Fiat Powertrain Technologies F4HE9684P 2009 Parts Catalog

Working on a F4HE9684P and need to order parts? You want the exact OEM number, not a cross-reference that might be wrong. This 57-page Fiat Powertrain Technologies F4HE9684P 2009 Parts Catalog gives you the factory exploded views and part numbers. No reprints, no guesswork. Every bolt, gasket, and seal listed the way the engineers intended.

Page 1 alone shows the complete engine assembly (part 504146245), the overhaul gasket kit (8099009), and the valves grind set (8099010). If you are doing a full rebuild, you need those numbers to order from a dealer. The catalog is copyrighted 2002-2009 by FPT — it is the real thing.

Crankcase Assembly and Bolt Torque Specs (Page 2)

Page 2 breaks down the crankcase area: part 2830076 is the crankcase assembly itself. You get 14 hexagon bolts M12x120 mm (4891353), 6 screw connectors M8x1.25 (4894218), and 12 tappets (4899803). Also listed: oil nozzle assembly 504054307. The diagram shows exactly where each fastener goes. Handy when you are reassembling and need to confirm bolt length — six M12x120 bolts for the crankcase, not something you want to mix up.

If you are the type who torques every fastener, the catalog won’t give torque values (that’s in the service manual), but it gives you the exact bolt part numbers so you can order the right replacements. No guessing whether a M10x25 is the same as an M10x30 — the catalog shows which goes where.

Oil Sump and Suction Strainer – Component Breakdown

Page 4 covers the oil sump area. Oil sump assembly part 500388254, suction strainer 500388257, and the sump gasket 4897861. The flat engine gasket (4898301) and spacers are listed. Eighteen hexagon bolts hold the sump on (4899091). If you are chasing an oil leak, you want the correct gasket and bolt kit. This page also shows the threaded plug M22x1.5 (4894139) and an O-ring 2.62×23.47 mm (17282280).

The strainer pickup orientation is clear from the drawing. You can verify you have the right suction tube before dropping the pan.

Front Crankcase Cover: Seals and Bolt Upgrades

Page 5 gives the front cover details. The cover itself is part 4897027. Bolts: M8x30 up to engine serial #22680 (4899063), and from #22681 use a different mix. The catalog lists seven M8x30 and one M8x35 (4899019). Also includes a shaft seal (4890832) and two dowel pins (4891209). Overlook the seal update and you get an oil leak. The note at bottom calls out Loctite adhesive (2992504) — that is factory spec, not an aftermarket suggestion.

Worth noting: the front cover section cross-references to crankcase (0401) and other assemblies. If you need a specific bolt for the cover, the part number is right there.

Why OEM Part Numbers Matter for the F4HE9684P

Aftermarket suppliers often substitute parts that look close but are not the same. The F4HE9684P is a complete engine used in industrial and agricultural equipment — tolerances matter. Using a generic plug instead of the factory threaded plug M18x1.5 (4895392) can cause oil pressure loss. This catalog gives you the Fiat Powertrain Technologies part numbers so you source the exact piece. No adapter rings, no shimming. You get the right O-ring (4899072) and dowel pin (4899026). That saves you a second teardown.

Valves Grind Set and Overhaul Gasket Kit (Page 1)

Back to page 1: the valves grind set (8099010) is included in the catalog. If you are doing a valve job, you need the correct set of valve grinding compound and perhaps new valves. The kit number is listed. Same with the overhaul gasket set (8099009). These are Fiat Powertrain Technologies originals, not aftermarket copies. The complete engine assembly part (504146245) lets you order a whole long block if needed.

That is the beauty of a factory parts catalog — you can order individual components or the whole assembly, and you know they fit.

FAQ

Does this catalog include torque specifications?

No. This is a parts catalog, not a service manual.

Can I use this to order parts from a dealer?

Yes, because it contains OEM part numbers from Fiat Powertrain Technologies. The catalog lists every component from the crankcase to the oil sump, with official part numbers like 504146245 for the complete engine. You can give those to any Fiat dealer and get the exact factory part. The 57 pages cover the entire F4HE9684P engine, so you won’t be guessing which oil sump gasket fits. Just match the part number to the exploded view.

Access the Factory Manual and keep it on your bench. Having the correct part numbers prevents ordering the wrong bolt or gasket. Get the catalog, pull the part number, and move on to the next job.
