Technical Notes
The 4LE302 turbocharger is a fixed-geometry unit designed for heavy-duty diesel applications. This compressor housing is a standalone component, meaning it does not include the turbine housing, CHRA, or actuator. Before installation, verify that the mating surfaces are clean and free of debris. Ensure the compressor wheel is not damaged and spins freely without contacting the housing walls. Check the inlet and outlet ports for cracks or corrosion. Confirm that the OEM reference numbers 315775 and 4N3755 match your specific engine configuration. If the turbine side is also compromised, a complete turbocharger replacement may be more cost-effective than a component repair. Always verify the part number 156442 against your service manual before ordering.
