Does anyone knpw at what temp. you ruin the steel? Probably a loaded question. My thrust bearing rusted enough over the winter I decided to change it. Last time I put the shaft in the freezer overnight. Then put the bearing in the oven for a couple of hours....and she dropped on the shaft slicker than goose shit. I just don't want to hurt the bearing. Would 400-500 degrees hurt anything here? Yes I know I could have it pressed on...that would likely cost me a 12-er or 2...I am on a budget here.
