full disclosure - that works. here is my arbor press setup complete with cheater bar. It’s a one ton. once I extend the bar I can easily double that.
You haven’t lived until you have bent a pipe wrench. Lol
This was from on a machine I worked on a few years ago. I forget why we were breaking the coupling apart. I know the guy that was working on it never used these wrenches before. I know on other machines similar to this one, we had hell getting them apart.
They’re shaped like piston rods. The second photo has a transverse round cheater bar sticking out towards the camera.
That part is actually a drawbar. One side is a 6 point, 3" I think if I remember right. The other is 12 point, same size. We use an impact to drive the drawbar & break it loose.
Enough leverage there to twist off the bolt. Oopsy…
