Hope this is a help.
Thanks Randyjawa; I forgot to mention that in my post. Most, BUT NOT ALL, stems if factory will not have an issue with this problem, but your right because it can and does happen.
If the poster doesn't already know this, when you loosen the stem bolt you need to put a block of wood on top of the bolt before lightly tapping it with a hammer to knock it free. Or use a rubber mallet. Don't hit it too hard or you could end up again unable to pull the stem out due to the wedge getting jammed. The stem bolt will drop about 1/8th to 1/4th of an inch when it frees up.
