Very good tutorial. Saved me $200 in labor that probably would have done a shitty job anyways.
I have a few additions too.
If you happen to be on a farm in basically the middle of nowhere, like I was when I decided it was time for new seals, and everybody looks at your like your crazy when you ask if they have any metric hardware, 15/16 bolts have a head that measures 23.5 mm. I had the tools to weld them together, but I didn't want to waste this guys hardware so this is the solution I came up with
a little trick I read on another site recommended using your old seals on top of the new one while using the PVC pipe to tap them into place to protect the new seal from any rough edges the pipe might have. I did this and it worked great, even though the pipe didn't seem to leave any noticeable deformation on the old seals either.
