Rivets are OK... problem is a bad pot that has some intermittent areas.
I bought my 5400 used, and the previous owner had mounted the azimuth rotor UPSIDE DOWN (no wonder it "turned the wrong way"...) and it got a LOT of water inside. Despite my best efforts, the AZ pot has continued to go downhill ever since.
Needs a brake disc, too...

I'm throwing this out for what it may be worth...
I now have two 5500's and have had no trouble for years.
Before that I had two 5400's and had trouble with both on the pots...the connections were rivets, and I opened up both and soldered the rivets, solved the problems on both...
I replaced them, still working because of the over 360° rotation on the 5500's..
May be worth a shot to take a look....
