Hey Dave
Well the whole thing ain't yet back together and water-tested, maybe you want to wait for someone more experienced to post, lol.
Seems like a decent amount of local appliance parts places locally have those tools, you should call around Cinci. Removal was simple and straight-forward, once you saw the tool for it. Then I got a pail of grease cutter and some clean rags, hot water, and shoved the rags down the center post with a plastic pipe, cleaned it out well. Feel inside the top and bottom of the post so you know where the bearings and seals are supposed to seat, since my tool came with about 3 different mandrels(diff lengths) to cover quite a few WP/KM length of center posts. And my kit came with extra seals for various styles too. Top bearing(with some turbine oil coating it) goes in with a seal cup washer below it, bottom one goes in lone, with that long tool cranking from both sides until it all seats on a metal ledge. Now you're done with the installer tool. Then you easily place the seal cup under the bottom bearing by hand, and the final top bearing on top of the upper bearing. You'll see splines in the outer edge of the bearing, place more turbine oil down those spots to fill the cups.
So for my 59-60 WP, bottom has tool installed bearing then hand-installed cup seal, top has tool-installed cup seal and bearing, hand-installed top seal cup. I'll get a few more pics tomorrow.
