Cummins V-555, VT-555 Parts Catalog

If you are working on a Cummins V-555 or VT-555 and need replacement parts, the last thing you want is a wrong part number causing downtime. This Parts Catalog runs 46 pages of factory-sourced part numbers, exploded views, and ordering procedures. No reprint, no aftermarket guesswork – just the same documentation the Cummins dealers use.

Pay attention to the parts ordering instructions on page 3. The manual tells you to write your order clearly, list the correct part number, and always specify the engine model and serial number. Ignore that advice and you will get the wrong valve or gasket set. I have seen it happen too often.

You will find the exact part number for the camshaft and cover (section 6), crankshaft (section 3), cylinder block (section 1), and cylinder head (section 10). The electrical equipment section (section 37) covers alternator, starting motor, and related wiring. Every diagram is keyed to genuine Cummins part numbers.

Do not trust aftermarket parts catalogs that copy numbers from a PDF they found online. This is the original factory document. The V-555 and VT-555 engines are used in automotive, construction, and industrial applications, so the same catalog fits all those variants.

Camshaft and Cover – Section 6

The camshaft section lists the camshaft itself, bushings, cover, and all retaining hardware. If you are replacing a camshaft, you need the part numbers for the bushings (section 6 lists them separately). Do not reuse old bushings with a new cam – that will wipe out your oil pressure. The diagram shows the correct orientation of the cover gasket. Order the right gasket set from section 38 (Gasket sets).

Crankshaft, Main Bearings, and Vibration Damper – Section 3

Crankshaft part numbers are in section 3, along with main bearing shells and the vibration damper. Overhauling the bottom end? Get the main bearing shells from the same section. The vibration damper is a critical safety item – never reuse a damaged damper. The catalog lists the correct part number for the damper and the bolts. Torque specs for the damper are not in this catalog (that’s in the service manual), but the part numbers are correct.

Cylinder Block and Cylinder Head – Sections 1 and 10

The cylinder block section (1 page) gives the block part number and the cylinder liner part number. Section 10 covers the cylinder head, cylinder head cover, and associated valves. If you need a replacement head, use the part number from this catalog. The cylinder kit (section 4) includes pistons, rings, and liners as a set – often cheaper than buying individually. Check the piston ring part numbers against the ring groove specs; the catalog lists both standard and oversize rings.

Electrical Equipment – Section 37

Alternator, starting motor, fuel tubing, and the entire electrical harness are covered in section 37. If your VT-555 cranks slow, do not start swapping batteries until you verify the starting motor part number. The catalog shows the correct starter for your engine series. The same applies to the alternator – get the right model for your application. I have seen aftermarket catalogs list the wrong alternator bracket. This factory document will not do that.

Why a Factory Parts Catalog Beats Aftermarket Reprints

Aftermarket parts catalogs often omit the ordering instructions and the note that part numbers in parentheses are for identification only – not for ordering. This OEM catalog includes those warnings. It also lists the exact page numbers for each component group. The table of contents shows 46 pages of content, from air compressor to water pump. You can trust the part numbers because they come from Cummins, not a third-party copy machine. For more on diesel engine fundamentals, see this Wikipedia article on diesel engines. Also check the this Wikipedia article on diesel engines for background on the technology behind these engines.

Frequently Asked Questions

Is this just a parts list or does it include repair procedures?

This is a parts catalog. It lists part numbers and diagrams, not step-by-step repair instructions.

Can I use this catalog for a V-555 engine in a marine application?

The catalog explicitly says it covers automotive, construction, and industrial applications. Marine use may require different components such as corrosion-resistant alternators or different gasket materials. You should verify with your Cummins dealer whether the V-555 marine variant uses the same part numbers. The catalog does not list marine-specific options. That said, the base engine block, crankshaft, and many internal parts are often identical, but the auxiliary components (like the water pump or heat exchanger) will differ. Do not assume – compare your serial number.

How do I find the correct part number for the water pump?

Look in section 18 (Water pump, pulley, kit). The diagram shows the water pump assembly with individual parts listed. Cross-reference your engine serial number to ensure you get the correct pulley and mounting bracket. The part number for the complete pump is in bold.

Are the diagrams accurate for the VT-555 turbocharger?

Yes. Sections 29 and 30 cover turbocharger connections and the turbocharger itself. The diagrams are factory-accurate.

If you need to order parts for a Cummins V-555 or VT-555, stop relying on worn-out dealer photocopies or sketchy online lists. Access the Factory Manual from AutoRepairManuals and get the OEM part numbers you can trust.
