Cummins 2830895 Turbocharger Oil Drain Connection

The Cummins 2830895 is a turbocharger oil drain connection designed for the 15-liter engine platform, specifically the QSX15 and ISX15 series. This component facilitates the return of lubricating oil from the turbocharger bearing housing back to the engine crankcase. It is engineered to withstand high thermal cycles and oil pressure pulses inherent in heavy-duty diesel applications. The connection features an OEM-specific flange profile and sealing surface to prevent oil leakage. It serves as a direct replacement for the factory-installed drain connection on compatible Cummins 15L engines. Verification via engine serial number (ESN) is required prior to installation to ensure correct configuration.
