PMD 4:1 brand new split

It's definitely a defect. Simply put, the milling process removed to much material around the boss. I wouldn't even try fixing it. Just be honest and show Ric the photos. I'm sure he'll take care of you.

Welding or JB weld is not going to be the answer. Even if you do pull that off, the shaft alignment could easily be off, and that will cause other problems.

I'm gona stick my neck out here and my $.02 now that I see better pics I see a small design flaw. To much material is removed from the bearing bore on the out side of the case . could be fixed real easy withe a simple tool change in the machining process with a .125" radi around the bearing bore or don't go so deep on the counter bore . I wouldn't trust any glues or welding in that area it's to critical for alignment . send for a replacement .

I'm pretty sure that welding it would just warp the bearing bore and it would no longer fit without remachining it. Much easier to get a new piece in my opinion.
