This is a genuine Case IH factory Service Manual set, primary publication numbers 6-14440 and 6-13290, for the STX275, STX325, STX375, STX425, STX450, and STX500 Steiger tractors, in both Wheel and Quadtrac configurations. The Steiger STX line is Case IH's flagship articulated 4WD tractor family, built at the former Steiger Tractor plant in Fargo, North Dakota, with 405-682 hp engines ranging from 8.7 to 12.9 liters.
Because the STX275/325 and STX375-450 sub-ranges use different steering control units, transmission removal procedures, and starter motors (Nippondenso vs. Delco Remy), Case IH's own manual separates these procedures explicitly by model range at every relevant section rather than presenting one generic procedure - exactly what a technician needs to avoid applying the wrong specification to the wrong machine.
