John, I bought one of those and played around with it to see what the best possible scenario might be. I took your stepped pin and turned it around and pressed against a pin from a roller bearing. The gear came right off. I don’t know how it even worked for you the other way. The step is too large on the OD and not long enough.
The press is towards the bottom 1/8” of the gear. This will allow you to insert a pin that is too big. The pin always gets stuck at the end.
I did taper the end of my pin by inserting it in a drill and honing it down at the end. (I know you don’t have machine tools)
Anyway, I hope this helps you and the OP. This is a nice little puller!
