What did I do wrong?

Thanks for all the responses!

I pressed the old bearing off the 4.56 gear and checked dimensions on it, the setup up bearing, the new one I put on with heat/freeze and the 2nd new one I ordered to replace the first one I had to remove. No more than 001 difference. The new and set-up are all koyo HM803149N, the original is a Bower.

With my shim stack now at 084 and here is the pattern (not as good as 094 IMO). Notice the marks on the carrier were it hit at 094. I checked distance between the pinion head and carrier with the 084 stack and have about 015 in clearance. Hard to check but I was a using a feeler gauge then confirmed it with my calipers. It seems tight to me and honestly I would not have ever checked it had this not happened so I do not know what a safe distance is!
