The last one I did was many years ago, but it seems like I had to get creative when the new parts took up a lot less room than what I removed. The new bearing and seal parts were nothing like what originally came on my PTO shaft. I had a bunch of questions like: Does the new seal go on the outside, so the bearing gets lubrication from the sump? Does the new seal lip face the outside or inside? The original assembly put the seal on the inside of the bearing. Looking at the replacement parts, I decided the new bearing would be happiest with the seal on the outside with the lip facing inside, where the lubrication is. If I remember right, it was definitely possible to assemble everything with the PTO shaft too far out or in from the bearing retainer housing. Fortunately, I had another shaft I could measure, since I took the leaky/loose one apart without measuring anything.
No, I wouldn't grind on the ORC to get clearance.
