Product FAQ

Casting numbers are physical identifiers on the turbo core, while OE reference numbers like 182647, 184180, and 311457 are catalog reference numbers. Buyers should match both to ensure the correct 311446 core is selected for their DT414 or DT436 engine.

Send casting numbers when the OEM references 182647, 184180, or 311457 do not fully match your application. This helps technical support confirm if the 311446 core is the correct replacement for your specific International or Case IH engine.

VIN confirmation helps verify the specific engine variant (e.g., DT414 vs. DT466) and production year. This ensures the 311446 core is the correct fitment for your vehicle before placing a B2B order.
