Once you take the clutch cable off you can spin the lever arm so the flat isn’t against that other lever thingy. I don’t know what these parts are called so it’s hard to verbalize, haha. But maybe I’m missing something like if the clutch cover is installed then the lever arm can’t be spun because it hits the frame or something. In that case then it wouldn’t be possible I don’t think.
After I replace the seal and reinstall everything I might just do a pretend seal replacement and see what happens.
