Part of the Yanmar Repair Manuals.
Need the factory specs for your Yanmar ViO75-A excavator? This 584-page Yanmar ViO75-A service manual PDF (OEM #0BKB3-G75000) puts the complete factory repair data in front of you: engine, hydraulic system, hydraulic components, undercarriage, and electrical circuits. Inside: hydraulic schematics with full fluid routing and pressure adjustment procedures for both piston pumps, wiring diagrams covering every machine circuit, and a troubleshooting section walking engine and hydraulic faults from symptom to fix. Step-by-step rebuild procedures cover the control valve, swing motor, travel motor, and hydraulic pump in sequence. Set each system relief valve to 3555 PSI (24.5 MPa) at 18.5 GPM (70 L/min); torque your track roller bolts to 274.9 to 296.6 ft·lbf (372.7 to 402.1 N·m). Your machine is down. Bookmarked and keyword-searchable: open it on any device and get back to digging.
