Technical Notes
The HX40W turbocharger is a fixed-geometry unit, meaning it does not use variable turbine geometry (VNT) vanes. During installation, verify that the compressor and turbine shafts rotate freely without binding. Confirm that the compressor wheel inducer and exducer dimensions match the OEM reference numbers 4039744 and 4039745 to ensure correct airflow characteristics. If an electronic actuator is present on your specific application, follow the vehicle manufacturer’s setup details procedure after installation to initialize boost control.
