I didn't realize it had been that long since mine went out. I am still on the gear I had made. Working perfectly (knock on wood). I still have my spare but it is without the center hole. I might be interested in one if it were cheap enough. The machine shop I used had to hand carve the gears and it was pretty expensive. They made the center hole by heating up the shaft and pushing it thorough the gear.
