Part of the Doosan Repair Manuals.
Looking for a Doosan DX230LC shop manual PDF? This is the 818-page factory shop manual for the DX230LC Track Excavator, OEM #950106-00049E, serial number 5001 and Up. The specifications chapter is titled for the DX230LC and its applicable-models table lists that machine alone; the schematic chapters are the shared DX225LC/DX230LC sheets, and several general chapters such as safety, cabin and cylinders also cover neighbouring DX models. You get the full-size hydraulic circuit schematic on page 661 and the full-size electrical wiring schematic on page 792, plus a dedicated hydraulic troubleshooting, testing and adjustment section with the pilot pressure, power mode, swing priority and pressure up procedures. Step-by-step teardown and reassembly covers the swing motor, TM40VD travel motor, cylinders and center joint, with wear limits and seal lists. Main relief is 330 kg/cm² (4,689 psi) and 350 kg/cm² with "Pressure Up"; track link pitch is 190 mm standard, 193 mm at the maintenance limit and 194.5 mm at the replace limit; split flange connections in 1/2" size torque to 2.1 to 2.5 kg•m. Your excavator is not making money parked. Bookmarked and text-searchable, so you can jump straight to the schematic or type the spec you need.
