Oberdorfer 1838 Nut – OEM Pump Replacement Part
The Oberdorfer 1838 is a small hardware component. Parts like this hold the assembly together and set the position of components that would otherwise move, and they are the ones most often lost or damaged during a strip down.
Retaining and locating hardware sets endfloat and position. A part that is slightly wrong lets a component move, and that movement shows up as noise, wear or a leak somewhere else entirely.
Confirm the part against the parts breakdown for your pump, since several similar sizes are used across the range.

Frequently Asked Questions
Q: Can I use a standard hardware store equivalent?
Only if the grade and dimensions match exactly. In a bronze pump on seawater the material grade is the part that matters most.
Q: How many does the pump use?
That varies by model. Check the parts breakdown, and order a spare because these are the parts that go missing.
Q: Should anti-seize be used?
Where stainless threads into bronze, a suitable compound helps a great deal at the next service.
Q: Is it worth replacing hardware that still looks fine?
If it came out galled, stretched or pitted, replace it. If it came out clean, it can usually go back.
