If its stubborn it probably has Locktite on the threads. Heating it with a heat gun will liquify the Locktite once it hits 650F. A soldering iron will work as well, just place the tip at the mating point of threads and nut and heat three areas around the dia.

I was wondering if those holes were for a special tool, like a set of snap ring pliers, but was in a hurry and did not have time to write a long post. I have a similar setup, although mine has never been that tight that I could not break it free with just my hand.
