Part of the Case IH Repair Manuals.
All 667 pages of this Case IH Farmall 80JXM / Farmall 90JXM Service Manual (OEM #47866581) are built around one goal: giving you factory-level control over every system on your Farmall® tractor. Inside, you get full wiring diagrams covering harnesses, connectors, alternator, and warning indicators, plus hydraulic schematics tracing the fixed displacement pump, remote control valves, and main lift circuit from reservoir to cylinder. The transmission section alone spans mechanical, power shuttle, creeper, and dropbox configurations — with exploded views and step-by-step rebuild procedures throughout. Set the hydraulic pump drive gear nut to 30 N·m and confirm your fixed displacement pump delivers at least 11 L/min at 166 bar before signing off on a rebuild. Your machine is down and the clock is running. Pull up the bookmarked PDF on your tablet, jump straight to the section you need, and get to work.
