Perkins RH38009 2004 Parts Catalog

If you’re wrenching on a Perkins RH38009 – specifically the 1104C-E44T – and you’re tired of guessing which piston ring goes where or what the factory part number is for that cylinder liner, this is the only document that matters. I’ve been in the trade 28 years and I’ve seen more engines rebuilt with aftermarket catalogs that had the wrong crankshaft bearing specs than I care to count. This 2004 Parts Catalog from Perkins Engineering is the real deal: 181 pages of OEM illustrations, part numbers, and assembly references. No guesswork, no third-party copy. Just the factory data.

Engine Breakdown: From Cylinder Block to Crankshaft

Open to page 5 and you’ll find the Engine Breakdown table. That’s your roadmap. It lists every major section – from the Short Engine (ACE40005) to the Flywheel & Starter Ring (DDHR0552). The section on Cylinder Block & Liners starts on page 15, right before the Crankshaft, Main & Big End Bearings section on page 17. If you need the part number for a piston ring set, page 19 covers Pistons & Rings. This isn’t a generic overview; it’s the exact exploded view used by factory assemblers in 2004. The Crankshaft assembly is drawn with matching bearing shell sizes – you won’t find that in an aftermarket PDF.

Does This Parts Catalog Replace the Service Manual?

No. This is a parts catalog, not a repair procedure book. You still need the Service Manual for torque sequences, clearances, and assembly steps. What this does give you is the correct OEM part number for every component on the Engine – including the Cylinder head assembly (page 25), rocker shaft (page 27), and timing gear (page 29). If you’re ordering parts, quote the build list from the front page. The catalog is useless if you don’t match that serial number. Check page 4 – the introduction tells you exactly how to use your build list.

3 Reasons to Stick with OEM Perkins Documentation

First, the illustrations are representational but the part numbers are the only ones that fit. Second, the Parts Index (page 174 to 181) lets you look up any description or number in seconds. Third, you avoid the headache of buying a part that looks right but has a different bore diameter or thread pitch. I’ve seen guys install the wrong connecting rod because an aftermarket catalog listed the same dimensions – it cost them a rebuild. This 2004 Parts Catalog eliminates that risk.

Symbol Descriptions: What Those Marks Mean

Page 9 lays out the symbols used throughout the Parts Lists & Illustrations. Some indicate parts that must be replaced as a set, others show items not sold individually. If you ignore those symbols, you’ll end up with a box of mismatched bolts. The manual calls out exactly which marks apply to each section – like the Flashfile Software entry on page 13. For the RH38009, you’ll see notes about mounting brackets and fuel injection pump parts (page 31). Always cross-check the symbol before you order.

How to Find Parts Using the Parts Index

The last eight pages of the book – starting page 174 – are a straight alphabetical and numerical index. Say you need the high-pressure fuel pipe: look up “Fuel Pipe, High Pressure” or search the part number AFHR4215. The index sends you to page 33, where the actual illustration shows each pipe’s routing. That’s faster than flipping through every engine breakdown section. Pair this catalog with the Service Manual, and you’ll have every factory spec you need.

Related manuals you should have in your library: Perkins Engine D3.152 Parts Catalog Diagrams, Perkins Engine 4.248 Parts Manual – Section: Cylinder Block, and Perkins 404C-22T 2006 Parts Catalog. Each one follows the same OEM layout – no reprints, no copy errors.

Does this catalog include torque specs?

No. This is a parts identification reference, not a service manual. Use it to order correct parts.

What if my engine serial number doesn’t match the build list on the front page?

Then this catalog may not match your engine exactly. Perkins built variations of the 1104C-E44T, and the parts book is specific to the RH38009 build list printed on page 1. Call your local Perkins dealer with your serial number to verify compatibility. If you’ve bought this catalog for a different engine code, you risk ordering parts that don’t fit. Always confirm the engine code – I’ve seen a misplaced decimal in a serial number cause a three-week delay. Check the symbol descriptions on page 9 first, then cross-reference the part number in the index. If you’re rebuilding a short engine (section ACE40005), you need the correct cylinder block liner size – that data is only valid for the original build.

Bottom line: if you need to identify parts for your Perkins RH38009, access the factory manual directly from AutoRepairManuals. Your rebuild will go faster, and you won’t waste money on the wrong crankshaft bearings.
