Case 580CK Series B Parts Catalog – Factory OEM Parts Breakdown

Look, I’ve chased more bad part numbers through aftermarket catalogs than I care to count. If you’re wrenching on a Case 580CK Series B with shuttle transmission, you need the real OEM data, not some reprint that lost half the detail. This is the genuine Case 580CK Series B Parts Catalog — 380 pages of exploded views, reference numbers, and part numbers that match the factory build. No guesswork about which bushing fits which cylinder. Every fastener, seal, and hydraulic component is laid out with the original part numbers straight from Racine, Wisconsin.

The Automotive Industry Overview might explain why OEM documentation matters, but I’ll save you the theory. When you order a steering cylinder socket assembly (part number 55159), you want the exact part — not a “will-fit” piece that hangs up. This catalog gives you the exploded view on page 4 that shows how the socket, plug, seat, spring, and clamp go together, with the correct quantities per machine.

580CK Series B Parts Catalog: Exploded Views and Part Numbers

Every illustration in this catalog uses reference numbers that tie directly to the parts list. Page 4 shows the rear steering cylinder assembly — reference letter A marks the cylinder, then 28, 29, 30, etc. for each subcomponent. The “REQ’D” column lists exactly how many you need per tractor. If a part is indented, it belongs to the assembly above it. That saves you from ordering five bolts when you only need one.

General Information and Indexes

Flip to page 4 and you’ll find two indexes: an alphabetical index at the front to locate major groups, and a numerical index at the back that cross-references every part number to its page. This is how you find the correct steering cylinder without flipping through 300 pages blind. The revision record log (page 2) shows this catalog replaced the older E1179. If you’re still using that old book, this update includes all changes up to June 1976.

3 Ways This Catalog Prevents Parts Mistakes

First, the serial number tables. Pages 3 and 4 list tractor, transmission, and engine serial number ranges. If you order a part intended for a different build, it won’t fit. Second, the indented description structure — indented parts are sub-components of the assembly above them. Third, the “Number Required” column shows total machine usage, not just per assembly. That means you can buy exactly the right quantity for a full rebuild. Check Automotive Industry Overview for more on serial number traceability.

How to Read the Indented Description

Indented parts throw a lot of beginners. Look at the rear steering cylinder on page 4: the main item is CYLINDER ASSY. (part 55159). Below it, indented items are its sub-assemblies: socket assembly (56208), plug, seat, spring, clamp. The quantity shown for these indented items is the number used within that single cylinder assembly, not for the whole machine. Ignore that and you’ll over-order by a factor of two. The catalog makes that crystal clear in the front notes — read them.

Serial Number Cross-Reference

Page 3 has the tractor model and serial number fields. Every part listing in this catalog references those numbers. If your 580CK Series B has a transmission built after a certain serial break, you get a different clutch pack or hydraulic pump. This catalog marks those breaks. That’s the difference between bolting it together and scrapping it because the shaft splines don’t match. Case 580CK Series B & Model 35 Loader Backhoe Parts Catalog covers the loader and backhoe attachments if you’re doing a full machine teardown.

How do I know if this catalog covers my tractor’s build date?

Check the serial number on the tractor badge against the tables on page 3. The catalog covers all 580CK Series B tractors through the revision date listed.

What exactly does “indented description” mean for ordering parts?

Indented items are part of the preceding assembly. For example, on page 4 the rear steering cylinder assembly (reference A) includes an indented socket assembly (28). The quantity “1” for the socket means one socket per cylinder. But the spring (31) shows quantity “2” — that’s two springs inside that socket. If you order just one spring, the assembly won’t center properly. The indented structure shows that each sub-assembly has its own parts count, and you must sum them across multiple assemblies if the machine uses two cylinders. This level of detail is why aftermarket catalogs cost less but leave you short a spring. You get the complete breakdown here, no reprints or missing pages. For the backhoe and loader attachments, Case 580CK Series B 1979 Parts Catalog – Factory Cylinder Specs gives you the hydraulic cylinder rebuild data you need. And Case 580CK Series B, 35 Loader, 35 Backhoe 1979 Parts Catalog bundles everything together for a one-time checkout.

If you’ve been swapping parts on a 580CK Series B and hoping they fit, stop burning billable hours. This Parts Catalog puts the factory part numbers in your hands — the same numbers the Case dealer uses. You’ll identify what you need, order it once, and have it in the shop ready to install. Access the Factory Manual and keep it on your tablet or workstation. Every bolt, seal, and hose has a number you can trust.
