The HX40W is a fixed-geometry turbocharger commonly used in medium-duty diesel applications. Buyers should inspect the existing unit's nameplate to confirm the model designation matches HX40W. Verify the compressor and turbine housing configurations against your current setup. Note that gross weight is 16 kg and packing dimensions are 26x30x33 cm, which aids in logistics planning. If your existing turbo has a different model number or housing style, do not assume interchangeability. Contact technical support with your engine serial number for precise identification.
