I might have a slightly bigger jack someplace, but the 4 ton was all I could find in the basement where most of my tools and junk are. After thinking about it the 4 ton is probably the bigger one.
The other main question is about the ram end of the press. I am not sure what sort of profile I need to have on the business end.
I would go with an 8-10 ton jack as these wheel bearings can be a B#*#*ch. to break loose and the bearing usually explodes. At least here in the rust belt.
My press at home is made from the channel steel of a mobile home hitch.
Must commercial press use a plain large 1 1/4" or larger stud that uses slip over set screw attachments.
I have two large crates next to the press full of old shafts, bearing races, plates and shapes. All make good press tools.
