Case S580N, 580SN, 580SN WT, 590SN Tractor Loader Backhoe Service Manual (51570597)

The S580N / 580SN / 580SN WT / 590SN is a tractor loader backhoe, so one machine does loader work up front and backhoe trenching out back. This service manual is what I pull when I'm in the field and need factory repair info, not just how to run the machine. People buy it when they're chasing a hydraulic or electrical fault, or tearing into axles, boom, engine, or powershift.

What this manual helps you do

• Diagnose hydraulic problems in the loader and backhoe circuits, then trace them back to valves, pumps, or cylinders
• Check and adjust powershift transmission and axle components after repair or replacement
• Follow step-by-step teardown and rebuild procedures for major components like the engine, steering, and brake systems
• Troubleshoot electrical and wiring issues using proper diagrams for lights, safety switches, and controls
• Set and verify adjustments on linkages, stabilizers, boom, and loader arms after structural or pin/bushing work

Who this is for

This manual fits an excavation contractor, field tech, fleet mechanic, rental yard, or owner-operator who actually wrenches on Case S580N, 580SN, 580SN WT, or 590SN machines. If you mainly want to learn controls, daily checks, or basic capacities, you want the operator's manual instead.

FAQ

Q: Is this a searchable PDF, and can I zoom wiring diagrams?

A: Yes, these manuals are usually supplied as searchable PDF files, and you can zoom in to read wiring and hydraulic schematics clearly.

Q: Does it cover all S580N, 580SN, 580SN WT, and 590SN years and options?

A: It is built around those model designations. For exact serial breaks or odd options, you'd match it against your machine tag or dealer info.

Q: I'm just doing my own repairs, is this the right document?

A: Yes, this is the workshop-level service manual, not a parts book or operator's manual.

Bottom line: If you're repairing or diagnosing an S580N/580SN/580SN WT/590SN, this is the right manual. If you only need how to run it, it's the wrong one.
