Part of the Hyundai Repair Manuals.
All 464 pages of this Hyundai Robex 130LC-3, 130LCM-3 shop manual PDF focus on one job: putting your hydraulic excavator back to factory spec, from pump device to turning joint. You get hydraulic schematics tracing the main and pilot circuits, wiring diagrams with connector pinouts and component locations, and a full troubleshooting section covering the swing, travel, and attachment systems. Disassembly and assembly procedures walk through the pump, swing device, travel device, and main control valve, with tightening torque tables right where you need them. Test the auto idle pressure switch against its 10 kg/cm2 contact rating, and verify charging from the 24V, 60 amp alternator before condemning those twin 12V, 120 Ah batteries. Chasing an electrical fault without the factory diagram is a wasted afternoon. Bookmarked with a live text layer: type the spec, land on the page, get back on the sticks.
