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.
2. Measure the lever angle from the pin hole R (plate).
(A) = lever angle and lever reaction force measuring position
----------
Ya=24.3~28.7mm R=53mm
----------
Ya=24.3~28.7mm R=53mm Alpha=51.5~59.5deg Beta=35~45deg
----------
Ya=24.3~28.7mm R=53mm
----------
Ya=24.3~28.7mm R=53mm Alpha=51.5~59.5deg Beta=35~45deg
0000001901 POTENTIOMETER ADJUSTMENT
Adjustment of the potentiometer
Voltage conversion formula: V+-0.03 = xQ + y (V)
* Measure the injection quantity at N = N1r/min with the control lever position C3 (equivalent to L1 mm).
Determine the voltage with the conversion formula and adjust the potentiometer.
A:Performance standards for the potentiometer
B:Conversion point
C:Position of the control lever
D:Lever opening (from idle)
E:Standards for the potentiometer's ON/OFF switch
Vi:Applied voltage
V:Potentiometer voltage
X:Injection quantity: Q
Y:Voltage (V)
N1:Pump speed
C3:Position of the control lever
L1:Thickness of the shim
C1:Idle
C2:Full-speed
B1:ON-->OFF
B2:OFF-->ON
F:Connecting diagram for the potentiometer
G:Output when (2) and (3) connected.
H:When (4) or (6) connected: switch OFF to ON.
I:When (4) or (5) connected: switch ON to OFF.
J:Output

Information:
Problem
Certain 785 and 789 Trucks may experience problems during cold starts. An Automatic Ether Injection System (AEIS) can be installed to improve starting and combustion during cold startups and increase the service life of the engine.
Affected Product
Model & Identification Number
785 (8GB1-417)
789 (9ZC1-439)
Parts Needed
*For use on machines that DO NOT have Payload Monitor System.**For use on machines that DO have Payload Monitor System.***For machines that have Automatic Electronic Traction Aid.Action Required
If so equipped, remove the existing manual type ether injection system.
Follow the procedure in Special Instruction SEHS9293 "Installation of Automatic Ether Injection System (AEIS) " and install the Automatic Ether Injection System (AEIS).
Service Claim Allowances
This is a 9-hour job.
Parts Disposition
Handle the parts in accordance with your Warranty Bulletin on warranty parts handling.
