FIAT Allis 31 Parts Catalog

If you’ve ever ordered a part for an old crawler and got the wrong thing because somebody typed a number from a third-party list, you know the pain. That’s why I keep a factory FIAT Allis 31 Parts Catalog on the shelf. This thing is 422 pages of OEM-indexed parts – not some reprint of a reprint. You get the same illustrations and numbers the dealer used. No guessing what “fits if you grind a little” means.

Every time I see a tech wrestling with a seized brake band on a 31, the first thing I check is whether they have the actual part number. This catalog lists the Brake components starting on page 11-4. That’s your brake drum, brake control linkage, brake lock, and the Brake Regulator Valve and Lines on page 11-11. The alphabetical index at the front gets you there fast – no scrolling through PDF pages that aren’t even bookmarked right.

Brake System Parts: Where to Start

The brake section covers everything from the Brake Drum (1G-10) to the Brake Lock (11-13). If you’re rebuilding the final drive on a 31, you need the correct seal numbers for the outboard bearing – listed under Final Drive, pages 1G-6 through 1G-14. Don’t trust aftermarket cross-references. I’ve seen guys ruin a housing because the seal ID was off by 0.010″. Factory parts catalogs don’t have that problem.

Valve Assemblies – Steering, Transmission, and More

Hydraulic control valves are where most DIY guys get burned. The catalog lists the Valve sections for steering (1H-5), transmission (1F-22), and the Brake Regulator Valve and Lines (11-11). Each entry gives you the part number, quantity, and illustration number. You can match the casting numbers on your machine to the exploded view without playing detective.

422 Pages of Indexed Content – How It’s Organized

This manual uses a straight alphabetical index (page A-1). Air cleaner, alternator, batteries, bevel gear shaft – everything is in one list. The Parts Catalog also includes a numerical index (page 2A-4) for quick lookup when you already have a part number. That’s the kind of organization that saves you from ordering three different brake bands only to return two. The page grid cross-reference helps you locate the correct illustration page when the part name is vague.

Before You Order a Part – Check the OEM Source

I’ve watched guys install a steering oil filter from a generic supplier and have the bypass valve stick because the element was a half-inch too short. The catalog spells out exactly which filter element (1H-13, 1H-14) and which transmission oil filter (1F-17) goes where. And for the hydraulic tank, you’ll find the filter element on page 2G-18. No “will it fit” guesswork.

If you’re working on an older machine, especially construction equipment, the Automotive Industry Overview might give you context on why OEM documentation matters – but you don’t need history when you have the part number in hand. The Automotive Industry Overview is interesting reading, but it won’t tell you the correct bolt for the Valve bracket.

Does This Catalog Cover Hydraulic Cylinders?

Yes. The dozer cylinders (2I-3), ripper cylinders (2D-14, G-16), and tilt cylinders (2F-19) are all listed with their mounting hardware and piping. If you need a seal kit, start with the cylinder section – the part number for the complete assembly will lead you to the right repair kit.

FAQ – FIAT Allis 31 Parts Catalog

Is this a repair manual or a parts catalog?

Parts catalog only. It lists part numbers, quantities, and illustrations. No torque specs or repair procedures.

Can I use this to identify parts from a 1970s 31?

Yes. The catalog covers the 31 model without a specific year break. Compare the illustration to your machine – the casting numbers should match the OEM part numbers listed.

How do I look up a part if I only know the name?

Use the alphabetical index at the front. Let’s say you need a “Brake Regulator Valve” – go to page 11-11. The index references every page where that part appears, including any subassemblies.

Can I print pages from this PDF?

Yes. The file is printable. I’d recommend printing the brake section and taking it to the parts counter – it stops the clerk from selling you the wrong item.

Related manuals you might need: FIAT Allis FL5 1989 Parts Catalog – Factory OEM Parts Identification for smaller machines, FIAT Allis FL5 1989 Parts Catalog – Factory OEM Parts Diagrams for visual breakdowns, and FIAT Allis 14B 1975 Parts Catalog – Factory Parts Identification if you work on older track loaders. Each one uses the same factory indexing system.

Don’t waste time with aftermarket cross-reference sheets that get the numbers wrong. Access the Factory Manual and keep it on your tablet or printed in the truck. When you’re ordering brake parts for a 31, you want the number that matches the casting – not a guess from a forum.
