Case 580K 1990 Parts Catalog – Factory Parts Breakdown

I’ve lost count of how many times I’ve seen a guy order the wrong injector line because he was guessing from a blurry aftermarket diagram. That’s why I keep a factory Case 580K 1990 Parts Catalog on the bench. 715 pages of exploded views, reference numbers, and part numbers that match what Case stamped on the casting. No guesswork. No “this looks close”. You get the exact part that fits the PIN range JJG0020000 and after. If you’re pulling a 580K apart, you want the book that came from the same plant as the machine.

Engine Section: Finding the Right Block Parts

The Engine chapter (Section 2) is where you’ll spend most of your time if you’re doing a rebuild or chasing a coolant leak. Every gasket, piston ring, and head bolt is listed with the factory part number. Case used a specific block configuration on the 580K after PIN JJG0020000 – this catalog covers that exact run. So when you need a cylinder head gasket, you flip to the exploded view, note the reference number, and look it up on the facing page. No need to cross-reference six different web sites. The same applies to the Fuel System (Section 3): injection pump, fuel lines, lift pump – all drawn in relation to each other so you can see how the return line routes before you pull the old one.

You’ll also find a PIN and serial number location guide on page 1-2. Write those numbers down before you order anything. The catalog tells you exactly where to look (left-hand door, engine block, transaxle). I’ve had guys skip this step and buy a part for a different build batch – then they’re stuck waiting on the right one.

Fuel System: Injectors and Lines – Don’t Mix Them Up

The Fuel chapter uses the same exploded-view format as the rest of the book. You get the injector nozzle part number, the return line O‑ring, the fuel filter head assembly. Case used different injection pumps depending on the engine serial range – this catalog flags those splits. Look for the “UAR” (Use As Required) note in the quantity column: that means the number of clamps or seals depends on your specific build. Don’t assume one size fits all. If you’re retrofitting a later engine, you need to check the PIN range first. Case 580K Loader Backhoe 1995 Operators Manual gives you the operating specs, but for parts, this catalog is the only source I trust.

Electrical: Tracing the Wiring Without Burning Stuff

Section 4 covers the Electrical system. Alternator, starter, glow plugs, harness connectors – all drawn with the part numbers for the connectors themselves. If you’ve ever tried to find a three‑pin connector for a Case tractor on a generic parts site, you know the frustration. This catalog lists the actual Case part number for the housing and the terminals separately. Page numbers? Don’t need to memorize them – the Numerical Index (Section 10) lists every part number in alpha/numeric order and tells you exactly which page and reference number to look at. That index alone saves you an hour of leafing through pages. For related electrical diagnostics, the CASE 580K Loader Backhoe Operators Manual 1995 covers daily checks, but this catalog is where you find the replacement lamp assembly.

Can You Use This on Your 580K?

If your machine’s PIN is JJG0016163 through JJG0016166, JJG0018899 through JJG0018900, or JJG0020000 and after – yes. This catalog was issued in September 1990 and replaces Bur 8-5580. The cover explicitly says “P.I.N. JJG0020000 & After”, but the inside covers the earlier ranges too. I’ve seen these used on 580K Loader Backhoes from the late‑80s to early‑90s. The chassis, hydraulics, brakes, and power train sections (6, 7, 8, and 9) all follow the same format. If you’re working on a 580K, this is the parts bible. Case 580K Construction King Parts Catalog is the matching manual for the same machine – make sure you have the right PIN range.

Parts Catalogs vs Service Manuals: Know the Difference

This is a parts catalog, not a service manual. It won’t tell you how to torque the head bolts or bleed the fuel system. What it does give you is the factory part number for every fastener, seal, and bracket. If you pair this catalog with a genuine service manual, you’ve got the complete picture. The Automotive Industry Overview on Wikipedia is a good background read, but for real workbench use, nothing beats the OEM documentation. Automotive Industry Overview is fine for history – this catalog is for getting the job done.

What the Numerical Index Does for You

Section 10, the Numerical Index, takes up the last 150‑plus pages. Every part number from all the previous sections is listed alphabetically, with the page and reference number where it appears. If you have a part in hand with a stamped number, you start there. No flipping through sections hoping to spot it. This is especially handy when you’re working on a machine that’s been swapped around – you can identify a part from another model quickly. The index tells you if it’s a hydraulic fitting, a wiring terminal, or a cab bolt. One part number, one lookup.

Does this catalog cover the transmission rebuild?

No. This is a parts catalog, so it lists the gears, seals, and bearings with part numbers, but no assembly procedures. For rebuild steps, you need the service manual.

How do I know if my PIN is covered?

Check the tag below the left‑hand door on the chassis. If your PIN falls in ranges JJG0016163–JJG0016166, JJG0018899–JJG0018900, or JJG0020000 and after, you’re covered. The catalog also includes a space to record your serial numbers on page 1-2. If your machine is outside those ranges, you need the earlier catalog (Bur 8-5580). Fire up your browser and cross-reference your PIN before you buy.

I keep this catalog in a three‑ring binder on the toolbox shelf. When a part arrives and the box doesn’t match what I ordered, I go straight to the Numerical Index and verify the number against the exploded view. That routine has caught two wrong shipments in the last year alone. If you work on a 580K, you need this book. Access the Factory Manual and get the right parts the first time.
