Part of the Case Repair Manuals.
This 886-page Case International Workshop Manual covers the full B and C family lineup: 743, 745, 844, 845, 856XL, 955, 956, 1055, 1056, 1255XL, 1455XL, plus the D-155 through DT402 engine variants. Open it up and you get the basic engine teardown, fuel system and turbocharger work, MFWD final drives, and a full hydraulics section for the 955/1055/56XL machines. Inside you'll find wiring diagrams for the electrical and MFWD control circuits, hydraulic schematics for the lift and auxiliary valve systems, plus a dedicated air conditioning troubleshooting section for the 956, 1056, 1255, and 1455XL. Check nozzle opening pressure at 20-21 MPa and confirm commutator out-of-round stays under 0.03 mm before you reassemble the alternator. No more flipping between three dog-eared manuals trying to match your serial number to the right procedure. Bookmarked by section, so you jump straight to your system, pull it up next to the tractor, and get back under the hood.
