Part of the New Holland Repair Manuals.
Got a 2000-model skid steer that quit mid-job? This 644-page New Holland L250, L255 repair manual PDF walks you through both machines, from the Onan gasoline engine in the 250 to the E673 diesel in the 255, plus the hydrostatic drives, axles, and brakes underneath. Inside: full wiring diagrams for the electrical system, hydraulic and hydrostatic schematics, a dedicated troubleshooting section, and hardware torque charts in inch and metric. You also get fuel, cooling, and lubrication procedures, control valve service, and drive chain adjustment. Set hydrostatic charge pressure to 5.5-8.3 bar (80-120 PSI) and confirm main system pressure holds 110-117 bar before you button it up. Your loader earns nothing sitting on jack stands. The PDF is bookmarked with a live text layer; search any spec, open it on any device, and start wrenching.
