Man this is simple - all it takes is a vise and a small socket from a socket set. Put the socket over the pin on one side and then put this in the vise - you're going to use the vise to push the pin out into the socket on the other side.

Takes longer to explain that it does to do it - just make sure everything stays square so youdon't enlarge the hole so it will still be tight when you reverse the process and push a new pin in. Just happen to have pic -



It takes a little care to get new pin lined up and started squarely, but its not that hard. When you own UE SM you learn stuff like this so you can keep running, lol!!
