Hello LBillesberger, I can recall doing some rebuilding on some bronze bearing inserts a number of years ago and using silicon bronze tig rod. Unfortunately I can't remember the specific grade or the exact filler identification. Most likely though Bohler, UTP, Eutectic and some of the other specialty companies can probably provide you with some ideas for a compatible repair material. I will be interested to hear from some of the other posters and hear how you came out. Good luck and regards, aevald
