Fiat Powertrain Technologies 415 DT Parts Catalog

If you are trying to track down a part number for a 415 DT tractor and you are staring at a third-party parts catalog that doesn’t match what you pulled off the machine, you are not alone. I have seen too many hours wasted on wrong cross-references. This is the real thing: Fiat Powertrain Technologies 415 DT Parts Catalog, the OEM supplement that Fiat printed for dealers and shops. 348 pages of factory-issued parts breakdowns, in four languages, with the original Fiat part numbers. No aftermarket guesswork.

What This Supplement Adds to the Base 415 Catalog

This document is explicitly labeled “SUPPLEMENT TO THE 415 SPARE PARTS CATALOG”. It does not repeat the entire base catalog – it covers updates and new sub-assemblies specific to the 415 DT model. Page 2 spells out that you need to refer to the base 415 catalog for general usage instructions. The supplement uses the same numbering system: each part is identified by a Fiat code, and the tables show modification numbers (e.g., “modifica 935”) to track production changes. If your 415 DT has a serial number before or after a certain modification, you need to check the validity tables in this supplement to get the right part.

How to Navigate the 415 DT Supplement

Flip to the orange model list to locate the subgroup index that applies to your tractor. Then cross-reference the “Validità dei sottogruppi” (group validity) on page 5 to confirm the subgroup is correct for your machine. Every table includes modification columns – never skip those. I have seen guys order a hydraulic pump seal using the base catalog number only to find out the DT uses a different seal after serial number XXXXX. This supplement catches those changes.

3 Reasons You Need the Factory Parts Catalog

1. Part number accuracy. Aftermarket catalogs often merge multiple models into one generic listing. This supplement is model-specific: 415 DT only. 2. Modification tracking. When Fiat issued a change (like a new cylinder head gasket), they updated the parts list with a modification number. You see it in the column: “Colonna ‘Modifica'”. Without that, you risk ordering a part that won’t fit. 3. Language options. Italian, English, French, German, Spanish. If English is your language, page 8 gives the direct translation of all warnings and instructions. No translation app needed.

Does This Catalog Cover the Complete Engine?

It covers the engine as part of the powertrain – after all, this is from Fiat Powertrain Technologies. The Internal Combustion Engine section includes all major internal components: pistons, rings, liners, bearings, gaskets. But remember, it’s a parts catalog, not a service manual. You will not find torque specs or repair procedures here. For that you need the separate service manual. What you do get: exploded diagrams with every nut and bolt labeled, and the exact Fiat part number to order. Need the charge pressure? Not here – that’s in the service manual. But you will find the part number for the oil pump relief valve.

Source Authenticity: OEM Fiat, Not a Photocopy

This is a genuine Fiat publication, printed by Fiat Divisione Meccanizzazione Agricola in Turin. Copyright Soc. p. Az. FIAT – TORINO. The page headers and footers show the original printing numbers and distribution codes. The Automotive Industry Overview of parts documentation has shifted to digital, but this PDF is a direct scan of the factory-issued booklet. No reprints, no third-party alterations. If you are restoring a 415 DT or keeping a working tractor in the field, having the OEM parts breakdown is the difference between getting the job done in one order and spending two weeks returning wrong parts.

Real-World Use: Finding a Hydraulic Pump Seal

You need a shaft seal for the hydraulic pump on your 415 DT. Open the supplement, go to the orange model list, find the hydraulic subgroup (likely index H or similar). Check the validity table to see if your tractor serial number falls within the range listed. The diagram shows the seal with a callout number. Cross that number to the parts table: Fiat part number 1234567. Order that. Done. No cross-referencing to a generic seal catalog. No guessing if the aftermarket seal has the same shore hardness. You get the factory exact part.

What is the difference between this supplement and the base 415 catalog?

The supplement contains updates and model-specific parts for the 415 DT that were added after the base catalog was printed. You need both the base catalog and this supplement for complete coverage.

Can I use this catalog to order parts from any dealer?

Yes – Fiat part numbers are universal across dealers. Provide the number from this catalog and any dealer can order it. But verify the modification code on your machine matches the table.

Does the catalog include torque specs?

No. This is a parts catalog only. Torque specifications are in the service manual. Do not guess torque based on diagrams.

How do I find a specific part number quickly?

Use the orange model list to identify the subgroup index, then locate the diagram that matches your machine. Cross-reference the callout number with the parts table.

Stop wasting time with aftermarket catalogs that merge years and models together. Access the Factory Manual – the genuine Fiat Powertrain Technologies 415 DT Parts Catalog – and get the right part number every time.
