Case 580CK Series B, 35 Loader, 35 Backhoe Parts Catalog – 468 Pages

Description

Case 580CK Series B, 35 Loader, 35 Backhoe Parts Catalog – 468 pages of factory part numbers, exploded views, and revision updates. No aftermarket speculation. If you’ve ever tried ordering a hydraulic fitting for a 580CK Series B and received the wrong thread pitch, you know what I’m talking about. I’ve been turning wrenches for 28 years and I still refuse to touch a parts lookup without the OEM catalog in front of me. This is the original Case printing – not a scan, not a reprint – with the revision pages that the factory sent out to update parts departments. That matters when a part supercedes because of a design change.

Let’s be clear: this is a parts catalog, not a repair manual. It tells you exactly which part number goes where, not how to replace it. But without the right part number, you’re buying twice. I’ve seen guys order a boom pin based on a generic cross-reference and end up with a pin that’s 0.020″ undersize. That’s a sloppy fit in the bushing, and you’ll be chasing slack in the loader arms within 50 hours. The factory catalog gives you the actual Case part number, the supersession chain, and the exact quantity needed per assembly.

Parts Breakdown for the 35 Loader and Backhoe

The catalog is organized by assembly groups. You’ll find the 35 Loader’s subframe, lift arms, bucket linkage, and hydraulic cylinders laid out in exploded views. Each part is keyed to a number in the illustration. Opposite that number is the Case part number, description, and notes like “includes seal kit” or “order by serial number break.” For the 35 Backhoe, you get the swing frame, dipper stick, bucket cylinders, stabilizers, and all the pins and bushings. Revision page 5-6 in the original update list shows that the backhoe boom cylinder seal kit changed in early 1976 – raw data like that keeps you from ordering obsolete stock.

Why Factory Parts Catalogs Outlast Aftermarket Copies

Aftermarket parts catalogs are assembled from old microfiche scans. They often miss pages, have wrong part numbers, and never include the revision inserts. This catalog has a set of revision pages dated February 1976 that the factory mailed to dealers. Those revisions correct part numbers, add new assemblies, and remove discontinued parts. If you rely on a third-party PDF, you’re working with frozen data. The OEM catalog is dynamic – you get the complete historical record of what changed and when. That’s the difference between ordering a part that fits and ordering a part that doesn’t.

What This 468-Page Catalog Actually Contains

468 numbered pages plus the revision page inserts listed in the front matter. The table of contents covers the following major groups: Tractor (common chassis components), Loader (35 Loader specific), and Backhoe (35 Backhoe specific). Within each group you have sections like “Hydraulic Cylinders,” “Control Valves,” “Bucket and Teeth,” “Pins and Bushings,” “Seals and O-Rings.” Every page has a page number and a revision indicator. The index at the back lets you look up any part by name. For example, “pin, pivot, loader” will take you to the loader arm assembly page. No flipping through random sections.

Three Systems You’ll Reference Most

1. Hydraulic Cylinders – The 35 Loader uses a pair of lift cylinders and a bucket cylinder. The 35 Backhoe adds swing, boom, dipper, and stabilizer cylinders. Each cylinder has its own exploded view with seal part numbers. Don’t guess which O-ring goes where. The catalog tells you the exact Case seal kit number.
2. Loader Bucket and Teeth – Bucket edge, cutting edge, teeth, and shrouds. Part numbers vary by bucket width and tooth type. The catalog lists optional tooth styles.
3. Backhoe Swing Frame and Pins – The swing pivot has a pair of bushings and a pin that wears faster than anything else. The catalog shows the pin diameter and length. I’ve seen guys order a generic pin that’s 1/4″ too short – that’s a safety hazard if the retaining clip doesn’t engage.

Get the Right Part Numbers – No Guessing

Every part number in this catalog is the original Case number. If a part has been superseded, the catalog notes the replacement number in the revision pages. For instance, the original bucket tooth part number changed on certain serial number ranges. The revision page shows the new number and the old number it replaces. Without that, you’d order an obsolete part and the dealer would tell you it’s no longer available. The catalog also includes the quantity required per assembly. You won’t order one seal when you need two.

If you’re working on the base tractor as well, I recommend picking up the companion parts catalog for the 580CK Series B chassis. Check out Case 580CK Series B Tractor Parts Catalog F1179 for the engine, transmission, and driveline parts. For loader-specific updates after 1977, get Case 35 Loader 580CK Series B 1980 Parts Catalog – OEM Specs. And if you’re rebuilding cylinders, Case 580CK Series B 1979 Parts Catalog – Factory Cylinder Specs has the bore and stroke numbers you need to order seal kits.

Looking for broader context on why OEM documentation matters? Automotive Industry Overview might give you history, but it won’t give you a part number. Automotive Industry Overview is fine for background reading, not for ordering parts.

Stick with factory data.

Frequently Asked Questions

Does this catalog include torque specs or repair procedures?

No. This is a parts catalog only. It contains part numbers, illustrations, and quantity information. For torque specs and disassembly procedures, you need the corresponding service manual for the 580CK Series B.

How do the revision pages work? Are they included in this copy?

Yes, the digital copy includes the original revision page set issued February 1976. These are the pages that Case Parts Departments inserted into their loose-leaf catalogs to keep them current. The revision set lists all the pages that were updated, and the PDF includes those corrected pages in place. So you’re getting the catalog as a factory dealer would have had it after the first revision. If later revisions were published, you’d need to source those separately, but this is the most common revision for the 1974-1976 production run.

Bottom line: if you’re ordering parts for a Case 580CK Series B with a 35 Loader and 35 Backhoe, don’t trust a third-party list. Get the factory parts catalog – 468 pages of OEM part numbers, revision history, and exploded views that eliminate the guesswork. Access the Factory Manual and get the right part the first time.
