Fiatallis 90 C 1981 Parts Catalog – OEM Factory Specs

You have a Fiatallis 90 C on your lot that needs a new hydraulic line or a clutch disc, and you are staring at a pile of parts that might fit – or might not. I have seen too many guys order the wrong part twice because they trusted a third-party parts lookup. This is the Parts Catalog from Fiatallis itself, printed in 1981, 307 pages thick. It gives you the exact OEM part numbers, subgroup breakdowns, and ordering instructions straight from the factory. No translation loss, no generic cross-reference.

If you work on construction equipment for a living, you know that a wrong part means downtime and a pissed-off customer. This catalog eliminates that. Everything from the engine to the electrical system is broken down into plates and lists. The Norme per le ordinazioni (ordering instructions) start on page 5, and the Use of the Catalog section in English begins on page 9. You will not be guessing.

Ordering Parts: Page 5 Instructions

Page 5 of this catalog lays out exactly how to order parts from Fiatallis. It covers the part numbering system, how to reference the model, and what information the dealer needs. If you have ever had a parts counter guy tell you “I need the part number,” this is where that number lives. The catalog is multilingual – Italian, French, English, German, Spanish – so you can hand it to anyone in the shop and they can follow the ordering rules.

Subgroup Index and Numerical Index – Navigation Without Guesswork

The Subgroup index on page 17/1 organizes every major assembly – engine, transmission, hydraulics, undercarriage – into subgroups. Each subgroup has its own set of plates (exploded diagrams) and a corresponding parts list. The Numerical index starting on page 19/1 lists every part number in the catalog in sequence. You can look up a number directly or find it by diagram. Either way, you land on the correct page. This is not a scanned, poorly OCR'd aftermarket mess – this is the real deal from Fiat Trattori S.p.A.

Electrical Cables and Insulation: Pages 3T–7T

Electrical gremlins on a 90 C? The Miscellanea section covers electrical cables (page 3T), cable terminals and boots (page 5T), and insulation tubes (page 7T). These are not generic specs – these are the exact Fiat part numbers for the wire gauge, terminal type, and protective tubing used at the factory. If you are rewiring a harness, pull these pages instead of matching colors by eye. One wrong terminal boot can cause a short that takes out a $400 controller.

Modifications Tables: Page 1M Changes

Fiatallis issued running changes to the 90 C during production. The Modifications tables on page 1M document those changes – what serial number range got updated parts, and what the new part numbers are. If you are restoring a machine or ordering a replacement part, you need to check this section. Ordering an old number when a revised part exists means you get a part that might not fit, and the return shipping is on you. Skip this page and you are throwing money away.

Why OEM Documentation Matters Over Aftermarket

Aftermarket parts catalogs cut corners. They combine multiple model years into one book, they translate part names wrong, and they sometimes omit the revision history entirely. This 1981 Fiatallis Parts Catalog is the original factory document. The part numbers printed here are the ones Fiat used on the assembly line. If the catalog says the part number is 123456, that is the part you order. No cross-referencing, no “equivalent,” no “this might work.” You want to keep a machine running, you use the source. For related manuals, check out the Fiatallis HD-9 1989 Parts Catalog – OEM Factory Specs or the Fiatallis HD-6A, HD-6AG, HD-6B, HD-6E 1989 Parts Catalog if you have other models in the fleet. The Fiatallis HD-21 1990 Parts Catalog – Crawler Tractor Parts Manual covers the bigger iron.

Frequently Asked Questions

Does this catalog include engine overhaul procedures?

No. This is a Parts Catalog, not a service manual. It contains part numbers and exploded views, not step-by-step repair instructions.

How do I use this catalog to order parts for my Fiatallis 90 C?

Start with the Use of the Catalog section on page 9 (English). It explains the subgroup system. Look up the assembly group (e.g., engine) in the Subgroup index on page 17/1, then flip to the corresponding plate. The parts list next to that plate gives the OEM number, quantity, and description. Write that number down, call your Fiatallis dealer, and you are done.

Is the manual available in English?

Yes. The English section begins on page 9 with Use of the Catalog. All plate captions and parts lists are in English as well as Italian, French, German, and Spanish.

How many pages does the catalog have?

307 pages, including the index and miscellanea sections.
