Technical Notes

This core is a rotating assembly component for the Cummins N14 14.0L diesel engine. It is not a complete turbocharger; it does not include turbine or compressor housings. Buyers should verify that their existing turbocharger housings are undamaged before selecting this core-only replacement. Confirm the specific engine code and OEM reference numbers FOR 3523417 or FOR 3523418 against your vehicle records. If the housing is cracked or worn, a complete turbocharger assembly may be required instead of this core component.

Product FAQ

This core is associated with OEM reference numbers FOR 3523417 and FOR 3523418. Verify these references against your specific Cummins N14 engine configuration.

Symptoms include excessive smoke, loss of power, or oil consumption in Cummins N14 applications. Inspect the core for bearing wear or shaft play before replacement.

If the turbine or compressor housings are damaged, or if multiple components are worn, replacing the complete turbocharger may be more efficient than swapping only the core.

Choose this core if the housings are intact and only the internal rotating assembly is worn. This reduces cost and preserves existing housing condition.
