    Update - finally remembered I had a pair of tongue and groove piers with leather glued over the business end. Carefully tried lefty loosie but seemed to shift a fraction and stiffen so I tried reverse thread undo and it worked. Surprisingly the ball seems permanently fixed to the shaft (unlike as shown on the parts diagram) and the shaft with the square sides at the bottom actually screws onto the motor shaft. Even more surprisingly, the hex nut that I thought would be the primary nut for holding the burr bracket on the motor shaft is just a spacer and has no thread.
    Have now removed the bottom plastic casing and noticed the critters have been dropping pupae and their own dead bodies all over the internal electrics (plus a few cockroach eggs to boost) so I won't sleep well until I have torn it down and cleaned it well. Will tackle some more this weekend.

    Per its parts diagram it appears to be a separate part.

    Ah yes, that thought has crossed my mind. Another reason for my reluctance to apply leverage without knowing which way to turn it.

    Not to date. It needs some leverage as it has been 10 or even 20 years since it was last removed. Trouble is, once I apply leverage, I may break it if trying to unscrew the wrong piece.

    It is hard to get any spanners on to them as they are sitting at the bottom the the well. That is why I suspect the ball must come off so a socket can go over the hex nut. But whether the ball and square section are permanently joined or whether the ball screws onto a thread arising from the square section, I have no idea.

    Trouble is the ball is just below the rim so hard to get a grip on it. On the previous MD6 thread I wonder if the square section came off with the nut?

    Not as clear though. Back to my original post, any ideas on how to remove the black ball from the shaft?
