I made one a few years ago , to take out the king pins in Magirus Deutz 8 wheeler steering axles . . Needed 100 tonnes (yes!) I used a Hydraulic pile driver ram ,6", bore that I scrounged from a "Hush Kit" when it was finished with outside a hospital . I used very heavy cross section channel and "H" section for the frame . I had an electric motor and hydraulic pump from a factory scrapping a big machine . . I think it will have about a metre travel and something like a square metre "work space " . We finished with the "maggies" a few years back , but the press is still here , it isn't eating anything , and it's always there if needed . In fact we had a chap from a local company came along and said "we haven't anything this heavy , can you press this out for us ! " I have a photo somewhere , if I can find it I'll post it .

14 tonne logsplitter off tractor hydraulics doubles as a press here.

Once you press above 20T, your into squeaky bum territory.

We do it inside a tyre . It starts to generate pressure , and then everything goes quiet . When it goes it goes with a bang .

30 tonnes to shift an old Ifor hub bearing.

Excrement!

I managed to shatter a tractor half shaft bearing few weeks ago, was a tight fit but managed to hammer two offcuts of angle iron behind it but they must of been putting slightly more pressure on the outside race! Should of warmed it up first!!!

Local place here has a 400 t press , but that won't do furrow press rings

What is the trick to getting press rings off a shaft?

Not sure there is one,,,,luck plays a big part soaking it in the burn or pressure washer helps but tbh I’ve tried but most rings cracked by the time I got them off, the Lemken press rings are the best idea and work well too

Many years ago I visited a local engineers to press a drive hub off a Tasker spreader hydraulic motor, the key was half sheared.

At 15 tons (without movement) the guy operating the press put a bag over it, and said from here onwards you can operate the press.

It shifted at 20 tons, when I looked round, their wasn't a soul to be seen

I've a little 10 ton press and that scares me enough!

Sounds like the problem with some of these presses is they aren't built solidly enough. The rigider they are, the less energy they store like a spring for a given force and the less they go bang when the siezed parts finally give.

A lot of these smaller cheap presses will be built strong enough not to break, but are still not as sturdily built as they could be and still flex quite a bit.
