    Reman squareback alternator internal short?

    What do i use to drive the old bearing out and the new one in? Just a couple of appropriately sized sockets and a mallet? (I'm just guessing, I haven't even looked at it yet).

    Since there was no core required for the new alternator, I may try and repair this one and keep it as a spare. I've never changed one of these bearings before. Not even sure i have the right tools to do it.
