The "pin" is soft. I used a file to make it flush with the gear. Put a small punch just smaller than the pin on it. Supported with my vice and some rags and drove it out with a hammer. Replaced with a roll pin from the auto parts house. Came in a box with about a dozen different sizes. Just picked the best fit and pressed it in there. Mine was a bit long so used the angle grinder to get it close to the gear. Some room in there so no need to make it perfect. Was not to tough and worked just fine. Was the only way to get the shaft out of the housing any way. Roll pin does not need to be "peened" over. Spring tension will hold them in place.
