Role of Part 5267704 Turbo Oil Supply Tube in Turbocharger Plumbing

The Turbo Oil Supply Tube, identified by part number 5267704, is an essential component in the turbocharger plumbing system. This tube facilitates the delivery of pressurized oil from the engine’s lubrication system to the turbocharger ³.

In the turbocharger plumbing, the Turbo Oil Supply Tube connects to the oil feed line, which originates from the engine’s oil pump. The oil pump draws oil from the sump and pressurizes it before sending it through the oil feed line. The Turbo Oil Supply Tube then directs this pressurized oil to the turbocharger’s bearing and turbine housing ³.

Once the oil has lubricated the turbocharger’s components, it returns to the engine’s sump through the oil return line. This return path ensures that the oil is recirculated and can be re-pressurized by the oil pump, maintaining a continuous lubrication cycle ³.

The Turbo Oil Supply Tube also interfaces with the oil filter, which is part of the oil feed line. The oil filter removes contaminants from the oil before it reaches the turbocharger, ensuring that only clean oil is supplied to the turbocharger’s sensitive components ³.

Additionally, the Turbo Oil Supply Tube may connect to an oil cooler, which helps to regulate the temperature of the oil before it reaches the turbocharger. This temperature regulation is vital for maintaining the viscosity of the oil, which in turn ensures effective lubrication and cooling of the turbocharger’s components ³.

Conclusion

The Turbo Oil Supply Tube, part number 5267704, is a critical component in the Cummins QSB6.7 CM2250 engine, contributing to the engine’s durability and performance. Its design and functionality are tailored to meet the specific needs of this engine series, ensuring optimal operation and longevity ³.
