Well, my gyre finally gave up and I pulled it apart to find the stator magnet has let go. Thankfully this is just a QT tank pump as the magnet split and rusted, but it’s been running with minimal issues for over a decade without trouble. Last checked it in March and I was in good shape.
Even the plastic on the wires gave up long ago, but this thing just kept kicking. Wish I could get parts!
