Description
What does an oil pump overflow valve do?
The oil pump overflow valve serves as a critical safety component within the engine lubrication circuit. By regulating the pressure generated by the oil pump, this component prevents excessive buildup that could otherwise damage seals, gaskets, or the oil cooler. It operates by redirecting excess oil back to the sump once a specific pressure threshold is reached, ensuring stable lubrication for all engine components.Compatibility and technical specifications
This specific part is designed for compatibility with MAN engines. It features an M13x1.75 thread size to ensure a precise fit during installation. Maintaining the correct thread and seating is vital for preventing pressure drops or leaks within the lubrication system.Installation and maintenance guidance
For optimal performance, technicians should inspect the valve seat and spring during routine oil changes to check for contamination or scoring. Ensuring that the spring is correctly oriented during installation is essential to prevent failures in pressure control. Always verify that the oil viscosity matches manufacturer requirements to maintain correct valve behavior.Troubleshooting and inspection

FAQ
What is the function of an oil pump overflow valve?
It acts as a pressure regulator in the lubrication circuit, opening to redirect excess oil back to the sump when system pressure exceeds safe limits.
What thread size does this component use?
This specific overflow valve is designed with an M13x1.75 thread specification for precise installation.
How can I know if the valve needs replacement?
Technicians should look for signs of contamination, scoring on the seating surfaces, or persistent oil pressure irregularities during engine testing.
What should be checked during installation?
It is crucial to verify spring orientation and ensure all sealing surfaces are clean to prevent improper seating and pressure loss.
What are the OE reference numbers of this part?
0102 085 directly replaces MAN OE number 51054055019.
