Fiatallis FR 12 B Parts Catalog – OEM Factory Specs

You’ve got a Fiatallis FR 12 B down with a busted air valve. You pull the old part, walk to your phone, call the dealer, and the parts guy asks for a number you don’t have. Or worse, you order from a generic catalog and the threads don’t match. That’s where this 439-page Parts Catalog earns its keep. It’s the factory-issued document, not a reprint or a third-party compilation. Every part number, every reference code, every assembly breakdown came from Fiatallis themselves. The alphabetical index starts on page 1 with everything from “AIR APPLICATION VALVE ASSY” to “BATTERIES & CABLES” – and that’s just the beginning.

Air Application Valve and the Rest of the Air System

Your brake system won’t hold air if you use the wrong seal kit. The catalog lists the AIR APPLICATION VALVE ASSY under reference G423(1) 2M-18. That code tells you exactly which valve assembly fits your FR 12 B. Same for AIR BRAKES LINES (C102(3) 1N-4), AIR DRYER & LINES (G109(1) 2M-11), and the AIR TANKS & LINES (C102(4) 1N-6). Each entry has a figure number and page location. You can cross-check the exploded view on that page to verify the part before you order. No guesswork.

Understanding the Alphabetical Index – How to Navigate 439 Pages

Page 1 lays out the entire manual in a straight alphabetical list. It covers the whole machine: from AIR CLEANER to AXLE & MOUNTING, BATTERIES & CABLES to BOOM PIPING. Every major system gets its own section. For example, if you need the alternator parts, the index points to “ALTERNATOR & MOUNTING” under A119,F303 2L-2. That means you flip to section 2L, page 2. The page numbers are consistent across all language editions – English, Italian, French, German. You can hand this manual to a tech who speaks any of those languages and they’ll find the same part numbers.

3 Reasons to Use OEM Parts Documentation Over Aftermarket

First, the part numbers are verified by Fiatallis, not guessed by a third party. Second, the illustrations match the actual production parts – no re-drawn approximations that shift bolt patterns. Third, you get supersession notes if a part was updated. Aftermarket catalogs often miss those supersessions, so you order an obsolete part. I’ve seen a $5 seal cost a shop an afternoon because the replacement was a different size. Don’t risk it.

Axle and Mounting Sections – Front and Rear

The FR 12 B has two distinct axle assemblies: front (B401 1M-2) and rear (B40G 1M-3). The catalog breaks down every bearing, seal, and fastener in those assemblies. If you’re rebuilding a final drive, you need the correct washer thickness or the preload will be off. The exploded views show the stack-up order. You can count the shims without tearing the machine apart twice. Each axle section includes mounting brackets and hardware – all cross-referenced to the chassis layout.

Batteries, Cables, and Electrical Routing

Electrical gremlins on a loader usually trace back to a corroded cable or wrong terminal. The catalog lists the BATTERIES & CABLES under F301 2H-17. That section gives you the exact cable lengths, terminal types, and battery hold-down parts. Use a generic cable and you’ll fight with routing or get a short to ground. The factory spec for the main battery cable is right there – no measuring needed. For the alternator and mounting, check A119,F303 2L-2. That includes the belt, bracket, and adjusting arm.

Torque specs aren’t in this catalog. You need the service manual for that. But if you’re rebuilding an air application valve (page 1 shows that assembly), you need the correct part numbers for seals, springs, and the valve itself. Without this catalog, you’ll end up with the wrong o-ring, and that means a leaky brake system. I’ve seen it happen. The part number G423(1) 2M-18 is specific to your FR 12 B. Don’t trust a generic cross-reference.

FAQ

Is this the same as a service manual?

No. This is a parts catalog, for ordering parts, not repair procedures.

Can I use this to find torque specs?

Torque specs aren’t listed in a parts catalog. You need the service manual for that. But if you’re rebuilding an air application valve (page 1 shows that assembly), you need the correct part numbers for seals, springs, and the valve itself. Without this catalog, you’ll end up with the wrong o-ring, and that means a leaky brake system. I’ve seen it happen. The part number G423(1) 2M-18 is specific to your FR 12 B. Don’t trust a generic cross-reference.

What languages are included?

English, Italian, French, and German. The part numbers and reference codes are the same across all languages, but the text descriptions are translated. If you’re working on a machine imported from Europe, this helps.

How many pages is it?

439 pages, full alphabetical index from A to Z.
