Fiat-allis 500 Parts Catalog – OEM Factory Manual

You are working on a Fiat-allis 500 and need a replacement bearing or a hydraulic line. You grab an aftermarket parts list, order what you think fits, and three days later the part is wrong. I have seen that cost people billable hours and machine downtime. The Fiat-allis 500 Parts Catalog is the only document Fiat-allis stamped as official. 366 pages of exploded plates and part numbers – no guessing, no aftermarket guesswork. Every number in this catalog came from the same engineers who built the machine. That is the difference between ordering once and ordering twice.

Fiat-allis 500 Parts Catalog: What’s Inside 366 Pages

The catalog is organized by subgroups and plates. You start with the model list on orange paper, page 11, to match your tractor serial number range. From there the subgroup index (page 17/1) points you to the right plate section. Each plate shows an exploded view of the assembly with callout numbers. The spare parts list sits above the plate – part number, description, quantity per machine. There is no separate torque spec section because this is a parts catalog, not a service manual. But for ordering bearings, seals, cables, and structural parts, this is the final word. Automotive Industry Overview covers general supply chain context, but this catalog gives you the exact FIAT part number.

Use of the Catalog: Page 9 Explains It All

Four pages of instructions (pages 6-9) tell you how the numbering system works. In Italian, French, German, English, Spanish – you pick your language. Read the English section on page 9 before you start flipping plates. The catalog uses a single-item numbering method that cannot be reused without FIAT permission. That matters because each part number is unique to the 500 series. If you skip that page, you will misinterpret the index and order the wrong subgroup. Take the two minutes to read it.

5 Sections That Save You from Ordering Wrong Parts

The catalog is split into five major blocks: ordering instructions, model list, subgroup index, numerical index, then the actual spare parts plates. After the plates come the modification tables (page 1M) and miscellaneous tables (bearings page 1T, electrical cables page 3T, terminals and boots page 4T, insulation tubes page 5T). Each miscellaneous table lists standard hardware used across multiple assemblies. If you need a cable boot, go straight to page 4T instead of hunting through every plate. That is the kind of structure that keeps you efficient.

Subgroup Index: How Parts Are Grouped

The subgroup index (page 17/1) breaks the machine into logical groups – engine, transmission, hydraulics, undercarriage, etc. Each subgroup has its own plate range. You find the subgroup number, then flip to the corresponding plate section. The plates are not in serial order by page number; they are grouped by subsystem. That means you must use the index, not thumb through. The numerical index (page 19/1) lets you look up a part number directly if you already have one from a previous repair. Both indices are cross-referenced. If you have a torn bearing retainer and only the old part number, the numerical index gets you to the plate.

Miscellaneous Tables: Bearings, Cables, and Boots

These five tables at the back are gold for restoration work. The bearing table (page 1T) lists every bearing and race used on the 500 – by FIAT part number, dimensions, and application. The electrical cable table (page 3T) gives you the exact length, gauge, and terminal type for each harness section. Terminal boots (page 4T) and insulation tubes (page 5T) are listed with their internal diameters. If you are rewiring a 500 from a melted harness, those tables save you hours of measuring and improvising. No aftermarket catalog gives you this level of detail because they do not have the FIAT design data.

Audience: Who Needs This Factory Parts Catalog

This catalog is for anyone who touches a Fiat-allis 500 – shop mechanics, equipment dealers, restoration guys, even owners who order their own parts. If you have tried to cross-reference a FIAT bearing number to a generic Timken number using internet charts, you know the frustration of wrong dimensions. With this catalog in hand, you match the FIAT number, order from a dealer, and the part lands on your bench with the correct fit. It is also useful for salvage operations. When you are pulling parts off a donor machine, the plates show you exactly how the assembly comes apart and what hardware belongs where.

Source Authenticity: OEM Print vs Aftermarket Scans

I have seen aftermarket parts catalogs that claim to be for the 500 but they miss subgroups, they re-number plates, they drop the miscellaneous tables. This is the original FIAT print – one of the few surviving factory editions that includes the Italian, French, German, English, and Spanish versions in a single volume. The paper is not a reprint; it is a direct scan of the official publication stamped by FIAT Trattori in Turin. The copyright notice on page 2 makes it clear: the numbering system is proprietary. That is your insurance against counterfeit parts. Fiat-Allis HD41 Parts Catalog – 370-Page OEM Factory Manual covers a bigger machine, but the indexing method is identical, so the HD41 catalog is a good companion if you run mixed fleets. Fiat-Allis 12G-B 1979 Parts Catalog – OEM Factory Manual 337 Pages and Fiat-allis 6G Parts Catalog – OEM Factory Manual 559 Pages follow the same FIAT standard.

FAQ

Does this catalog include part prices?

No.

How do I find a part for my specific tractor using this catalog?

Start with the model list on orange paper at page 11. Find your tractor serial number range – the catalog covers tractors from number 500001 onward. Note the model code. Then go to the subgroup index (page 17/1) and locate the assembly you need – for example, the final drive subgroup. The index gives you the plate number. Flip to that plate, find the exploded view, and read the callout number. Cross-reference that number in the spare parts list above the plate. Write down the FIAT part number. Use the numerical index (page 19/1) to verify if you already have an old number. Order from a FIAT dealer using the exact part number from this catalog. If the part appears in the miscellaneous tables (bearings, cables, etc.), you will find it listed there instead of on a plate – check those tables last because they consolidate common hardware.

This is the original FIAT document that should sit next to the service manual on your bench. Access the Factory Manual and stop guessing which bearing fits the pinion shaft.
