It's not really a press. Just looks like any other puller except the main shaft is much thicker and you just wind a little screw on the centre. I doubt it would be more than 5 tonne.

What really helps is using bearing puller jaws behind the blade boss. The type that comes in two halves with heavy bolts that lock it together. It's mainly used in a press so you can push a bearing or gear off a shaft. Much better than those 3 jawed things.

Perhaps you could do it in your press. Have to find a way of getting the whole engine in Weld up something really heavy that would fit across there. Would have to be a very big press wouldn't it ?

All this not really worth for a Briggs is it?
