So, from the “here’s an update on why there hasn’t been an update” department (otherwise known as the “I hate this already” department):
The struggle was real trying to get this swingarm apart. Initially I thought it would make good use of my hex wrench set I got for Christmas, but the fitting inside of the pivot point didn’t seem to be any standard size that I had. Good thing I got the metric set too, because none of them fit either. After trying a bunch of them it appeared the fitting was 11/32, but just as I was going to file a 3/8 wrench down I realized it was an optical illusion and the fitting was even bigger than 3/8”.
Found a hex wrench that fit, then discovered I didn’t need one anyway because all the fitting would do was spin in the frame. Turns out the whole thing is pressure fit, and is installed by tightening a bolt on one side into threads in the other side. The trick to getting it out is to remove the bolt, thread it in from the other side, then find a socket that fits the hole and beat the ever-loving snot out of it until it comes out. It’s all sorted now, but knowing how it went in would have helped the removal process.
