Part of the Doosan Repair Manuals.
This is the factory shop manual for the 2010 Doosan DX700LC, the 70 tonne flagship of the line, publication 950106-00013E. It covers the Isuzu 6WG1-TC engine, the full hydraulic circuit from main pump and regulator through the main control valve, swing motor, travel motors and reduction gears, plus cabin and counterweight removal, track assembly wear limits, and boom and arm pin work. You get the complete hydraulic schematic (SP002147, page 997), the complete electrical schematic (SP002189, page 1125), and the machine side failure code list on page 1046. Torque tables, pressure settings, disassembly drawings and testing procedures are all here. If you keep one of these big diggers earning, this is the book the dealer techs work from.
