Technical Notes
The HX40W turbocharger is a fixed-geometry unit. Technical verification focuses on confirming the turbine and compressor housing dimensions, shaft alignment, and bearing assembly integrity. Buyers should inspect the turbine end for piston ring seal size and condition, as well as the compressor wheel for surface damage. Verify the journal bearing material and design against your rebuild specifications. For the 4036378 application, cross-check the thrust bearing type and load capacity to ensure it matches the CUMMINS ISC engine requirements. Our technical support team can assist with these fitment checks.
