For what its worth – I’ve seen two other 4425’s with the same problem. That casting is kinda thin in spots and seems prone to fracturing. My Dad’s 4425 had this problem, he found it that way in the 1960’s. at the time he just put it back together the way it was and ran the thing. It ran for years like that. In fact, it still is that way, I’ve never fixed it either, and I’ve known about it since 1991. Finding a second motor with exactly the same break on the same part made me think it could be a chronic problem. Now that you’re reporting the same type of failure, I’m migrating from thinking to believing. I didn’t fix the second one either…. and not because the part is not available, because I’ve got an NOS bearing carrier sitting on my desk not a foot and a half away….. just don’t feel like using it…. yet
