Steve, I’ve taken off a few of these hubs. My first try was on my 63 PV544 using a heavy duty three pronged puller. Of course it did not work.
So, I built a puller out of thick plate that bolted to the hub using the five stud nuts. I welded a piece of pipe to the plate with a one inch nut to the other end of the pipe. Then used about a 4 inch long 1” bolt. That did the trick.
Recently, I took apart a few badly rusted P210s and attempted to use my home built puller again, but even after heating and using an impact gun, the hubs would not separate after what must have been most likely 50 to 60 year of being stuck together. Then I realized that the puller I built had the 1 inch coarse thread and I could not exert enough force to pull the hub. So I built another puller with 1 inch fine thread bolt. Using the fine thread puller with an impact gun worked, but it still struggled.
I think if I had to do it over again, I would modify the setup to mount a small hydraulic jack instead of the screw.
So the short answer is that with sufficient force, they will come off, but you will need a very heavy duty puller. If you cannot make one, they are available but fairly pricy. I just could not justify the cost for very infrequent use.
If you are able to fabricate something, I would recommend you go the hydraulic jack method, but make it very strong and be very careful to protect yourself while pulling the hub.
