Part of the Doosan Repair Manuals.
One book, two machines: this is the factory shop manual for the Doosan DX340LC-5 and DX350LC-5 crawler excavators, publication 950106-01001E, 1st Edition April 2014. If you run either one, you are covered. These are Tier 4 Final machines with the Scania-built Doosan DC 9, a five cylinder in-line diesel rated 237 kW (318 HP) at 1,800 rpm - not the DL 06P from the smaller Doosans and not the DC 13 from the bigger ones, so make sure your other references match. Inside: full engine teardown chapters, main pump and main control valve, swing device, travel gear, hydraulic and electrical systems, plus oversize schematic foldouts at pages 1629 to 1631 and six A3 electrical sheets at pages 551 to 556.
