Fiat-allis 580, 580 DT 1986 Parts Catalog – What You Need on the Bench

I’ve spent more hours than I care to count hunting down parts for older equipment. Nothing worse than ordering a bearing by guessing from a worn-out part. The Fiat-allis 580, 580 DT 1986 Parts Catalog kills that guesswork. It’s the factory book – Italian original, printed by Fiat Trattori in 1986. 696 pages of exploded plates, part numbers, and ordering rules straight from the engineering floor. No reprints, no aftermarket translations that mix up thread pitches. This is the same document the dealer’s parts counter used.

Let me walk you through what’s inside and why it matters for anyone wrenching on a 580 or 580 DT.

Ordering Rules: Page 5 and Why It Matters

Page 5 lays out the Norme per le ordinazioni – the ordering rules. You need the tractor model, chassis number, engine type, engine number, and the part order number as shown in the catalog. Skip any of that and you’ll get the wrong piece. I’ve seen guys order a hydraulic pump seal using only the model year and end up with a transmission part. This catalog forces you to cross-reference correctly.

Subgroup Index and Spare Parts Index

Pages 17/1 and 19/1 are your starting points. The subgroup index breaks down every assembly – engine, transmission, hydraulics, chassis. The spare parts index lists every part number with its plate reference. You flip to the plate, find the exploded view, and read the part number next to the callout. No flipping through 600 pages blind.

Does This Catalog Cover Variations?

Yes. There’s a variant list on orange paper (page 13). The 580 and 580 DT are different beasts – the DT is a crawler version. The catalog separates model-specific parts with clear headings and variant codes. You won’t order a wheel part for a track machine.

3 Key Sections Beyond Parts Plates

Toward the back you get the Modifications tables (page 1M) and the Miscellanea section. Bearings, electrical cables, terminals, insulation tubes – all with factory specifications. Need a bearing for the final drive? It’s in the bearing table. Electrical harness repair? Cable sizes and terminal boots are listed. These tables save you from measuring with calipers and guessing.

Why OEM Trumps Aftermarket

Aftermarket catalogs often combine multiple models into one book, drop superseded parts, or use generic drawings. This Fiat-allis catalog is model-specific, printed in five languages (Italian, French, German, English, Spanish), and includes every original part number. The plates are line drawings with exact dimensional references. If the factory says that bolt is M12 x 1.75, that’s what it is.

I’ve compared this to a third-party digital file someone sold me once. The third-party version had a wrong clutch disc thickness. That mistake cost a shop a day of labor. This catalog doesn’t have that problem.

Who Should Use This Manual

DIY owners of a 580 or 580 DT who are tired of ordering blind. Professional mechanics restoring old Fiat-allis equipment. Shop owners who want a precise reference for parts lookup, especially when customers bring in a tractor with a torn-off serial plate. Beginners can use the Use of the catalog guide on page 9 – it explains the iconography and how to read a part number.

Pair this with the Fiat-Allis HD41 Parts Catalog – 370-Page OEM Factory Manual if you’re working on larger dozers. For grader parts, check the Fiat-Allis 12G-B 1979 Parts Catalog – OEM Factory Manual 337 Pages. And for wheel loaders, the Fiat-allis 6G Parts Catalog – OEM Factory Manual 559 Pages covers similar ground.

Some context from the wider Automotive Industry Overview might help understand why OEM documentation standards are so high. But that’s background – the real work is in the catalog.

FAQ

Does this catalog include repair procedures?

No. This is a parts catalog, not a repair manual. It shows exploded views and part numbers. You still need a service manual for removal and installation torque values.

How are the plates organized in the 696 pages?

The plates are grouped by subgroup – engine, transmission, hydraulics, etc. Each plate has a part list on the facing page. You use the subgroup index to find the plate number, then read the part list for quantities and reference numbers. The modification tables at the back (page 1M) update any superseded parts. That’s how you handle a tractor that’s been through field repairs. It’s systematic – once you learn the layout, you can find any part in under two minutes.
