The speedo "bullet" that you are trying to pull out of the tcase just get stuck in there really good sometimes. If you can get some pliers or vicegrips on it (like in the pic above) and twist it and get it broke loose, you can usually work it out without destroying it. Use lots of wd-40/pb blaster/etc. to try to get it loosened up. If you can't get pliers or vicegrips to hold, you can sometimes take a sharp chisel and tap on the outside lip of the bullet and get it to break loose and spin, then you can put the pliers or vicegrips on and work it around and around and get it pulled out. Before you put it back in, puts lots of anti-sieze on it, that way it will come out easier, if you ever have to pull it out again.
