Part of the Doosan Repair Manuals.
Looking for the Doosan DX15, DX18 shop manual PDF? All 513 pages of this factory shop manual (OEM #K1043970AE) cover your DX15 or DX18 track excavator, from track assembly to boom and bucket. You get complete hydraulic schematics tracing the main pump, main control valve, swing motor, travel motor, and pilot joystick circuits, plus full electrical schematics for hunting shorts through the harness. Inside: a full standard torque section, engine teardown procedures, center joint and cylinder rebuilds, and general maintenance intervals. Sprocket mounting bolts get 6.5 kg-m (47 ft lb); pull the 1/2-inch split flange bolts to 15-18 ft lb before you button up the final drive. No more chasing hydraulic gremlins through forum threads. Bookmarked and keyword-searchable; pull it up on your phone next to the machine and get to work.
