Part of the Hyundai Repair Manuals.
Every one of the 496 pages in this Hyundai R180LC-7 Shop Manual PDF is aimed at one machine: the R180LC-7 crawler excavator, from pump device to undercarriage. Inside: full electrical circuit diagrams with connector pinouts, hydraulic schematics tracing the main and pilot circuits through single and combined operation, and page after page of disassembly and assembly procedures for the pump, main control valve, swing device, and travel motors. You also get component mounting torque tables plus a troubleshooting section that walks the hydraulic, electrical, and mechatronics systems fault by fault. Set the bypass relief valve to open at 1.5 kgf/cm2 (21 psi) and hold axial clearance between the coupling gear and cover to 0.3-0.6 mm during reassembly. Your excavator is dead in the dirt; forum threads won't fix it. Bookmarked, keyword-searchable, and readable on any device you carry into the shop.
