Well, don`t know what to say. It sort of fixed itself. Went out to tear it apart. For the sixth time I think. Thought I`d take some pics for you. Took the gearbox of the tower and loosened the nut on the top. Then I felt the spindle was ok
Just a little play, turned it and the play was gone. Couldn`t understand. Put the gearbox, I call it that because the it`s part of the gearbox but also holds the spindle back and the spacer on top and the nut. A very small amount of play was back. Tightened the nu a little. Less play. Tightened it a bit more. Gone. By this I have to deduce that it was a matter of tighteni g the nut just right but I don`t know. Have had it apart so many times now that I think I would have hit sweet spot a least one of those times. Waht else could it be? We`ll see if it holds. Put up a few pics; top bearing, bottom bearing and inside the gearbox.
