0000001801 V-FICD ADJUSTMENT

Adjustment of the V-FICD (perform with W-FICD released) 1. Adjust to obtain L1. 2. Set at L2 when negative pressure P1 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)

0000001901 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 (W). [(K), (M)] 2. Adjustment of the position of the intermediate lever. With a shim L inserted between the control lever (I) and the FICD set screw (E), insert a shim L1 between (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 control lever (I). [(U), (V)] 3. Adjustment of the FICD Insert a shim L1 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 position (deg) (Q) lever position (mm) The (Q) indicates the clearance between the control lever and the idle set screw.
