Part of the Hyundai Repair Manuals.
Every one of the 586 pages in this Hyundai R360LC-7 Shop Manual PDF was written to put your crawler excavator back to work. Inside: full hydraulic circuit schematics covering main and pilot circuits, complete electrical wiring diagrams with connector pinouts, and a troubleshooting section that walks the mechatronics self-diagnostic system fault by fault. You also get step-by-step disassembly and assembly procedures for the main pump, control valve, swing and travel devices, plus mounting torque tables for every system on the machine. Check that the bypass relief valve opens at 1.5 kgf/cm2 (21 psi), and confirm the 12V, 160Ah battery is feeding that Delco Remy 28MT starter before you condemn it. 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.
