Please see pic. I had a front disc conversion done on my 39. Today I noticed that I can’t get the grease gun on the zert. I need to remove this nut in order to put a new 90 degree zert fitting on.

The dumb question is, I have heard of nuts which you can only tighten on once. Since the nut looks different, I figured I better ask. Can I remove this?
