I want to replace this seal on my 77. Do you have to disassemble the entire PTO housing and drive it out from the back toward the inside or do you pry it out the back and press the new one in from the outside?

Well I took it apart. It was a real bugger getting all the snap rings out.That seal does come out by prying it toward the back. There is a shoulder in the casting between the seal and the needle bearing. But I dont know how I could have gotten a hold of the edge of the seal if the PTO shaft had not been removed.
