Test data Ex:

0000001801 POTENTIOMETER ADJUSTMENT

Adjust the potentiometer so that the output voltage is V1 at the idle lever position (applied voltage Vi).
----------
V1=1.3+-0.03V Vi=10V
----------

0000001901 V-FICD ADJUSTMENT

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

0000002001 A/T PLATE ADJUSTMENT

A/T plate adjustment Adjust the A/T plate (A) so that (A)(C) - (A)(B) = L3 when the control lever is moved from the idle position (B) to the full speed position (C), then fix. (B) Idle position (C) Full
----------
L3=32.9+-1mm
----------
L1=36mm L2=174mm

0000002101 STARTING I/Q ADJUSTMENT

Starting injection quantity adjustment Adjust adjusting bolt (A) so that the start injection quantity is within the specifications and fix using nut (B). (Torque T) Make bolt protrusion L.
----------
L=3~6mm T=3.4~4.9N-m(0.35~0.5kgf-m)
----------
L=3~6mm T=3.4~4.9N-m(0.35~0.5kgf-m)
