NEU motor broken, how to measure, and locktite in motor screws?

I never had a muggy mount come back bent, but I have slowly increased thickness of all the mounts over the years as motors have gotten longer and heavier(1717, 1520, etc.). Your old mount is the black 7075 version - it is quite rugged, though not quite as rugged as the newer one of course. I would be surprised if it is bent, but anything is possible. :-)
