I was measuring the main journals with a micrometer. These were the measurements I got from the mains
1)2.2994"
2)2.2994"
3)2.2996"
4)2.2994"
5)2.2995"
6)2.2997"
7)2.2996"

Then I set my micrometer to 2.3000" and calibrated my bore gauge from that and measured the assembled bearings with the bore gauge and got.
1)2.3010"
2)2.3010"
3)2.3010"
4)2.3010"
5)2.3020"
6)2.3001"
7)2.3010"

Giving clearances of
1).0016"
2).0016"
3).0014"
4).0016"
5).0025"
6).0004"
7).0014"

Even if the micrometer isn't exact, the measurements of the bores were relative to the micrometer anyway so the clearances are correct.

I made the stupid mistake of ONLY measuring the main bores with the bearings in there so I can't tell you what the actual bore is. If I knew that then I could know if it was a bad bearing or not.

Regardless, I know what to ask the shop to do and then what to measure and look for once it's back from the shop and I'm assembling it.
