[TowerTalk] Rohn Trust Bearing

I have a pair of Rohn thrust bearings in the top of my tower. The set screws
have rusted and the tower guy told me that he couldn't unscrew them. I am
going to have to remove those set screws so that I can take the 20' mast out
of the top of the tower. The mast is currently sitting on a HAMM rotator and
the bottom thrust bearing is about 12" above the rotator and about 5 feet
down in the tower. The top thrust bearing is mounted on the top of the
tower. (120 feet of Rohn 25)
Since I don't seem to be able to unscrew those set screws, what are my
options? I suppose I could have him drill them out. Probably need to replace
the thrust bearings anyway.
Anybody had this problem?
