Application & Compatibility
Source application path clues for buyer verification. These are source category/application paths, not confirmed fitment claims:
- CUMMINS > PERKINS > PERKINS 1103A 75HP
This turbine housing is listed for reference application on Perkins 1103A 75HP engines, with category clues also pointing to Cummins industrial applications. Because no OEM reference numbers are provided in the source data, treat the Perkins 1103A 75HP listing as a verification clue rather than a confirmed fitment. Buyers should cross-check part number 728643-0003 against their specific engine code and existing turbocharger configuration. Confirm that the square exhaust flange orientation and mounting details align with your unit before ordering. For applications where the housing is associated with Cummins engines, verify the specific engine model and production year to ensure the correct GT2049S variant is selected.
Technical Notes
The GT2049S turbocharger model is a fixed-geometry unit, meaning it does not utilize variable turbine geometry or adjustable vanes. This housing is a cast metal component designed to direct exhaust gases to the turbine wheel. Visible features include a square exhaust flange with four bolt holes and a volute-shaped body. Buyers should verify the specific material grade and mounting orientation against their existing unit, as these details are not confirmed in the source data. Confirm the housing matches the GT2049S configuration before installation to ensure proper alignment with the compressor side and engine block.
