I have a hydraulic press and the press cup kit with all thread.
Using the threaded tool it just bound up under tons of load and wouldn't move, I didn't want to screw up the threads. I ended up using the cups from the kit in my press. But if you go too far you'll ruin that bearing and be out like $80 on a bearing. You have to slowly press it in until it stops against the end, essentially in just enough for the snap ring to engage, but if you begin to load up the bearing any little bit after it has contacted the stop it will deform it. Which is difficult to tell because I had to load it up with a ton of pressure in-order to get it to move. I screwed up one bearing getting it in, thankfully oriley warrantied it out. Even freezing it in my deep freeze over night didn't seem to help much.
I've seen videos of people doing this and it sure looked simple. But my cars almost always give me fits, especially our rusty ole 06.
