Case 35 Loader, 580CK Series B Tractor 1980 Parts Catalog

You’ve got a Case 35 Loader, 580CK Series B Tractor 1980 Parts Catalog on the table. What’s that worth? If you’ve ever ordered a part that didn’t fit because the parts guy read the wrong serial number, you already know. I’ve seen guys throw two days of labor down the drain because they grabbed a seal from a “compatible” aftermarket kit. This catalog kills that gamble. It’s the original JI Case print – no reprint, no scan of a scan. 102 pages of factory part numbers, exploded views, and revision records that show you exactly what went on the machine when it left the plant.

General Information: What This Catalog Covers

Page 5 lays out the general information and indexing system. You get an alphabetical index at the front to find major groups and assemblies, and a numerical index at the back that ties part numbers to the page they live on. That’s not fancy – it’s functional. The catalog covers the Model 35 Loader and Backhoe mounted on the 580CK Series B Tractor. Engine and machine serial numbers are referenced in the ordering instructions, so you need to know your unit’s serial number before you start flipping pages. Skimp on that step and you’ll be ordering a track roller for a machine that never had one.

Illustrations and Exploded Views – No Guesswork

Every part is shown in an exploded view. The illustration numbers match the reference numbers in the parts list. You get the part number, description, and quantity required. For a loader bucket cylinder or a backhoe swing frame, you can see exactly how the bushings, seals, and pins stack up. That matters when you’re rebuilding a hydraulic cylinder and need to know if the rod seal comes with a backup ring or not. The illustrations are black-and-white line drawings, but they’re clear enough that even a beginner can tell which bolt goes where.

Indented Description: How Assembly Parts Are Listed

Indented parts in the description list are part of the preceding assembly or subassembly. The quantity shown for indented items is the number used in that specific assembly, not the whole machine. So if you’re ordering the complete backhoe frame, you’ll see the main assembly at the left margin and the sub-components indented underneath. This is where DIY guys get into trouble – they ignore the indentation and double-count parts. Pay attention to the indents and you won’t end up with five extra bushings you can’t return.

Orders and Changes: Using the Revision System

This catalog came with revision sheets. Page 2 shows Revision 2 dated August 1980, and page 3 shows Revision 1 dated June 1980. The revision instructions tell you to remove and discard old pages, insert new ones, and keep the revision cover sheet as a record. If you get a catalog that’s missing those revision inserts, you’re working with outdated information. The original Form No. G1151 superseded the earlier F1151 catalog – that’s noted on page 4. Failure to insert revision pages leads to confusion. That’s not my opinion; it’s printed on page 5 of the catalog itself.

Why OEM Parts Catalogs Beat Aftermarket Lists

Aftermarket parts catalogs use generic part numbers and illustrations that are “close enough.” Close enough gets you a boom cylinder that binds because the port orientation is off by 10 degrees. This Case catalog uses original Case part numbers like 27948 for the track roller assembly and 131-737 for the lock nut. You cross-reference that with the actual machine serial number and you get the exact part that Case engineers spec’d. If you’re working on a 580CK Series B that has been through three owners and a flood, you need the OEM number to sort out what’s been swapped. Automotive Industry Overview covers the broader context of OEM vs. aftermarket, but for your loader, stick to this catalog.

3 Reasons to Keep This Catalog on Your Workbench

1. Serial-number-specific ordering. The ordering section on page 5 demands machine and engine serial numbers. That’s your mainline to getting the right part the first time.
2. Revision history included. The revision log on page 4 shows every update from April 1979 through August 1980. You can verify if your catalog has all the changes.
3. Exploded views for assembly. When you tear down a backhoe swing frame, you need to know the order of shims and spacers. The illustration shows it; the indented parts list confirms quantities.

FAQ – Case 35 Loader / 580CK Series B Parts Catalog

How many pages are in this catalog?

102 pages, including revision inserts and the revision log.

What years does this catalog cover?

The original print date is April 1979 (Form G1151). Two official revisions were issued – June 1980 (Revision 1) and August 1980 (Revision 2). The catalog supersedes the earlier F1151 catalog. If you have a machine built in late 1979 or 1980, you need at least the base catalog plus Revision 1 to get all current parts.

Can I use this catalog to diagnose a hydraulic problem?

This is a parts catalog, not a service manual. It won’t tell you how to test pressure or adjust relief valves. What it will do is give you the correct part numbers for seals, spools, and hoses so you don’t order the wrong component. For diagnostic procedures, you’d need the separate Case service manual for the 580CK Series B.

My machine has a specialty attachment like a quick-coupler. Is that covered?

The catalog covers the Model 35 Loader and Backhoe as sold by Case. Factory options like quick-couplers, auxiliary hydraulics, or cab packages may appear in the illustrations if they were part of the standard lineup. Non-factory attachments are not listed. Check the index for “coupler” or “hydraulic control” – if it’s not there, you’ll need to source the attachment maker’s own parts list.
