Hello D, Thanks a bunch for the response. Yeah, it's easy to take stuff apart, but getting it back together, not so much. Actually, there are two larger ball bearing balls, and I THINK they go on that little rocker inside the actual pump, but the third, and smaller one is a big question. It would be great if you could dismantle, and maybe send a photo. Thanks, FABO, A GOOD PLACE TO BE. Old Dart 66
