(new to the list and not working with the interface well! This may be a duplicate post, sorry)
I just pulled my 1st gen PH rear hub apart for a rebuild. Without access to a press or pullers, I made up a home-built puller to remove the left side endcap and then just tapped out the right side endcap with a rod through the inside. I should have used a brass rod but I was too lazy to look for my brass so I used a long bolt and a gentle hammer.
This sequence of disassembly leaves the bearings in place in the shell. If you've removed the axle and bearings as a unit, the homebuilt puller can be used to pull the left cap off the bearing giving you access to the inside of the right cap which can then be tapped out of the bearing. Of course, support the inner race of the bearing if you care about preserving the races and balls.
The puller is about the ugliest piece of tooling there is. It works quite well. It's free to anyone who wants; I'll make another one in 2042 when the new bearings fail.
