Fiatallis 300 Parts Catalog – Factory OEM Documentation for the Workbench

If you’ve ever wasted a morning cross-referencing aftermarket parts numbers only to find they don’t match the bearing you’re pressing into a final drive, you know the cost of bad documentation. This Fiatallis 300 Parts Catalog is the factory-issued book – 320 pages, printed by Fiat in 1971, and built to be the single source for every bolt, seal, and electrical cable on these machines. It’s not a reprint; it’s the original file turned into a PDF with all five languages: Italian, French, German, English, Spanish. You get the same exploded-view plates and part lists that the dealer would have used when the 300 was new.

Ordering Parts the Factory Way

Page 5 covers the ordering process – how to specify the correct part number, what information the supplier needs, and the format of the catalog’s number system. Skip that page and you’ll probably order the wrong piston ring or gasket set. The catalog assumes you read the instructions. Following these rules means the part you order will match the machine’s build date and modification level. No phone calls to the dealer asking “is this the one with the longer stud?”

Model List on Orange Paper – Why That Matters

Starting on page 11, the model list appears on orange-colored paper within the original print. This was deliberate: orange pages flag configuration differences. The catalog covers all variants of the 300 series – engine, transmission, hydraulic options. You check the model list first to see which subgroup indexes apply to your specific unit. Ignore this step and you’ll be looking at parts that don’t fit. Every 300 is not the same.

320 Pages of Exploded View Plates

The bulk of the catalog is the spare parts plates and their accompanying part lists. Each plate shows an assembly – clutch, final drive, fuel pump, steering gear – exploded with all fasteners, gaskets, and hardware called out. The subgroup index (page 17/1) groups these plates by system. The numerical index (page 19/1) lets you start from a part number and find which plate it lives on. That’s two paths to the same part: one from the system, one from the number. Both work if you know what you’re doing.

What Do the Miscellaneous Tables Cover?

Pages 1T through 5T are not spare parts plates; they’re reference tables for items that span multiple systems. Bearings (page 1T) gives you all the ball and roller bearings used in the tractor – dimensions and manufacturer codes. Electrical cables (page 3T) lists wire gauges and lengths for the harness. Terminals and boots (page 4T) and insulation tubes (page 5T) cover the connectors. If you’re rewiring a 300, you need these tables to source the correct crimp terminals. Aftermarket catalogs rarely reproduce this detail.

Modifications Tables: Factory Corrections You Can’t Ignore

Page 1M contains a table of modifications – engineering changes that happened during the 300’s production life. A part number superseded? A bolt pattern changed? It’s listed here. If you don’t cross-check the modification table against your tractor’s serial number, you might install a part that doesn’t clear the chassis. That kind of mistake costs a day of labor. The table is sparse but critical.

Why OEM Parts Catalogs Beat Aftermarket Copies

This is the original FIAT publication (Stampato n. 603.14.133). The part numbers in here are the ones Fiat assigned – not someone else’s renumbering. Aftermarket parts books often compress plates, omit the numerical index, or skip the modification table. You lose traceability. With this Fiatallis 300 Parts Catalog, you can hand a dealer a part number from page 19/1 and order it without debate. That’s the difference between a factory document and a cheap copy.

Frequently Asked Questions

Can I use this catalog for a Fiatallis 300B?

Only if the model list on orange paper (page 11) includes the 300B variant.

Are the part numbers in this catalog still valid for ordering today?

Some numbers have been superseded by later engineering changes, but the modification table (page 1M) lists the latest version. You’ll still get the correct Fiat part – just with an updated number. Always check the table before ordering.

Does the catalog include torque specs or maintenance procedures?

No. This is a parts catalog – it identifies parts and shows their locations. For torque values and service steps, you need the separate Fiat 300 service manual.

How do I read the exploded view plates?

Each plate has a reference number for every visible part. The part list above the plate gives the item number, part number, quantity, and description. The number next to the part on the plate is the item number, not the part number. This is a common mistake. Use the numerical index (page 19/1) to cross-reference part numbers directly if you’re unsure.

You’ve seen what an aftermarket parts list looks like – blurry images, missing pages, wrong numbers. This Fiatallis 300 Parts Catalog is the real factory document, 320 pages, with every plate and table intact. Access the Factory Manual and start ordering parts the way a pro would.
