Test data Ex:

0000001801 V-FICD ADJUSTMENT

Adjustment of the V-FICD 1. Adjust the actuator rod to obtain S1. 2. Apply negative pressure P1 kPa {P2 mmHg} to the actuator and confirm that it moves through its full stroke. (A) Control lever (Idling position)
----------
S1=1+1mm P1=-53.3kPa P2=-400mmHg
----------
S1=1+1mm

0000001901 MICROSWITCH ADJUSTMENT

1. Fix dummy bolt (C) at N1 and Q1. 2. Move the microswitch in the direction of the arrow and fix it where it turns OFF. 3. Remove the dummy bolt (C) after the completion of adjustment. Confirm that the microswitch turns ON at the idle lever position and OFF at the full lever position. (A): injection quantity standard (P): Boost pressure (N): Speed of the pump (Q): Injection quantity (B): Microswitch fixing bolt
