0000001801 POTENTIOMETER ADJUSTMENT

Adjustment of the potentiometer At pump speed N1 and a control lever position a from idle (gap L1), measure the injection quantity and convert it to a voltage value. Then adjust the potentiometer. Voltage conversion formula: V+-0.03 = 0.044Q+2.07 A:Potentiometer performance standards C:Position of the control lever C1:Idle C2:Full speed V:Potentiometer voltage E:Standards for the potentiometer's ON - OFF switch B:Conversion point B1:OFF-->ON B2:OFF-->ON D:Lever opening (from idle) Vi:Applied voltage F:Connecting diagram for the potentiometer G:Output when (2) and (3) connected.

Information:

ACTION REQUIRED
Before completing this Rework Procedure, please review the safety actions in the Operation and Maintenance Manual for your machine.
Choose one of the following actions:
If electronic unit fuel injectors have not failed, reflash the engine ECM with the new software. The new software offers enhanced protection to the fuel system if the fuel/water separator is not drained of water when the Water Separator Full Indicator is displayed.
If electronic unit fuel injectors have failed, replace the injectors and reflash the engine ECM with the new software.
For detailed instructions on removing and installing the injectors, refer to Disassembly and Assembly, UENR0633, "Electronic Unit Injector - Remove" and "Electronic Unit Injector - Install".
