  This article mainly introduces how to solve the problem of intermittent alarm and speed limit of 1400RPM when the DX60-9C excavator engine is working.   2023.07 Doosan DMS-5 Data Monitoring System Diagnostic Software     1) Check the instrument panel fault code to display E001382-31C engine speed limit 140ORPM. ;       2) Query the meaning of the code through the fault code table: fuel filter element pressure sensor  identification error;       3) Check the voltage value of the three wires of the fuel filter element pressure sensor. Under normal  conditions, it should be: 0.85W4.9V/0.85L OV/0.85GR 2.3V when normal, when the engine alarms ov.       4) By comparing with the new car, we found that the 0.85GR line should always be around 2.4V, but  when the fault code appears on this car, it is always OV, so it is suspected that the terminal is short- circuited to ground.     Doosan Diagnostic Tool UVIM Support Doosan Excavators High Quality       After investigation, it was found tha

   This article mainly introduces how to solve the walking fault of Doosan DH220-V excavator   Doosan Diagnostic Tool UVIM Support Doosan Excavators High Quality   When the machine is walking in a straight line, the right joystick remains unchanged and the left side  returns to the neutral position (i.e., stops). At this time, the right crawler continues to walk, while the  left crawler slides 800-1000mm before stopping.     1. Checking essentials:   1. After analyzing the hydraulic system, the fault Joints and motors, etc.       02. Measure the system pressure. When the boom is raised to the maximum limit so that the pressure  reaches the maximum, the measured system pressure is 330 BAR, indicating that there is no problem  with the pump.     Doosan Diagnostic Tool DDT G2 SCAN( ECU ,DCU)Software 2016   3. Apply external braking to the walking system. It was also observed that the front pump pressure was  10.5BAR, while the rear pump pressure was 270BAR.       4. After replac
