Test data Ex:

0000001801 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. 2. Adjustment of the position of the intermediate lever. (1)Insert a shim L1 between the control lever (F) and the idle set screw (G). (2)Set intermediate lever (D) adjusting screw (E) so that adjusting screw (E) contacts control lever, and so that when intermediate lever is at right angles to pump center, intermediate lever and idle stopper bracket (H) overlap at position (J). 3. W-CSD adjustment Insert a shim L1+-0.05 between the control lever (F) 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 (D) via the rod (I).
