Step four (the first step four, there are two step fours on page 24 of document L-55) says to simply "Complete the removal of the basket by loosening the spanner nut on the spintube and expand the drive block with a wide bladed screw driver. (fig 58)"
Now, I can see the place where I expand the drive block, so I can only assume that the spanner nut is the round bit with four notches each 90 degrees apart. It doesn't look like the drawing though. Anyway, this thing does not want to move. I'm trying hammer/scredriver vs nut and also pipe wrench vs nut. Is it reverse-threaded maybe? Seems like they would have said as much, but it doesn't really go into detail as to how one is supposed to "loosen the spanner nut".
I should mention that this machine is quite a number of years old (the serial number indicates it was manufactured in year "J", whatever that means)
Am I more likely to bust the inner tub trying to get this spanner nut off, or am I just missing something?
