Fiat Powertrain Technologies 415 Parts Catalog – OEM Parts Identification for Tractor Repairs

You are rebuilding a Fiat 415 transmission or chasing a hydraulic leak on a 415 VS. You need the part. You look up the number online, get three different results, none match the bore on your piston. That’s the problem with aftermarket parts lists — they guess, reprint old data, or lump supersessions wrong. I’ve been wrenching long enough to know that when you order a part based on a third‑party catalog, you are gambling with your time. This Fiat Powertrain Technologies 415 Parts Catalog is the factory document. 358 pages, printed on Fiat’s own press in Turin. It tells you exactly which part goes in which model, sub‑group by sub‑group. No guessing, no “close enough.”

Model Coverage: 19 Variants of the 415

Not all 415 tractors are the same. The catalog lists models 01 through 39 — Germany, France, Australia, N, S, GL, GLS, V, VS. Each variant has its own sub‑group validity. Page 3 shows the full list: 01 415 Germania, 02 415 Francia, 03 415 Australia, 04 415 N, 09 415 S, 11 415 S, right through 39 415 VS. That matters because the steering box on a 415 V (vineyard) is different from a 415 GL (gran luce). Skip that check and you install the wrong kingpin. I’ve seen it happen. This catalog forces you to match the model code before you pull a part number.

Sub‑Group Structure: A1.00 Through G2.40

The catalog is organized by functional groups — engine, clutch, gearbox, rear axle, hydraulics, steering, electrical. Each sub‑group has a code like A1.00 (engine block), A2.20 (cylinder head and valves), B2.01 (transmission shafts), F2.02/1 (hydraulic pump). You open to the sub‑group for your system, and the exploded diagram shows every washer, bolt, and seal. There is no generic “pump assembly” number — you get the specific piston pump or gear pump depending on your model. Page 11 (Code No.) explains the numerical coding system. If you have ever ordered a seal that was 0.5 mm too thin and had to tear the axle down again, you understand why this level of detail is not optional.

Audience Fit: Who Needs a Factory Parts Catalog?

If you are a home mechanic trying to keep an old 415 running, or a shop that still sees these tractors at dealer trade‑ins, you need this catalog. The aftermarket parts suppliers will sell you a “universal” hydraulic filter that fits ten different tractors but fits none correctly. With the OEM part number from this catalog, you order the exact filter from the Fiat parts network or cross‑reference to a quality aftermarket brand without guessing the dimensions. I keep a copy of the FIAT Trattori Serie 850 Spare Parts Catalogue on the shelf alongside this one. They are the same format, same clarity. Shop owners who charge by the hour lose money when a tech spends forty minutes verifying a part number from a blurry online scan. This PDF is a clean factory reproduction — you can zoom the diagrams and read the callouts.

Source Validity: OEM Print, Not Aftermarket Copy

Fiat Powertrain Technologies produced this document for its dealer network. The notice on page 2 explicitly states: “Single item numeration method used in this Catalog cannot be used without written consent by Soc. p. Az. FIAT – TURIN.” That is legal language telling you this is the real thing. I have seen aftermarket parts catalogs that copy the illustrations but swap the part numbers to fit their inventory. That gets you a part that looks right but does not meet the original bore tolerance. If you want to trust the numbers, you buy the OEM print. This catalog also includes a five‑language introduction (Italian, French, German, English, Spanish) so that any tech in North America can understand the heading codes. No translation guesswork.

Related Manuals for Fiat Tractors

If you work on the 415’s bigger brothers, check the FIAT Trattori Serie 555 Spare Parts Catalogue 2ª Edizione and the FIAT Trattori Serie 250 Spare Parts Catalogue. Same factory sourcing, same sub‑group numbering logic. All three together give you parts coverage for the most common Fiat tractor lines from the 1960s and 1970s. For general background on tractor engine design, read this Automotive Industry Overview article, and if you need a refresher on diesel combustion fundamentals, the Internal Combustion Engine entry on Wikipedia is solid. But for parts identification, nothing beats the factory book.

Frequently Asked Questions

Does this catalog include engine overhaul torque specs?

No. This is a parts catalog, not a service manual. It gives part numbers, not installation procedures. You want torque values? Buy the factory service manual for the 415.

Are the diagrams clear enough to identify a worn spline coupling?

Yes. The exploded views in the D and F sub‑groups (transmission and hydraulics) show every shaft, spline, and circlip. Zoom the PDF and you can read the part number off the callout. I have done it on a tablet next to the tractor — no issues.

Will this work for a 415 E (étroit)?

It covers model 34 E 415 V (page 3). The narrow‑frame variant is included. Check the sub‑group validity for D1.xx (axle) if you need the narrower hubs.

How do I find a part number for a 1968 415 GL with a casting date stamp?

Start on page 3. Confirm your model code (21 415 GL for Germany, 23 GL for France, 24 GL for Australia). Then go to the relevant sub‑group — for example, A1.00 for engine block, or C1.01 for clutch. Match the illustration to your actual casting. The catalog lists all variations. If you still cannot find it, the numerical code explanation on page 15 (Code No.) helps you decode the part number structure.

I have been burned by aftermarket catalogs too many times. A misordered part costs me at least an hour of diagnostic time and leaves a tractor on the lift while I wait for the correct one. If you want to avoid that, Access the Factory Manual — the original Fiat Powertrain Technologies 415 Parts Catalog — and start ordering the exact parts your tractor needs.
