I don't think they are made to take apart easily, and that is not an
easy job. It's like some kind of puzzle, and comes apart and goes back
together only in a certain order.
To be fair, that's true of most machinery - unless you like your pistons
outside your engine.

But it's usually obvious how to take something apart except for
modern things where they hide screws.
The Simplex jack has a nameplate that is held on by a rivet that
becomes curved when hammered in. It's impossible to pull the rivet out
withot breaking it. I've replaced that with a screw.
Then the two bearings are pressed in from each side and it needs a
thin wedge to start getting them out, then a pin punch.
All of the split pins are in such tight places that I needed to cut
them in half to remove them.
There's about half a down places where a trick is needed to take it
apart. That's something I've seen only in modern equipment.

If you have lifetime sealed bearings, there is no need to make provision
for disassembly with hand tools.

And more and more stuff has been made this way.
