Just spent 14 hours on a boiler feed pump that should have taken three
It was a simple bearing swap on a big vertical feed pump at the plant. The old bearing came out fine, but the new one would not seat. We tried heating the housing, freezing the bearing, and every puller in the shop. Turns out, the housing had a tiny, almost invisible burr from the last install. A quick hit with a fine stone and it slid right in. That burr cost us a whole shift and a lot of frustration. Anyone else had a simple job blown up by something you couldn't see at first?

Gotta disagree a bit there. That hidden burr is exactly what the pre-check is for. Running a finger or a stone around the bore should be step one, not step ten after the fight. Those lost hours are on the process, not the part.
