Description
What does an oil pump overflow valve do?
The oil pump overflow valve is a critical safety component within the lubrication circuit of heavy commercial vehicle engines. It functions by regulating the pressure generated by the oil pump, ensuring that levels remain within safe operating limits to protect the oil filter, seals, and gaskets from excessive force.Compatibility and technical specifications
This specific component is designed for compatibility with MAN engines. It features an M14x1.50 thread size, which is essential for precise fitment during engine maintenance or overhaul procedures. Using high-strength components ensures the valve can withstand the high-pressure environments found in heavy-duty engine cycles.Maintenance and installation guidance
For proper maintenance, technicians should perform a visual check of the valve seat and spring during routine oil changes to prevent contamination or scoring. Ensuring that sealing surfaces remain clean of carbon buildup is vital for preventing persistent leaks and maintaining correct pressure regulation.Troubleshooting and testing
When replacing this component, always verify that the spring orientation is correct to prevent disabling the pressure control mechanism. Check the oil pressure with a gauge at both idle and high engine speed to confirm the system is functioning correctly after installation.OE cross-reference
0102 083 (Oil Pump Overflow Valve Oil Pumps) is the equivalent of the MAN OE number. This part directly replaces MAN OE number 51054057017.Technical Specifications

FAQ
What is the function of this oil pump overflow valve?
It acts as a pressure regulator in the lubrication circuit, redirecting excess oil back to the sump when system pressure exceeds safe limits to protect engine seals and filters.
Which engines is this part compatible with?
This component is designed specifically for compatibility with MAN engines, featuring an M14x1.50 thread specification for precise installation.
How can I tell if the valve is failing?
Symptoms of failure include persistent oil leaks or fluctuations in engine oil pressure during testing at idle or high speeds.
What should I check during installation?
Ensure the spring orientation is correct and that all sealing surfaces are completely clean to prevent carbon buildup from hindering the valve's movement.
What are the OE reference numbers of this part?
0102 083 directly replaces MAN OE number 51054057017.
