I can do up a basic procedure since I looked at the KR WILSON tool on page 3 of their catalog, took a new dust seal and a drag link, then reversed engineered the installation tool myself as I did not have an actual tool to copy, so did my best to replicate it. I drew it up the old fashioned way - on paper, NOT using Auto Cad, then processed it the way I would normally process a job for CNC Manufacturing. I wrote the process sheet, wrote the CNC G-Code Program, set up the CNC Lathe, and ran the parts myself in two operations. I turned the head end first then set up the second operation to turn the shaft end complete with a knurling tool to better grip it with -just like the original shows. Now, I programmed little .01 radius corners breaks, a common CNC machining practice, and small chamfers as needed along with an undercut in the counterbore where the seal base sets into so as to prevent any improper alignment. There needs to be a drilled hole in the center of the recess to clear the drag link threaded end too. The entire CNC set up and program itself I can make available but one could make these on a manual engine lathe if they are a turning pro and have all the correct tools to do so. The knurling tool I suppose could be optional, but after first trying to install a new dust seal using a large socket, I concluded it was a PITA to hang onto with one hand while trying to keep aligned and from boogerin' up the seal. I practiced with an old seal first. This is a tool that one would need to use maybe one or two times in the life of their tractor, heck when I did mine for my 8N, it still had the original leather rear dust seals on it! that is why I offered to make it available to anyone wanting to rent it out. I'll see what I can do to do a HOW-TO's write up...
