Test data Ex:

0000001801 V-FICD ADJUSTMENT

Adjustment of the V-FICD 1. Adjust the actuator rod to obtain L1. 2. Apply negative pressure P1 {P2} to the actuator and confirm that it moves through its full stroke. (A) actuator shaft (B) Control lever
----------
L=1+1mm P1=-53.3kPa P2=-400mmHg
----------
L=1+1mm

0000001901 V-FICD ADJUSTMENT

Adjustment of the V-FICD Becomes L2 when negative pressure P3 {P4} applied to the actuator. To adjust the stroke adjust the actuator's stroke adjusting screw (C). (A) Control lever (B): lock nut (C): stroke adjusting screw (D): Actuator
----------
L2=0.56+-0.2mm P3=-53.3kPa P4=-400mmHg
----------
S=-mm L2=0.56+-0.2mm T=1.2~1.5N-m{0.12~0.15kgf-m}

0000002001 A/T PLATE ADJUSTMENT

A/T plate adjustment 1. Turn the control lever from the idle position (B) to the Full speed position (C) 2. Adjust the A/T plate (D) so that (A)(C) - (A)(B) = L3, then fix.
----------
L3=33+-0.5mm
----------
L1=95.5mm L2=109.5mm L3=33+-0.5mm T=3.5~5N-m(0.35~0.5kgf-m)
