Test data Ex:

0000001801 W-CSD ADJUSTMENT

Test data 104749-6420
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. X = temperature t Y1 = timer stroke TA Y2 = control lever angle theta, L (deg, mm) (K) = aligning mark (U) = diagram 1 (V) = diagram 2 (W) = diagram 3
