Did you find both snap rings that hold the inner primary bearing? There is one on each side of that bearing. Previous owner forgot to install one??? Just guessing.
First, it's an aftermarket inner and outer primary which are notorious for being "off" just enough to cause all kinds of issues, though Custom Chrome stuff used to be decent for the most part and factory stuff can be hard to find.
Second and most importantly, it's a supposedly "upgraded" wider bearing that eliminates the inner race pressed on the main shaft. It's too wide for the housing and requires ommiting the the outer lock ring. So the outer lock was never there. As to why it walked and whatever other failures occurred, I'm thinking bearing failure but that's just a guess.
Yet another victim of marketing techniques, falling prey to beliefs of improvements (upgrades) over the factory engineering. Not picking on you Greenhawk because I know this is gonna cost a lot to get back together. But when you go back with it, use the correct factory type inner bearing and race...

Thanks for pointing that out....Good eye Rufus. I had one of those "wider double row" bearings in mine for about 500 miles. Glad its gone (back to the stock setup). OP, sorry for your bad luck but (I suppose it could have been worse.

So I have another inner primary for forward controls (I believe it is a Custom Chrome item - bought prior to 2010) that I plan on taking to a machine shop to machine the holes (1 tapped) for mid controls. There was a thread I had seen on here where a forum member machined/drilled & tapped their own. Doesn't seem to be a difficult job for a machine shop. They're charging me $80.
Searching online I found other inner primaries for mid controls and they were mostly around $350 and one I found for $250. I did see one for a 2000-2006 Dyna (#60681-01) for $198, but am not 100% sure it would fit a 97 Dyna.
So the $80 machine shop apparently didn't have the correct tools/tooling to do the job. The recommended one started talking and then verbally said it would cost $200-$250, so not going that route. Probably getting an OEM one online. I do remember a member here who drilled their inner primary and it worked for them, just not sure in my ability to do that.
