Case 580 CK Parts Catalog – OEM Factory Parts

If you are ordering parts for a Case 580 CK tractor built before serial number 8685801, you have two choices: guess which seal fits and hope the counter guy gives you something close, or open the actual factory Parts Catalog and read the correct part number off an exploded view. Guess which one leaves you with a pile of returns and a machine sitting on blocks? I see it every week at my shop — guys bring in a box of wrong gaskets because they went by a generic cross-reference. That stops here.

This is the genuine OEM catalog, G971, issued August 1980 by Case Corporation. It replaces the older catalog F971 and covers every bolt, bearing, hose, and hydraulic seal for the 580 CK wheel tractor. 359 pages of line drawings with callouts tied directly to Case part numbers. No aftermarket interpretation, no “will-fit” guesswork.

Serial Number Cross-Reference

Before you turn a single page, note the serial number break. This catalog applies to tractors with a prior serial number of 8685801. Within the book you will find separate listings for the tractor model, engine serial number, and transmission serial number. Match those numbers against your machine’s data plate. If you skip this step, you are ordering random parts. The catalog even includes a blank revision record log — page 4 — where you can write in superseded numbers as Case issues them. I keep a binder with that log filled in for every job.

Engine Parts Identification

The engine section breaks down the block, cylinder head, fuel system, cooling, and mounting hardware. Each exploded view shows the exact orientation of the fasteners. For a 580 CK, you need to know whether the injector pump uses a different drive coupling after a certain engine serial number. The catalog flags those differences in the description copy below the illustration. When you call a dealer, giving them the part number straight from page 23 (or wherever your section lands) means you get the right part on the first shipment. No returns, no core charges wasted.

Transmission and Drivetrain Components

A common failure on these machines is the shuttle shift seal. The generic aftermarket catalogs often list one seal for all 580 models, but the factory catalog shows three different seal kits depending on the transmission serial number prefix. Inside these 359 pages, each transmission variant has its own exploded spread with torque values for the clutch pack bolts noted in the fastener callout. You won’t find those values in a reprint. Only the OEM keeps the original engineering drawings.

Hydraulic System Breakdown

Hydraulic leaks on a 580 CK can take half a day to trace if you are looking at a blurry copy. This catalog gives you clean, sharp line drawings of the control valve, pump, lift cylinders, and swing cylinder. Each hose is drawn with its routing — no guessing which line goes to the piston end. Page numbers vary by edition, but the section is clearly marked “Hydraulic System.” Use it to match the part number on your old hose before you pull it off. I have had techs take a photo of the catalog page to their parts supplier and come back with a sealed hose that matched the bend radius exactly.

Undercarriage and Frame Parts

The undercarriage section lists all track rollers, idlers, sprockets, and chain — even though the 580 CK is a wheel tractor, the backhoe attachment uses a subframe that bolts to the main frame. That subframe bracket often cracks at the welds. The drawing shows the reinforcement plates and the correct hardened bolts (Grade 8, 5/8-11 threads). Using a standard bolt there gets you a broken bracket at the worst possible moment. The part number for the correct bolt is right in that spread. Don’t trust a hardware store bin.

Source Validity – OEM vs Aftermarket Reprints

This is not a scanned reprint from some third-party reseller. It is the original Case factory publication, G971, printed in 1980 and stored as a high-resolution digital copy. The cover even tells you to trim the dotted line and slide it into the binder spine — a detail that confirms it came from Case’s own printing plant. Aftermarket catalogs often omit the revision log, miss the serial number notes, or redraw the illustrations badly. When a part number has been superseded, the factory catalog shows the old number with a note. A reprint leaves that note out. If you rely on aftermarket documentation, you are working blind.

If you need the Operators Manual for a different variant, check the Case 580 CK Forklift 1995 Operators Manual. Or for a smaller machine, the Case 26 Backhoe Operators Manual covers a different chassis. For hydraulic and undercarriage parts on a larger excavator, the Case CX160B 2007 Parts Catalog – OEM Undercarriage Hydraulics is a solid resource.

Does this Parts Catalog include service procedures like disassembly or torque values?

No. This is a parts identification catalog only. You get exploded views, part numbers, quantities, and some fastener callouts. For repair steps and factory torque specifications, you need the corresponding Service Manual. The parts catalog is meant to be used alongside the service manual to order the correct components before you start wrenching.

How do I confirm my 580 CK serial number falls within the prior SN 8685801 range?

Locate the serial number plate on the left side of the transmission case, near the clutch housing. The tractor model number will read “580 CK” followed by a six- or seven-digit serial. If the number is lower than 8685801 (for example, 8234567), this catalog covers it. Higher numbers require the later catalog F972. The catalog also lists engine and transmission serial numbers separately — check those too. I’ve seen mismatched drivelines where the tractor is pre-8685801 but the engine was swapped from a later machine. The catalog helps you sort that out by showing both component serial ranges.

For a broader understanding of how OEM documentation fits into the heavy-equipment industry, read the Automotive Industry Overview and the related Automotive Industry Overview context on Wikipedia. Bottom line: if you need to keep a 580 CK running without wasting money on wrong parts, you need the factory parts breakdown. Access the Factory Manual now, print the pages you need, and tape them to your toolbox. Your machine will thank you.
