Part of the Case IH Repair Manuals.
Diagnose, adjust and rebuild a Case IH Axial-Flow 7250, 8250 or 9250 with the factory service manual, part number 51586252. It covers Tier 4B (final) combines for North America, PIN YJG238001 and above. The coverage runs from the FPT Cursor engines and SCR exhaust treatment through the rotor, cleaning shoe, grain tank and unload drive.
The book gives you the torque tables, capacities, relief pressures and fault code procedures.
The fold-out electrical schematic 51446765 and hydraulic/hydrostatic schematic 51586253 are at the back.
