Similarly, the Turbo Oil Supply Tube is compatible with the X11 CM2670 X126B, X12 CM2670 X121B, and X13 CM2670 X122B engines. These engines belong to the Cummins X series, which is widely used in marine and industrial applications. The part number 3692479 is engineered to fit these engines, ensuring that the turbocharger receives the required oil flow. This compatibility is crucial for maintaining the engine’s efficiency and preventing potential damage due to inadequate lubrication.

Role of Part 3692479 Turbo Oil Supply Tube in Engine Systems

The Turbo Oil Supply Tube (part 3692479) is an essential component in the lubrication system of turbocharged engines. Its primary function is to deliver pressurized oil from the engine’s lubrication system to the turbocharger. This ensures that the turbocharger’s bearings and other moving parts receive adequate lubrication, which is vital for their operation and longevity.

Integration with Turbocharger

When integrated with the turbocharger, the Turbo Oil Supply Tube connects to the oil inlet port of the turbocharger. This connection allows oil to flow into the turbocharger housing, where it lubricates the turbine and compressor bearings. Proper lubrication reduces friction and wear, enabling the turbocharger to operate efficiently and reliably under high-stress conditions.

Interaction with Plumbing

The Turbo Oil Supply Tube is part of the engine’s oil plumbing system. It is typically connected to the oil supply line, which branches off from the main oil gallery. This setup ensures a consistent flow of oil to the turbocharger, even under varying engine loads and RPMs. The tube may also incorporate features such as filters or restrictors to regulate oil flow and pressure, maintaining optimal lubrication conditions.

Lubrication System Dynamics

In a well-designed lubrication system, the Turbo Oil Supply Tube works in conjunction with other components such as the oil pump, oil filter, and relief valve. The oil pump generates the necessary pressure to push oil through the supply tube, while the oil filter ensures that contaminants are removed from the oil before it reaches the turbocharger. The relief valve helps maintain consistent pressure within the system, preventing over-pressurization that could damage components.

Maintenance and Monitoring

Regular maintenance of the Turbo Oil Supply Tube is essential to ensure the turbocharger and engine operate efficiently. Inspections should check for signs of wear, leaks, or blockages in the tube, as these issues can lead to inadequate lubrication and potential turbocharger failure. Monitoring oil pressure and temperature can also provide insights into the health of the lubrication system and the effectiveness of the Turbo Oil Supply Tube.
