Hi. I replaced the wiring harness going through the stator tube to the control head. It has been a while since I took it apart, but I remember when I loosened the nut at the bottom of the tube, there was a small amount of liquid that ran out. I would estimate it to have only been a tablespoon or two. It was clear and seemed to be just water. Now that I am finally putting it back together I was wondering if maybe this was some kind of lubricant that I need to put back. If it is, what is it and how do I get it back in. Thanks in advance to whoever responds.
