Here are some pictures of the tool to install the seal. I made it out of 6. 5" 6061 aluminum. That was a lot of whittling ! I filled a large trash can up with chips. . The ring is for centering the seal retainer. It could also be used as a poor mans driver. It was made out of 1018 steel. My camera man almost has the video's done. I will post them when they are done.
