Cummins V-504 Parts Catalog – 44-Page Factory Parts Breakdown

If you’ve ever ordered a part for a Cummins V-504 and ended up holding the wrong piece because the aftermarket catalog showed a fuzzy drawing, you know the waste of time I’m talking about. That stops here. This is the factory Cummins V-504 Parts Catalog – 44 pages of nothing but genuine part numbers, exploded views, and the exact ordering info Cummins intended. No reprints, no third-party guessing.

I’ve seen guys tear half an engine down only to realize the replacement piston ring set had the wrong tang location. That’s a parts catalog fail, not a mechanic fail. This manual fixes that. It covers the V-504 in automotive, construction, and industrial applications – V8-210, V-504-C210, V-504-P210. You get the factory drawings for every system: cylinder block, cylinder head, crankshaft, camshaft, valve train, fuel system, electrical mounting, water pump, oil pump, and more. Each section has a clear parts list with numbers you can hand straight to your dealer.

Which Engine Applications Does This Catalog Cover?

The foreword calls out three distinct application codes: A for automotive, B for off-highway less air compressor, C for construction/mining mobile equipment, P for industrial radiator-cooled stationary. These are not the same engines – different mounts, different accessories. The catalog uses an “X” in the application box on each page to tell you which parts go where. If you’re running a V-504 in a grader, you need the C-series parts callout. This manual has it.

Use the Correct Part Numbering System

Cummins wants your order typed, part numbers in numerical sequence, and engine serial number included if you’re unsure. That’s on page 4 of this catalog. I’ve had parts jockeys throw their hands up when I gave them an aftermarket reference number. With this factory catalog, you have the actual Cummins part numbers – cast into the parts themselves. Cross-check the number in the book with the number on the part before you install it. Saves you one trip back to the counter.

Crankshaft, Camshaft, and Cylinder Head: Critical Components

Three sections I always turn to first: Crankshaft (section 03), Camshaft (section 06), and Cylinder head (section 09). These are the high-failure, high-cost parts on any diesel. The exploded view in this catalog shows every bushing, bolt, and seal. If you’re rebuilding a V-504 bottom end, you need the factory part numbers for main bearings, thrust washers, and the crankshaft gear. Don’t mix up the camshaft between automotive and industrial – the drive gear can differ. This catalog gives you the visual reference to confirm what your engine actually has installed. Check the serial number on the data plate against the application table on page 5.

7 Systems Covered at a Glance

The table of contents lists 36 numbered sections, but seven major system groups stand out for field service: Air cleaner (25), Fuel system (30), Electrical mounting (35), Oil pump/pan/filter (12-15), Water pump/head cover (17, 02), Valve cover and rocker levers (10, 08), and the full Cooling bundle including radiator/fan (20), fan high mount (22), and water crossover (19). Each section is a two-page spread max – part number, description, quantity. No fluff, no filler. You can find the fuel pump drive components in section 28, the injector and shutdown valve in section 31. Everything is indexed to page numbers at the bottom.

Does This Catalog Include Fuel and Electrical System Parts?

Fuel system is section 30, and it covers the full injection line – fuel tubing (34), fuel pump drive (28), injectors, shutdown valve (31). The Electrical mounting section (35) includes brackets, harness clips, and mounting hardware for alternators and starters. It’s not a wiring schematic – this is a parts catalog. You get the correct bracket and pulley part numbers so you don’t end up with a belt that’s half an inch too long. For the valve train, sections 07 (push rods and tappets), 08 (rocker levers), and 10 (valve cover) give you every snap ring and retainer. If you need a valve stem seal, you need the head section (09) for that.

I’ve used factory parts catalogs for years. Aftermarket compilations always miss one bearing shell or use a generic image that doesn’t match. This manual is an original Cummins print. The ordering instructions on page 2 tell you to check the model and serial number – that’s the right approach. For more background on diesel engine fundamentals, read this Wikipedia article on diesel engines. You can also cross-reference this catalog with other Cummins powerplants like the Cummins VME W380 Parts Catalog | 626-Page Factory Manual or the Cummins QSX15-G8 2011 Parts Catalog – OEM Factory Manual. For a smaller V-engine variant, check the Cummins V-378 Parts Catalog – OEM Factory 37-Page Manual.

Do I need to know my engine serial number to use this catalog?

Yes. The catalog cross-references part numbers by application code (A, B, C, P) and serial number. Without the serial number, you risk ordering a camshaft for a different application. The manual tells you to list the serial number if the part number is uncertain – that’s straight from the factory.

Can I use this catalog to order parts from any Cummins dealer?

Yes. These are the official Cummins part numbers used at every Cummins distributor and dealer worldwide. The catalog includes a statement that there are over 2400 sales and service locations in the US and Canada. Present this page with the correct part number and the dealer will process your order without confusion.

This catalog belongs on your bench next to the torque wrench. You stop guessing part numbers, you stop reordering because the aftermarket diagram was wrong. Access the Factory Manual now and keep your Cummins V-504 running with parts that actually fit.
