Fiat Powertrain Technologies 8361 Parts Catalog – Factory Specs for Diesel Engine Rebuilds

If you have ever tried to order a piston ring for a Fiat 8361 diesel engine using an aftermarket parts list, you know the drill. The part number is wrong. The diagram shows a different cylinder head. You waste an hour on the phone. This Parts Catalog was printed by Sperry+New Holland for the Fiat Powertrain Technologies 8361 engine, and it fixes that. 71 pages of factory-original part numbers, grouped by engine system. No third-party guessing. For a solid primer on diesel fundamentals, see this Wikipedia article on diesel engines.

40 Groups of Exploded-View Diagrams

Every group in the 71 pages follows a logical order: oil sump, covers, cylinder head, cylinder, crankshaft, connecting rods, piston, flywheel, damper, gears and shafts, drive gears, rocker arms, valves, injection pump, advance variator, nozzles, injection lines, speed regulator, nozzle holder, governor weights, lines, fuel filter, fuel pump, delivery pump and drive, lines and injectors, pressure regulating valve, heat exchanger, oil filter, water pump, lines, heat and pressure regulator, fan drive, starter motor. That is 40 groups total. Each group has its own figure with FIAT and Sperry New Holland part numbers listed side by side. Quantities and descriptions included.

That is the point. You get one PDF with every component broken out. The alternator mount on page 2 shows part numbers 4953100 and 13556921 with washer and nut specs. Cross-reference any part without calling a dealer.

Crankshaft and Cylinder: What the Catalog Tells You

Group 9 is the crankshaft. Group 5 is the cylinder. If you are rebuilding the bottom end, you need the correct bearing shells, thrust washers, and seals. The catalog gives you the exact part numbers for each variant. Do not rely on generic bearing catalogs for an 8361. The cylinder block itself is shown in Group 5 with all associated components. You also get the flywheel (Group 12) and damper (Group 13) numbers. Without this, you risk ordering a six-bolt flywheel for a four-bolt crank.

Why a Parts Catalog Matters More Than a Service Manual

A service manual tells you how to torque a head bolt. A parts catalog tells you which head bolt to buy. Without the right part, your torque spec is useless. This catalog was issued by Sperry+New Holland, division of Sperry Rand Belgium, in 1978. It is OEM documentation, not a third-party reprint. If you also work on other Fiat industrial engines, check out the Fiat Powertrain Technologies 415 Parts Catalog – OEM Tractor Parts Manual for similar factory drawings. For the smaller agricultural models, Fiat 850 & 850 Germania Parts Catalog – OEM Factory Specs is another useful reference. And for the larger 555 engine, Fiat Powertrain Technologies 555 Parts Catalog – 287 Pages OEM covers more ground.

Order Parts by Group Number

Each group in the TOC has a corresponding figure number. Locate the assembly you need, read the parts list, and order directly. The catalog uses metric hardware throughout. No converting thread pitches from generic sources. For a deep dive into the injection system used in this engine, refer to this Wikipedia article on diesel engine.

71 Pages of Factory-Correct Data

The table of contents lists 40 groups, each with multiple figures. Page 1 shows the service parts catalogue title block confirming engine type 8361 I – 152 PK. Page 2 shows the alternator mount assembly with FIAT part numbers. The rest of the manual follows the same dense format. No generic diagrams. No aftermarket interpretation. You get the exact same document that dealer parts counters used in the 1970s.

Does this catalog cover the Fiat 8361 engine?

Yes. It covers the 8361 I model as shown on the title page.

Can I use this to rebuild the entire engine?

This is a parts catalog, not a service manual. It lists every part with exploded diagrams and part numbers. For a rebuild you need both a service manual for torque specs and clearances. But with this catalog you can identify every seal, bearing, and gasket by OEM number. If you are ordering parts for a full rebuild, you will reference groups 1 (oil sump) through 40 (starter motor). The cylinder head group (4) shows valve guides, seats, and springs. The injection pump group (19) shows components inside the pump. Without this catalog you risk ordering the wrong parts for the 8361.

Are the part numbers still valid?

Fiat Powertrain Technologies may have superseded some numbers. But the catalog gives you the original FIAT and Sperry New Holland part numbers. You can cross-reference with current dealer catalogs. Most internal engine parts for the 8361 are still available.

Is this a digital PDF or a printed manual?

Digital PDF.
