Great advice on the bearings, thanks.

I am trying to re-install the stem and the crank, and have a couple questions regarding them:

How do I get the bearing cups back in? I was able to get them out using a hammer and screwdriver, but I don't think that will work so well in reverse.


For the crank, I'm not sure what they are called, but they screw into the bike and hold the crank bolt in place. Any advice on getting those back in? I'm trying to do it but I'm worried that I'll strip the threads. (Proper names would be good too; I promise I'll use them if I know them)

Thanks so much for the help.

UPDATE: Got it! Needed some tools (headset press, anyone?) that I simply didn't have. The LBS took care of it for me.
