Insert a shim (J) L1 between the control lever (I) and the FICD screw (E).
Insert a shim L2 between the control lever (I) and the idle set screw (G).
Align the intermediate lever (F) with the aligning line. Fix the screw (E) so that it contacts the control lever (F). [(K), (L)]
3. Adjustment of the FICD
With the shim (J) inserted, insert a shim L3 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). [(K), (L), (M)]
(O) = timer stroke adjustment (mm) - (1): TA = -0.0215t+0.75
(P) = lever angle (deg) - (2): theta = -0.1925t + 7.71
(Q) = Lever position (mm): L = -0.0635t+2.52
The (Q) indicates the clearance between the control lever and the idle set screw.
(R) = cooling water temperature (deg C)
(S) = cooling water temperature: increase direction
N = pump speed
X = temperature t (deg C)
Y1 = timer stroke TA (mm)
Y2 = control lever angle theta, L (deg mm)
(K) = Figure 1
(L) = Figure 2
(M) = Figure 3
(T) = Timer piston stroke (mm)
(U) = Lever angle (deg)
(W) = Lever position (mm)
