Whoops, I didn't mean it that way. The PTO output is a 32t #25 sprocket with a versakey. It is bolted to a plate that is bolted to the ring gear. The only interface it has with the main shaft is a bearing it rides on to keep it centered. Basically, the PTO output is a "dead axle" sprocket, not a shaft (which I dislike but is hard to work around).
