Fiat-allis 850 Super, 850 DT Super Parts Catalog – 596-Page OEM Factory Manual

You’re looking at a parts pile that doesn’t match the machine. Happens every time someone orders from a worn casting number or a third-party cross-reference. I’ve pulled wrenches long enough to know that one wrong part number can shut down a job for a day. The Fiat-allis 850 Super, 850 DT Super Parts Catalog is the factory document – 596 pages of what Fiat Trattori intended to be used. No translations from aftermarket sources. No guessed part numbers.

This catalog came out of Modena, Italy. Printed under copyright by FIAT. It covers the 850 Super and the 850 DT Super models. Everything from the engine to the final drive is listed with the exact OEM part numbers and exploded views. Page 11 gives the full model list – on orange paper so you can flip to it quick. Page 1T has bearing specifications for every rotating assembly. If you’re rebuilding a transmission or replacing a hydraulic seal, this is the reference you need on the bench.

Fiat-allis 850 Super and 850 DT Super Parts Catalog – What You Get

The binder is organized by subgroup index (starts on page 17/1). That’s the backbone. You look up your assembly – say the final drive – find the subgroup number, then flip to the corresponding spare parts plates and list. Each plate shows the exploded view with callouts. The list next to it gives the OEM part number, quantity, and description. No ambiguous “use with” notes that leave you guessing. Fiat’s engineers drew every bolt and seal.

Ordering Parts: Use the Correct Number

Page 5 spells out the ordering rules. You need to supply the model, serial number, and the part number from this catalog. If you call your dealer with a casting number from a worn housing, you’re rolling dice. This catalog gives you the reference to order exactly what Fiat put on the line. I’ve seen a guy order a seal kit based on a rusty ID tag – ended up with the wrong O-rings. This catalog fixes that.

Also in the front: the variations list on orange paper, page 13. That section catches machines that had mid-production changes. If your 850 DT Super has a different hydraulic pump mount, it’s noted there. Ignore that list and you might order a part that fits the early model but not yours.

3 Languages – Which One Do You Need?

The catalog is printed in Italian, French, English, German, and Spanish. The English section starts with “Contents” on page 9. The subgroup index and spare parts index are identical across languages – numbers and diagrams don’t change. But the instructions for use are in each language. If English is your shop language, page 9 walks you through how to read the catalog. No translation guesswork.

Miscellanea Tables: Bearings, Cables, Insulation Tubes

After the spare parts section, the catalog includes standard parts tables: bearings (page 1T), electrical cables (page 3T), terminals and boots (page 5T), and insulation tubes (page 7T). These are the generic parts that cross over to other Fiat machines. If you need a wire terminal for a harness repair, check page 5T for the OEM terminal part number. That’s faster than measuring and guessing a replacement.

The modifications section (page 1M) lists factory updates – part number supersessions and design changes. Always check this section before ordering. A part might have been phased out and replaced with a newer number. The catalog shows which old numbers are discontinued and what replaces them.

Why Factory Specs Beat Aftermarket Catalogs

Aftermarket parts catalogs often copy from earlier editions and miss revisions. They might omit the variations list or the modification tables. Or they reprint a 1970s version without updates. This catalog is a direct scan of the original Fiat Trattori publication. Every part number and diagram is as printed in Modena. You can trust that if it shows a 10mm bolt with a specific shoulder length, that’s what Fiat used. I’ve been burned by aftermarket catalogs that listed a part number that was superseded five years ago. This one won’t do that.

FAQ

Is this catalog in English?

Yes. Page 9 gives the English instructions. Plates use universal part numbers.

Can I use this to rebuild the engine?

This is a parts catalog, not a service manual. It lists every OEM part number for the engine (pistons, rings, bearings, gaskets) but does not include removal or torque procedures. For rebuild steps, you need the factory service manual. However, having the exact part numbers from this catalog eliminates the risk of ordering wrong components. I’ve seen many shade-tree rebuilds fail because a guy used a generic seal that didn’t match the groove profile. Use this catalog to get the genuine Fiat parts, then follow the service manual for assembly. The subgroup index on page 17/1 points you to the exact engine assembly group.

Stop ordering parts from memory or worn-out casting numbers. Get the factory reference that the dealership uses. Access the Factory Manual now and keep it in your shop tablet.
