Schwinn Varsity Stem problem

So I went to a local bike shop to get my crank off and for some reason the guy decided to take the top bolt of the stem. As he was doing it the bottom of the bolt was rusted and got stuck inside the tubing. So now the fork is still attached because of a quarter inch piece of the bolt that is stuck in there. He told me to pour anti-freeze in there for a week and it will eat out the rust and i can take the fork out then. I dont know too much about bikes but I was wondering if there is anyway I can go about doing this in a shorter amount of time. I tried drilling it out but its pretty deep and I cant see a damn thing. Any suggestions???

If the bolt is broken off and you can get something that is a similiar diameter and longer as the bolt then I would try to spray a bunch of WD40 in there and whack the piece you are using for a punch with a hammer that may loosen it enough to get it out. Otherwise take the front wheel off and if there is a hole from the bottom take a piece of pipe that will fit in there and whack it from underneath. When you get it out take the pieces put them in a towel with a some good size rocks and whack that idiot in the head for messing with something he should have left alone

Is the stem still stuck in the fork or is just the wedge shaped nut stuck? If just the wedge shaped nut you should be able to remove the fork from the frame. With the stem and headset parts gone then you can look at how the wedge-nut is stuck. You can then determine the best way to "tap" the offender out of its hiding place.

If the stem is stuck, I'd use PB blaster (which, IMO, works better than WD-40) to soak the whole works for a few days applying at least once a day. Then with the wheel between the knees and the bars ends in both hands, wrench that beast off! Best of luck!

the stem is still stuck in the fork because the bolt broke off and is still applying the necessary pressure to keep the stem in. i will try your method. thanks for the tip

I would pull the top part of the bolt with the bolt head on it out of the stem. That should give you access to the broken off part of the bolt and the wedge. If you have a punch that is long enough, stick it down through the bolt hole in the stem to the broken off part of the bolt and drive it and the wedge down with blows from a heavy hammer. If you don't have a punch that is long enough, find a piece of steel round stock the same diameter as the bolt that is long enough to reach, and use it as a punch. Once you have driven the wedge down, you should be able to pull the stem out.
