I really need to replace my worn out idler/clamp part on the hot end however I cannot seem to remove the screw/bolt it pivots on. See pic here: https://www.dropbox.com/s/kphmnfwqkwwlqee/2014-04-23%2021.23.38.jpg
I can see the other end of the bolt turning however it only comes out a few mm then just turns freely. I have put an excessive amount of force on it to no avail. I am almost wondering if there is a hidden captured nut that is on the end of the bolt keeping it from pulling through?
