Case 580N, 580SN, 590SN, 580SNWT 2012 Parts Catalog – OEM Factory Breakdown

You ever order a hydraulic cylinder seal kit for a 580SN, get the box open, and find rings that don’t match? That happens when you trust aftermarket catalogs that guess at supersessions. This Case 580N, 580SN, 590SN, 580SNWT 2012 Parts Catalog ends that game. 1734 pages of OEM part numbers, exploded assemblies, and cross-references pulled straight from Case’s Tier 4A program. No guessing, no “maybe this fits” – just the factory breakdown.

Engine Section (Page 2) and Transmission: Critical Assembly Breakdowns

Section 10 covers the engine – page 2 starts the parts listing for short blocks, cylinder heads, gasket sets. Section 21 hits the transmission. If you need a clutch pack or a specific seal for the powershift, you look up the assembly group, find the figure number, and cross-check the part number. The manual gives you the YR/SN ranges so you don’t order a part for a pre-2012 machine when yours is a late build. I’ve seen guys order a main bearing set off a generic list and wind up with the wrong clearance spec. Not here.

Hydraulic Systems: 7 Pages of Cylinder and Valve Data

Section 35 runs seven pages – that’s seven pages of hydraulic cylinder breakdowns, control valve assemblies, and seal kits. The example on page 5 shows a hydraulic cylinder with a 4-3/4 inch stroke, part number 396137A2. You get the fitting, the grease nipple, the piston rod/gland, the seal package – everything broken out by reference number. When a loader arm seal starts leaking, you pull up this section, find your cylinder, and order the exact kit. No wasted downtime.

How to Use This Parts Catalog – General Information

Page 4 explains the ground rules: left and right are from the operator’s seat facing forward. If a common hardware piece isn’t illustrated, it’s listed in the description column. The illustrations show typical assemblies, but you identify parts by function, not just shape. CNH also puts in a note about ongoing improvements – so check the part number against your serial number. That’s how you avoid buying a part that was superseded two years ago. Every pro should read that page before flipping to the index.

Who Needs This Manual? Real-World Use Case

Home garage guys working on a 580N or 590SN backhoe – you need this when the dealer can’t give you a part number over the phone because you don’t have the old one. DIY owners fixing a busted stabilizer leg or a steering cylinder – instead of pulling the whole assembly and driving to the parts counter, you look up the figure, order the part, and have it shipped. For a shop like mine, this catalog sits on the workbench next to the service manual. When a tech says “that seal doesn’t look right,” we grab the Parts Catalog and verify the number. Saves an hour of rework per job.

Source Validity: OEM vs Aftermarket Part Numbers

Aftermarket catalogs renumber parts, omit hardware, and sometimes list obsolete numbers. This is a factory-issued 2012 Parts Catalog from CASE CONSTRUCTION. The print number is MOD-B-TB28/82-C-BU, issued May 2012. Every part number – 396137A2, 402474A, 145221C3 – comes from the OEM drawing system. If you want to cross-reference, you can look up the Automotive Industry Overview, but for Case-specific parts, stick with this catalog. I’ve been turning wrenches for 28 years, and I’ve never seen a third-party catalog that gets the YR/SN splits correct across all 1734 pages. This one does.

FAQ

Does this catalog include service procedures?

No. This is a parts catalog, not a service manual.

How do I find the correct part number for my 580SN’s hydraulic cylinder?

Go to section 35 – Hydraulic Systems. Find the figure that matches your cylinder’s stroke and mounting style. On page 5 you’ll see a cylinder with a 4-3/4 inch stroke (part 396137A2). Your serial number range is printed next to the part. If your 580SN falls between the YR/SN limits listed, that’s your number. If not, check the next figure or look in the alphabetical index for “CYLINDER, HYDRAULIC.” You can also cross-reference the part number against the 55 – Electrical Systems section if the cylinder has a position sensor harness. Always verify the assembly number includes the seal kit reference (like 402476A1) – sometimes the seal package is listed separately and doesn’t come with the cylinder. I’ve had guys order a bare cylinder and then spend two days waiting for the seals.

When you’re elbow-deep in a backhoe rebuild and the part numbers don’t match, you don’t have time to chase aftermarket errors. Access the Factory Manual and get the OEM breakdown on your laptop or print it out for the shop. 1734 pages of verified Case part numbers – engine, transmission, hydraulics, electrical, everything. Stop guessing what fits your 580N or 590SN. Get the parts right the first time.
