    Update:

    After dinner I went out to measure the radial play again. It was significantly less than before at the back bearing, about 6 microns instead of 16. So the bearing race must have finally...

    I had a closer look and now understand what Franz was saying.

    If you look at the end of the spindle you will see the square drive dogs. On the OD of those drive dogs is a separate small part, a...
