FAQ

Q: How do I confirm that this C5662123 block fits my Cummins 6L engine?
A: While this block is designed for the Cummins 6L series, we recommend checking your engine serial number and the casting numbers on your existing block. If your current block has the C5662123 casting number, this is a direct fit. For custom rebuilds, verify the main bearing journal size and bore diameter match your specifications.

Q: What is the standard bore size for this cylinder block?
A: This block is supplied at the standard OEM size. If you are rebuilding an engine, you will need to measure your pistons. Typically, standard blocks are honed to a specific tolerance. If your pistons are oversized (e.g., 0.50mm or 1.00mm over), this standard block may require machining or you may need an oversized block. Please consult your engine manual for the exact specifications.

Q: Does the block come with freeze plugs or main bearing caps installed?
A: The cylinder block is typically supplied as a bare casting. It includes the main bearing caps but may not include freeze plugs, dowel pins, or other ancillary hardware unless specified. Please check the product listing or contact our sales team to confirm what is included in the specific shipment. We recommend ordering necessary gaskets and seals separately for a complete rebuild.
