This 7N7251 T1227 core is listed for CAT D342 and CAT 583H applications, with reference clues extending to CAT D8K earth-moving equipment. The supplied OEM reference numbers, including 0R5915 and 407505-0016, serve as verification aids rather than confirmed fitment confirms. Buyers should cross-check the part number, engine code, and specific turbo configuration against their unit before ordering. This aftermarket replacement application is intended for repair shops and fleet maintenance teams who require a rebuild core for T1227 series turbochargers. Verify all application details to ensure the core matches your specific repair requirement.

Technical Notes

The T1227 core assembly features a central cast housing with a visible mounting flange and two threaded mounting holes. The turbine wheel is positioned at the top with curved blades, while the compressor wheel is located at the bottom. A shaft nut is visible at the top of the assembly, and machined metallic surfaces are evident on both housings. The symmetrical arrangement of the wheels supports standard rebuild procedures. Buyers should verify the physical configuration against their specific unit to ensure the mounting flange and wheel dimensions align with their repair requirements.
