Part of the Hyundai Repair Manuals.
Need factory answers for your Hyundai R130W-3 Wheel Excavator? This 669-page Hyundai R130W-3 service manual PDF covers the machine from main pump to bucket cylinder, straight from the factory. Inside: full electrical circuit diagrams, hydraulic schematics with complete circuit routing, and a troubleshooting section that walks you from symptom to fix on both hydraulic and mechanical systems. You also get teardown and rebuild procedures for the pump device, swing motor, travel motor, transmission, axles, and every cylinder on the work equipment. Main relief valve pressure is 320 kg/cm² and engine oil capacity is 10 liters, both straight from the factory spec tables. No more chasing wiring faults with a multimeter and a prayer. Bookmarked and keyword-searchable; jump straight to the spec, then get back under the machine.
