Case 580C 1985 Parts Catalog

If you’re tearing down a 580C backhoe and need to confirm a part number, you don’t have time to chase down a dealer after the job stops. I’ve seen guys order a $400 hydraulic cylinder because they guessed the part number from a blurry online diagram. This Case 580C 1985 Parts Catalog is the cure for that kind of waste. It’s 594 pages of factory-sourced part breakdowns, not some aftermarket reprint that may or may not match the hardware on your machine.

594 Pages of Factory Parts Breakdowns

Every page in this catalog came from the Case Corporation in 1985. The original file name is Case_580C_1985_Parts_Catalog_en-18014012429.pdf – that’s your guarantee it’s the real deal. You get exploded-view illustrations for every major assembly on a 580C Construction King loader backhoe: engine, transmission, hydraulics, backhoe attachment, loader arms, you name it. Each illustration comes with a parts list showing the part number, description, and quantity required. No guesswork.

Alphabetical and Numerical Indexes: How to Navigate

The catalog starts with an Alphabetical Index that points you to major groups and assemblies. At the back there’s a Numerical Index – you look up a part number, and it tells you exactly which page to flip to. I’ve used that Numerical Index a hundred times when a customer walks in with a rusty tag and a shrug. Page references are real, not like some PDF that’s been scanned and reorganized. You get the same layout the Case dealer used.

Why OEM Parts Catalogs Are Worth the Paper

Aftermarket parts catalogs reuse old illustrations, swap part numbers, or leave out hardware that changed mid-production. This one doesn’t. Case printed it in April 1985, and it supersedes the earlier E1283 catalog. The Revision Record Log inside shows you where updates happened – if you keep the catalog current by inserting revised pages, you never order a part that doesn’t fit. I’ve seen a $1,200 mistake because a guy used a third-party PDF that showed the wrong final drive housing. This catalog stops that.

Hardware Specs and Unit Conversions: U.S. and Metric

The catalog lists every bolt, nut, washer, and seal with its exact size. For hardware, they call out the thread type – HHCS (hex head capscrew) in inches or millimeters. Dimensions are given in U.S. units with the metric equivalent right next to them. When you’re ordering a 3/4-10 NC lock nut, you get the part number, not a vague description. That level of detail saves you from buying a box of metric fasteners when your machine needs SAE.

Abbreviations Every Mechanic Should Know

This catalog uses a shorthand that’s standard in the industry. HHCS, NSS (not sold separately), REF (reference), UAR (use as required). If an item is indented under another, it’s a sub-component of that assembly. For example, a track roller assembly includes the nut, washer, seal block, O-ring, and seal – each with its own part number. You don’t order the whole roller when you only need a seal. That’s the difference between a parts catalog and a guessing game.

Revision Record Log: Why You Need to Update

At the front of the catalog there’s a Revision Record Log with spaces to record revision numbers and dates. Case issued revised pages when they changed a part or a supplier. If you don’t insert those pages, you’re working with outdated info. The original catalog warns you: “Failure to keep your catalog up to date will result in confusion and may cause you to order wrong parts.” That’s not a suggestion – that’s money out of your pocket. Keep a binder, put the pages in, and you’ll have a reference that stays accurate for years.

If you need the operating instructions alongside this parts breakdown, check the CASE 580C Loader Backhoe Operator’s Manual 1978 for daily checks and controls. For a more detailed operator reference, the Case 580C Backhoe Loader Operators Manual covers the same machine. And if your 580C has the side-shift backhoe option, the Case 580C Side Shift Backhoe Operators Manual Supplement gives you the extra parts and procedures specific to that setup.

This catalog is a tool, same as a torque wrench. Use it right, and you’ll save hours of cross-referencing. The construction equipment industry has seen enough wasted time – Automotive Industry Overview shows how standardization improves repair efficiency. Automotive Industry Overview may not be your field, but the principle holds: factory data beats guesswork every time.

Does this catalog include torque specs?

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

How do I find a part if I only have the part number?

Go to the Numerical Index at the back of the catalog. It lists every part number in numeric order and tells you the exact page number where that part appears in an illustration and parts list. For example, if you have D35267, you’ll find it under the seal assembly group. The index is thorough – no cross-referencing needed. Make sure your part number is legible; rusted tags can be misleading. If you have the old part number from a superseded revision, you’ll need to check the Revision Record Log for updates.

Are the illustrations clear enough to identify parts?

Yes. They’re line drawings at original print quality – no blurry scans. Each part is called out with a reference number that ties to the parts list. Item 10 in the example shows the face seal assembly broken into individual components (items 6, 7, 8). You can see exactly what’s inside an assembly without taking it apart.

Will this catalog work for a 580C with side-shift backhoe?

It covers the standard backhoe. For the side-shift option, you’ll want the supplement manual – Case 580C Side Shift Backhoe Operators Manual Supplement – which adds the specific parts and illustrations for the side-shift carriage.

This parts catalog isn’t something you read once and shelve. It’s a working document that belongs on your bench next to your impact gun and torque wrench. Access the Factory Manual now and start ordering parts that actually fit.
