Test data Ex:
0000001801 CONTROL LEVER ANGLE
Control lever angle measurement
1. Measure dimension Ya between the end of the lever and the flange face B.
2. Measure the lever angle from the R (plate) pin hole.
(A) Lever angle measurement position
----------
Ya=8.4~12.2mm R=53mm
----------
Ya=8.4~12.2mm R=53mm Alpha=51.5~59.5deg Beta=31~41deg
----------
Ya=8.4~12.2mm R=53mm
----------
Ya=8.4~12.2mm R=53mm Alpha=51.5~59.5deg Beta=31~41deg
0000001901 POTENTIOMETER ADJUSTMENT
Adjustment of the potentiometer
Measure the injection quantity with the control lever a from the idle position (equal to shim thickness L1) at pump speed N5. Install the potentiometer so that injection quantity and output voltage correspond as shown in the graph.
J = formula
A = shim thickness
C = control lever angle
E = adjusting point
Vi = applied voltage
V = potentiometer voltage
X = injection quantity Q
Y = voltage (V)
C2 = idle
C3 = full speed
F = potentiometer circuit diagram
G = output
N = pump speed
Q = injection quantity
1 = black
2 = blue yellow
3 = blue red
----------
