Fiat-allis 6G Parts Catalog – Factory OEM Manual 559 Pages

If you’ve ever ordered a seal kit for your 6G and got the wrong size because some third-party catalog had a misprint, you know the drill. That’s time wasted, machine down, and money burned. This Fiat-allis 6G Parts Catalog is the factory original – not a copy, not a reprint, not a scan with missing pages. It comes straight from Fiat-Allis, carrying form number 73122632. Before you order a single bolt, read the warning on page 1: it tells you to study the operation and maintenance manual before servicing this machine. That’s the kind of safety-first thinking that keeps a loader running and a mechanic out of the hospital.

The Fiat-allis 6G Parts Catalog – 559 Pages of Factory Specs

Every page in this manual is straight from the Fiat-Allis engineering department. You get exploded views of every assembly on the 6G crawler loader: the engine, transmission, final drives, steering clutches, brakes, track frames, shovel, backhoe if equipped, and the ripper. Each illustration is paired with a numbered parts list. Need the part number for a track roller seal? It’s in there, with the exact Fiat-Allis part number – not a cross-reference from some aftermarket house that might be wrong. The manual covers serial number breaks: S/N 101-UP and S/N 37A22251-UP, plus a separate publication list for loaders prior to S/N 13322 and from S/N 13322 up. That level of detail saves you from ordering a part that won’t fit.

What Serial Numbers Does This Parts Catalog Cover?

Look at page 4. The model identification section shows serial number breaks. This catalog covers 6G loaders with S/N 101-UP and S/N 37A22251-UP. There’s also a separate listing for machines prior to S/N 13322 – that publication list (pages 2 and 3) tells you which form numbers go with which serial range. For example, injection pump parts use form 70696878; the service manual set uses 70689643. If you own a machine with a serial number in between, check the table before ordering. Getting the wrong form number means wrong parts – and a loader that sits.

Check the Publication List Before Ordering Parts

Pages 2 and 3 are your roadmap. They list every available publication for the 6G: parts catalogs, operators manuals, service manuals for engine, clutch, fuel injection, shovel, steering, final drives, tracks, transmission. Each has its own form number. The parts catalog itself is form 73122632 – the one you’re looking at. Notice that for the backhoe attachment, the parts catalog changed at S/N 15791-up (form 70690215). If you have an older machine, that form number is different. Don’t assume one catalog covers all attachments. That’s how you end up with a box of wrong parts and a call to your dealer asking for a return.

Parts Identification: How the Manual Is Organized

Open to any page – say page 26 – and you’ll see a large exploded view of a subassembly, with reference numbers pointing to each component. Below the illustration is a table listing the reference number, the Fiat-Allis part number, the quantity used per assembly, and a description. Many part descriptions include critical notes like “LH” or “RH.” When you’re rebuilding a final drive, that left-hand seal is not the same as the right-hand one. The manual makes that clear. Torque specs? Those are in the service manual, not the parts catalog – but the parts catalog gives you the exact fastener part number so you can order the right bolt. Never reuse a torque-to-yield bolt on a loader; the parts catalog tells you which ones are single-use.

3 Reasons the OEM Manual Beats Aftermarket Copies

First, the illustrations are scanned from the original metal plates – not a photocopy of a photocopy. Aftermarket catalogs often redraw parts and miss key details like chamfers or thread lengths. Second, the part numbers are authentic. I’ve seen aftermarket catalogs list a “universal” seal that fits five different models – it never fits right. Here, each part number is specific to the 6G. Third, the serial number breaks are accurate. Fiat-Allis made running changes; the OEM catalog documents them. If you rely on a generic parts list, you’ll be swapping out parts twice. Fiat-Allis HD41 Parts Catalog – 370-Page OEM Factory Manual covers a bigger machine, but the same principles apply. Fiat-Allis 12G-B 1979 Parts Catalog – OEM Factory Manual 337 Pages and FIAT-ALLIS 12G Crawler Loader Parts Catalog are also factory-original and follow the same layout as this one.

Who Needs This Parts Catalog?

If you maintain a 6G in your own shop, you need this. Home garage guys – yes, you. Dealers have access to the electronic parts system, but if you’re a one-man operation, you can’t log into the dealer portal. This paper‑based (PDF) catalog gives you the same information. Professional shop owners: put a copy on every technician’s tablet. When the boss asks why a job took three hours instead of one because you ordered the wrong track pin, hand him this manual. It eliminates guesswork. For a deeper dive into the automotive industry, check out Automotive Industry Overview – but this Fiat-Allis manual is more specific to construction equipment. For general industry context, Automotive Industry Overview gives a background on how OEMs standardize parts.

Can I use this parts catalog for a 6G with a backhoe attachment?

Yes, but check the serial number. The backhoe parts catalog has a separate form number (70690215 for S/N 15791-up). This main parts catalog (73122632) covers the base loader only. For backhoe parts, you need the specific backhoe parts manual.

Does it include torque specs?

No. This is a parts catalog, not a service manual. Torque values are in the service manual (form 70677543 for earlier machines, 70689643 for later).

The bottom line: if you’re tearing into a 6G, you need the right parts in hand. This 559-page factory catalog gives you the part numbers, quantities, and illustrations to order exactly what fits.
