Fiatallis FR20B 1991 Parts Catalog

You’ve got a Fiatallis FR20B on the bay, and you need the right part number – not a guess from some aftermarket index that’s been photocopied three times. I’ve been wrenching for 28 years, and I can tell you the difference between factory documentation and reprint garbage is the difference between a bolt that torques correctly and one that snaps at 90 ft-lb. This Fiatallis FR20B 1991 Parts Catalog is the real deal: OEM print, 655 pages, covering everything from the engine block to the driver’s seat.

Engine Section A – Parts Breakdown

Section A is the engine. You’re looking for a piston ring set? A head gasket? The exact part number for the injection pump? This section lists every component with exploded illustrations and the Fiatallis factory reference number. No language barriers – the catalog includes English, Italian, French, German, and Spanish descriptions. Need to verify which turbocharger variant your FR20B came with? The alphabetical index on page I-AIG gets you there without flipping through 600 pages. That’s the whole point.

Transmission and Axles: Section B in Detail

Section B covers the mechanical transmission, clutch, shafts, and axles. The FR20B uses a powershift transmission, and the parts breakdown shows every bearing, seal, and gear. If you’re rebuilding the torque converter, you’ll need the factory group numbers from this section – aftermarket manuals often merge parts that are actually different revisions. This catalog keeps them separate, with clear subgroup codes so you order the right shaft seal the first time. You can thank me later.

What Does Section F Cover in the Electrical System?

Section F is the electrical system. Alternator, starter, wiring harness, switches, sensors – all listed with factory part numbers. If you’ve ever chased a parasitic draw through a Chilton’s wiring diagram, you know the pain. This catalog gives you the actual Fiatallis connector and terminal part numbers so you can replace the damaged pigtail instead of splicing wires. Automotive Industry Overview might tell you about standardization, but this manual tells you the specific part. That’s the difference.

3 Reasons the Factory Parts Catalog Beats Aftermarket

First, the part numbers are verified against Fiatallis’s own supersession lists – you get the current revision, not the one that got discontinued in 1993. Second, the exploded-view illustrations show exactly how components fit, which keeps you from ordering a part that looks right but has a different bolt pattern. Third, the catalog includes the “LIST OF CANCELLED PARTS” (Section X) and “LIST OF NEW PARTS” (Section Y), so you can see if your dealer is trying to sell you an obsolete part. That’s real-world value.

Use the Alphabetical Index to Find Parts Fast

The general index on page I-AI starts you with main sections, but the real speed tool is the alphabetical index. Type the part name (in English, Italian, French, German, or Spanish) and you get the subgroup alphanumerical code. Cross-reference to the illustration pages in I-G17 and you’re done. For example, need the hydraulic pump for the FR20B? Look under “Pump, hydraulic” or “Pompa idraulica” – both are in the index. No wasting time.

Source Validity: Original OEM Print from 1991

This isn’t a reprint of a reprint. The file you access is a direct scan of the original Fiatallis factory parts catalog, published in 1991. The hydraulic fittings section (I-F:G) lists every O-ring and adapter straight from the Italian factory specs. I’ve seen aftermarket catalogs that list a $10 part as a $80 assembly because they couldn’t be bothered to index subcomponents. Not here. If you already have a related loader, check the Fiatallis HD-9 1989 Parts Catalog – OEM Factory Specs for that model, or the Fiatallis HD-6A, HD-6AG, HD-6B, HD-6E 1989 Parts Catalog for the HD-6 series. For even larger crawlers, the Fiatallis HD-21 1990 Parts Catalog – Crawler Tractor Parts Manual covers the HD-21. All factory, all accurate.

The catalog also includes a “SUMMARY OF MODIFIED PARTS” (Section W) – when Fiatallis changed a bolt from 10.9 to 12.9 grade, it’s listed here. If you’re rebuilding a machine that’s been through three owners, that section saves you from mixing up hardware.

Everyone who works on these loaders knows the value of a genuine parts catalog. The FR20B is a workhorse, but it’s 30+ years old. Aftermarket databases often drop superseded numbers. This manual gives you the complete chain: original part, supersession, and current replacement. That’s how you keep a machine running without buying parts that don’t fit.

When you’re stuck with a machine down and a parts counter that doesn’t know the difference between a FR20B and a FR10B, this is the document that gets you the right part number. Access the Factory Manual now – it’s the only way to be sure.

Does this manual cover the Fiatallis FR20B engine overhaul?

Yes, but as a parts catalog, it provides exploded views and part numbers for the engine assembly (Section A), not step-by-step repair procedures. For teardown specs, you’d need the service manual. This catalog is for ordering the correct components.

Are part numbers still valid for 2025 orders?

Many are, but Fiatallis was absorbed into CNH. The original numbers are the starting point. Your dealer can cross-reference them. The catalog includes supersession lists (Sections X and Y) to help.

How many pages is it?

655 pages. It’s the full factory document, not an abridged version.

What languages are the part descriptions in?

Every part has base descriptions in English, Italian, French, German, and Spanish. Additional translations are provided for selected terms. The index supports all five languages.
