Cummins 5297674 Turbo Oil Supply Tube

The Cummins 5297674 turbo oil supply tube is a precision-formed rigid metal line designed to deliver pressurized engine oil to the turbocharger bearing cartridge. It is engineered for Tier 4 emissions-compliant 6.7 liter ISB and QSB engine platforms, specifically the QSB6.7 CM2350 B105 configuration. Constructed from high-temperature alloy steel with corrosion-resistant coating, the assembly includes pre-formed bends and flared fitting ends to ensure leak-free sealing at the engine block and turbocharger center housing connections. This component is critical for maintaining turbocharger rotor dynamics and preventing bearing starvation under high thermal loads. Direct OEM replacement for Cummins part number 5297674.
