Part of the Yanmar Repair Manuals.
Need the factory specs for your Yanmar SV100-1A compact excavator? This 719-page service manual walks the machine from the top down: engine, turbocharger, hydraulic pump, control valve, swing motor, travel motor, and undercarriage. Inside: hydraulic circuit schematics with full pressure adjustment procedures, wiring diagrams for the electronic control system, and a dedicated troubleshooting section that separates non-breakdown symptoms from actual failures. You also get exploded views across every major assembly, a torque table covering all critical fasteners, and step-by-step rebuild procedures for both hydraulic and mechanical systems. Torque the swing bearing-to-lower frame bolts to 303.9-323.5 N*m (224.1-238.6 ft*lbf) with Loctite 262, and mark your calendar: rubberized fuel hoses come out at 2,000 hours or two years. Your machine is down and the clock is running. Download now, open it on your tablet, and walk straight to the machine.
