Application & Compatibility
Source application path clues for buyer verification. These are source category/application paths, not confirmed fitment claims:
- Orion Bus > Orion V > Orion V Transit Bus > CUMMINS ISM
This core is listed for CUMMINS ISM engines, with a reference application for Orion V transit buses. The application path is Orion Bus > Orion V > Orion V Transit Bus > CUMMINS ISM. Use this path as a verification clue, not a confirmed fitment. Before ordering, verify the part number 4027728, the specific ISM engine code, and the turbo configuration on your existing unit. Confirm that the HX50 core matches your turbine and compressor housing orientation. If the application is non-standard, send a dimensional photo of the existing core to technical support for fitment confirmation.
Technical Notes
The HX50 core assembly is designed for heavy-duty CUMMINS ISM applications. No VNT, variable-geometry, or specific cooling system details are provided in the source data; therefore, do not assume these features are present. Verify the physical configuration of your existing unit against the new core. Confirm the turbine and compressor housing orientation, shaft alignment, and mounting details before installation. If the application is non-standard, provide a dimensional photo to technical support for fitment confirmation. This ensures the selected 4027728 core matches your specific engine bay layout and turbo configuration.
