Part of the Hyundai Repair Manuals.
All 544 pages of this Hyundai R160–R180 series shop manual PDF cover one machine family: the R160LC-9, R160LCD-9, R180LC-9, R180LCD-9, and R180NLC-9 hydraulic excavators. You get full hydraulic schematics tracing the main and pilot circuits through single and combined operation, electrical wiring diagrams with component locations and connector pinouts, and a complete mechatronics section covering mode selection, auto-deceleration, and power boost. Open to the troubleshooting charts when your self-diagnostic system throws a code, or hit the disassembly section for pump, main control valve, swing, and travel device rebuilds. Set boom, arm, and bucket relief pressure to 350 ± 10 kgf/cm2 and fill the hydraulic tank to 124 L before you test. No more chasing wiring faults with a multimeter and a prayer. Bookmarked with a full text layer: search any spec, jump to any section, fix the machine.
