0000001801 W-CSD ADJUSTMENT
Adjustment of the W-CSD
1. Fixing the control lever's starting injection quantity adjusting bolt
Adjust the bolt so that the starting injection quantity is within the adjustment values, then fix.
2. Fixing the CSD lever stopper
At roller holder advance angle a adjust the lever shaft ball pin so that it contacts the roller holder.
At this time, fix the stopper so that the distance from the CSD lever is L1.
3. Fixing the wire CSD lever
Fix the wire at the CSD lever position for timer lift determined from the graph.
4. FICD lever screw adjustment
After fixing the W-CSD lever, move the control lever from the idle position to position b (see figure).
In this position, fix the screw so that the clearance between the control lever and the screw is L as determined from the graph.
Caution: After fixing the screw, the distance must be L2 or more when the control lever and the head of the screw contact at position b. If not L2 or more, replace the screw with a shorter one (select part no. 146620-1400 or 146620-2800).

0000001901 POTENTIOMETER ADJUSTMENT
Adjustment of the potentiometer
At pump speed N1 and at lever angle a from the idle position (shim thickness L), determine the voltage value from the graph using the injection quantity obtained. Then adjust the potentiometer (Applied voltage Vi).
Use block 157829-8700 (5.8mm).
