Part of the Hyundai Repair Manuals.
Every one of the 455 pages in this Hyundai R360LC-3 Shop Manual PDF is aimed at one machine: your R360LC-3 hydraulic excavator, from the pump device to the swing motor. You get complete hydraulic schematics for the main and pilot circuits, factory wiring diagrams with connector layouts and component locations, a full troubleshooting section, and step-by-step disassembly and assembly procedures for the pump, main control valve, swing device, turning joint, and boom, arm and bucket cylinders. Mechatronics coverage too: mode selection, automatic deceleration, and engine control systems. Set the main relief valve at 320 kg/cm2 (4550 psi) and confirm each pump section is putting out 290 l/min at rated speed. No more chasing pilot-pressure gremlins with borrowed specs. Bookmarked with a live text layer; search any spec, jump straight to the fix, and get back on the sticks.
