Product FAQ

This turbocharger is associated with OEM reference numbers 3799121, 3799122, and 5327313. Use these numbers to help confirm fitment for your Cummins QSK50 application.

Buyers should measure the inducer and exducer diameters of the original unit or consult the technical datasheet. Matching these dimensions ensures proper airflow and pressure ratios for the QSK50 engine.

Inspect the shaft diameter and material composition against the supplied reference details. Ensuring the shaft matches the original tolerances helps maintain bearing alignment and operational stability.

Check that the oil feed and return port sizes and positions match the engine's lubrication system. Incorrect port alignment can lead to oil starvation or leakage, so verify these details before installation.
