Got the bolt out. I think big john said it would twist with my fingers and he was right.
The pinch bolts on the crank didn’t feel all that tight. On the arm it states they should be at 12nm-14nm. I am not an expert but it didn’t take any effort for me to loosen them at all. I hope that’s the issue.
Trying to get the arm off as we speak. I have a rubber mallet and I am tapping the arm. It has moved a little bit but not enough for me to remove it yet.
