OK I tried to put it in a vise and knock it out but no go. So I applied a little heat to the shaft and pulled it out then.Once I got the shaft out I found that my wire has an "s" shaped bend where it is molded into the gear. There is no way I can place it back in the same way because for one thing the existing hole was damaged when I took it apart. So my next step is to #1 order new ones #2 place the gear in my lathe bore a 3/16 hole in the centre.Once that has been done I will make A jig to place the gear in to hold it centred then bore a 1/16 hole in the centre of my jig to feed the wire through. I will then bore a hole through the side and centre of the gear about 1/8 inch. At this point I will make my own "s" bend in my piano wire and place it in my jig then place the gear over my wire and into my jig. I will then mix some resin and ground up fibreglass cloth and force it into my gear filling all holes and air spaces then let it dry. One thing I didn't mention was to pam or vegtable spray the jig I mean soak it before applying any fibreglass resin.That should work but when you consider it's 6 bucks to buy a new drive wire I think that is a better way to go but you know I'm still going to try my repair idea just for fun.
