So I've followed all the help in the search function but it just won't budge. Am I doing something wrong as I don't think it should be that tight
I unscrewed the nut back which came loose quite easily. I then held the screw thread further up with some vice grips and tried to twist the end with some grips but it just won't budge.
I assume this is the part that gets screwed up and down the shaft then you tighten the nut up after adjustment?
It doesn't look like its been pressed on etc to stop it being moved. What do you think?
