Fiat Powertrain Technologies 850, 850 Germania Parts Catalog

If you work on Fiat tractors — and I mean the old iron, not the modern computer-on-wheels — you already know the pain of ordering a part that looks right but isn’t. A bolt with the wrong pitch, a gasket that’s a millimeter off, a bearing that doesn’t fit the housing. That’s time and money down the drain. This Fiat Powertrain Technologies 850, 850 Germania Parts Catalog stops that. It’s the real factory print, not some aftermarket re-scan with washed-out drawings. 463 pages, Italian, French, English, German — my shop uses the English section, but the diagrams speak universal.

I’ve torqued more head bolts than most techs have had hot meals, and I know that pulling the wrong part number leads to a comeback. This catalog gives you the exact OEM part numbers for both the standard 850 and the 850 Germania variant. You’ll find exploded views of every subassembly — from the main engine block to the front axle and steering. No fluff, no generic drawings. Just the factory’s own illustrations with callouts that match the part numbers you order.

Engine Assembly Breakdown – A0 through A108

The catalog starts with the complete engine assembly (A0) and works down through every subsection. A101 covers the main bearing and cylinder head area. A102 is the cylinder block and head itself. A103 is the oil pan and covers. A104: crankshaft and flywheel. A105: the vibration damper mass. A106: rods and pistons. A107 and A108 handle the timing drive and valve train. If you’re rebuilding a 850 or 850 Germania motor, you need these 463 pages to cross the parts off against your teardown. The subgroup index is on page 17/1 — start there, find your model code (01 for 850, 02 for 850 Germania), and then look up the plate number.

850 vs 850 Germania: Know Your Model Code

You’d be surprised how many guys order parts for a standard 850 and slap them on a Germania. Some stuff swaps, but the intake manifold gasket and the injection pump brackets are different. The catalog lists each model separately with its own code. Flip to the orange paper — page 11. The 850 is code 01, the 850 Germania is code 02. Use the wrong code and you’ll get the wrong plate. I’ve seen a shop order a cylinder head gasket for the standard 850 and then wonder why the coolant ports didn’t line up. Don’t be that guy.

What’s Inside the Subgroup Index?

Beyond the engine, the catalog covers the complete tractor: front axle, transmission, pto, hydraulics, steering, brakes, electrical. Each subgroup has its own index and plates. The subgroups are numbered — for example, MOTORE E SUPPORTI (A1) includes the engine mounts and the power plant assembly. The catalog uses exploded isometric drawings with part numbers directly on the image. No separate legend to flip back and forth. You look at the drawing, you see the number, you order that number. It’s clean. The only catch: the text for notes is in four languages, so English warnings are on page 9. Read them before you start pulling parts.

3 Reasons to Choose the Factory Catalog Over Aftermarket

First, aftermarket parts catalogs often compress multiple model years into one page and miss the subtle differences. This is the official Fiat Powertrain Technologies document. Second, the drawings here are original lithographs, not re-scanned low-res jpegs. You can read the part numbers on a 10-point bolt without guessing. Third, you get the actual model cross-reference — the 850 Germania has unique parts that aftermarket catalogs ignore. If you’re restoring a Germania and you want the correct tie-rod end, this catalog is your only shot.

Using the Manual on the Bench

Print out the plate for the section you’re working on. Tape it to your tool box. Then go through your disassembled parts, compare the drawing, and write the part number on a bag. That’s how my guys do it. Also check the Fiat & Abarth Tricks Technical Manual if you need special rebuild tips. For other Fiat tractor parts, see the FIAT Serie 415 Parts Catalog (Ricambi) or the FIAT Trattori Serie 555 Spare Parts Catalogue 2ª Edizione. They’re laid out the same way. And if you want the bigger picture on how these engines fit into the history of tractor design, read the Automotive Industry Overview or brush up on the Internal Combustion Engine basics.

This catalog is 463 pages of pure factory spec. No third-party reprints, no faded copies. You get the exact same document that Fiat sent to dealers in 1971. Access the Factory Manual and stop guessing which part fits.

Does this catalog include torque specs and repair procedures?

No. This is a parts catalog, not a service manual. You get exploded diagrams and part numbers only. For torque values and overhaul steps, you need the separate workshop manual.

How do I find the correct part for my 850 Germania?

Look at page 11 (orange paper) to identify your model code. The 850 Germania is code 02. Then go to the subgroup index starting at page 17/1. Each subgroup covers a section of the tractor. Find the plate number that matches your area (e.g., A106 for connecting rods and pistons). The drawing will show all parts with callout numbers. Cross-reference those numbers to the part list on the adjacent page. Order using the Fiat part number shown. If the part number is superseded, you’ll find the update in the catalog’s revision notes. Always verify your model code first — the standard 850 and 850 Germania share many parts but not all. I’ve seen the wrong water pump installed because a guy didn’t check the code. Don’t waste time.
