Part of the Case IH Repair Manuals.
Within the hour you could be splitting the hydrostatic pump on your 1460, and this Case IH 1440, 1460, 1480 service manual PDF puts the Eaton teardown in front of you: 864 pages of factory service data, OEM GSS-1479-B, covering all three Axial-Flow combines. The hydrostatic drive gets the longest treatment in the book, from principles through troubleshooting to pump and motor rebuilds, and hydraulic schematics trace the header lift and automatic header control circuits valve by valve. Wiring diagrams for the cab, shaft speed monitor, and air conditioning close out the electrical section. Torque the pulley retaining nut on the feeder jackshaft to 185 to 250 ft. lbs. and the rotor reluctance pickup lock nut to 35 to 40 ft. lbs., straight from the spec tables. Guess wrong on a rotor rebuild and the second teardown costs you a harvest day. Bookmarked and text searchable, it goes wherever the combine sits, shop or field edge.
