Fiat-Allis 12G Parts Catalog – OEM Factory Manual, 316 Pages

If you’re tracking down a part for a Fiat-Allis 12G Parts Catalog and relying on a scribbled number from a previous rebuild, you already know the problem. One wrong digit and you’ve got a bucket pin that doesn’t fit or a hydraulic seal that leaks down. That’s what the Fiat-Allis 12G Parts Catalog is for — 316 pages of factory exploded views and part numbers with no shortcuts.

This catalog covers two serial number ranges: S/N 101-UP and S/N 43C01001-UP, and includes the 11R Ripper attachment. It’s the official factory publication, form number 0683934-4, replacing the earlier 0667913-8. That matters because Fiat-Allis updated part numbers and supersessions. If you’re working with a used machine that’s had field retrofits, the older catalog might list a part that’s been superseded twice. This edition catches those changes. The exploded views show every nut, bolt, seal, and bracket in the drivetrain, undercarriage, loader linkage, hydraulic system, and ripper. When a hinge pin is worn and you need the exact diameter and length, you’ll find it here. You won’t have to measure a worn part and guess. The manual gives you the original factory specification. For the steering clutches and brakes, final drives — all of it. And it includes the safety warnings from the factory. Page 2 has a warning about lowering hydraulically controlled equipment before servicing. That’s not a suggestion. it’s a rule that came from someone getting killed.

Fiat-Allis 12G Parts Catalog: What Exploded Views Show You

Every exploded drawing in this catalog is keyed to a numbered list of parts. You see the exact relationship of each component — how the bearing sits inside the final drive housing, which bolts go where, which seal runs on which shaft. This isn’t some aftermarket redraw. These are the same plates the factory used on the assembly line. If you need a part that’s been discontinued, the catalog often shows the superseded number right next to the old one. That alone saves a phone call to a dealer who may not have the history.

Avoid Accidents – Why the Safety Warning on Page 2 Matters

Page 2 carries a warning from the National Safety Council. It says: “Never attempt to clean, oil or adjust a machine while it is in motion.” And a specific note about hydraulically controlled equipment — lower it to the ground before servicing, or support it properly. I’ve seen the result of a loader bucket dropping on a guy who thought the hydraulics would hold. This manual doesn’t assume you know. It spells out what can kill you. Treat that page as required reading before you turn a wrench.

Publications Available – More Than Just Parts

Page 3 lists every official publication for the 12G. Parts catalogs for the injection pump (Roosa Master), operator manuals in English, Spanish, Portuguese, French, and service manuals for the engine, turbocharger, fuel injection system, steering clutches and brakes, final drives, and undercarriage. This parts catalog is the foundation. If you’re rebuilding any of those systems, you need this catalog to order components, then the corresponding service manual for the procedure. It’s all cross-referenced. Use this to get the right part, then use the service manual to install it.

What Serial Numbers Are Covered?

Two ranges: S/N 101-UP and S/N 43C01001-UP. If your machine falls outside these, the 12G models before S/N 1000 may need a different catalog. The front cover lists the loader as serial #43C01001 and up. Verify your serial plate before ordering. The ripper attachment is included — the manual covers the 11R ripper separately. No guesswork.

3 Reasons to Choose OEM Documentation Over Aftermarket

First, accuracy. Aftermarket catalogs often redraw illustrations and drop dimension callouts. This factory PDF has the original line art and notes. Second, supersession history. When Fiat-Allis changed a part, they updated the catalog. A third-party PDF from a random site may have old numbers. Third, safety content. The aftermarket won’t include the accident prevention warnings from page 2. That alone is worth the price of admission. Stick with the source that the dealer uses.

Is this a service manual or just parts?

This is a parts catalog only, not a service manual. For repair procedures, you need the separate service manuals listed on page 3 of this catalog. However, the parts catalog is essential for ordering correct replacement parts. Without it, you risk ordering parts that don’t fit, wasting time and money. The exploded views show exact relationships and part numbers. For engine, transmission, and hydraulic system repairs, refer to the service manuals, including the engine (Form 0645121-5), turbocharger (0677064-8), fuel injection pump (Roosa Master, 0656820-8), and steering clutches and brakes (0659189-5). Those are not in this parts catalog. So use this catalog to order parts, and the service manuals to install them.

How many pages is it?
