man listen up, if that bearing does not spin easy at all, change it out, figure out first if the weld is coming in contact, if so i would take it back to him, tell him whats up, he will have to pull that bearing off anyway to fix the weld, and have a new bearing put back on it, you have it all apart so do it right man, looking over something like that can cause big problems you do not want, that crank is spinning like fuck at wot..
