Technical Notes

The HX55WM turbocharger is a fixed-geometry unit, so this turbine housing does not include variable-geometry vanes or an actuator. Verify the housing material and casting details against your existing unit to ensure thermal and structural suitability for Scania DLC6 applications. Confirm that the turbine inlet flange matches the exhaust manifold geometry and that the V-band clamp profile aligns with the compressor side. Check the oil and water connection ports for correct thread sizes and O-ring material compatibility. Use the eight associated OEM reference numbers, such as FOR 1939499 TH and FOR 3779274 TH, to cross-check part identity before installation. Technical fitment support is available to assist with these verification steps.
