Part of the Case IH Operator Manuals.
This 123-page Case IH Farmall 40, 45, 50 Operator Manual (OEM #87398624) puts the factory operating and maintenance procedures for your 12x12 gear transmission tractor right in your hands. You get wiring diagrams for tracing electrical faults, hydraulic controls for the lift and remote circuits, a full safety decal reference, and a lubrication and maintenance section covering every fitting and filter on the machine. Run the Air Cleaner Primary Element cleaning at 100-hour intervals with 30 PSI or less, and drain the fuel filter every 100 hours to keep contaminants out of your injection system. No more flipping through a torn-up shop copy or guessing at your hydraulic oil spec (it's Hy-Tran Ultra, straight from the book). Bookmarked by section so you can jump from Operation straight to Specifications without hunting, this PDF opens on your phone, tablet, or laptop and rides along in the cab.
