Opps, bent a hyd cylinder today

This is the first time I have ever bent a hyd cylinder. I have broken a couple but today while trying to get a bucket load of dirt with my IH584 I bent one of the bucket cylinders. Thought I had gotten it straight enough to work and went for another bucket of dirt and got it dumped and then the bucket would not roll back up like it should. So now the left bucket cylinder is stuck half out half in and will not move so I can work on it more. Guess tomorrow I'll hook the cylinder up to a tree or other such thing and while backing away and working the hyd maybe I can get it all the way out so I can use my pipe bender to make it straight again
 
Good luck, it is just a matter of time before it gets straight. I just wish we could push the lever the other way and un bend it instanty. Jim
 
I have done it to less than .001" in 2' It just takes a good press and a feel for modulus of flexure. Jim
 
What bugs me on this is the fact it bent when I was doing something I have done hundreds of times In the past with other tractors. If I cannot make it straight enough to use I'll have to replace it which I do not really want to do. I thought I might have another cylinder off another loader but it is 3 inches longer so that will not work
 
I bent one a 276 Bi Directional, rolling out a bale. Done it 1000s of times, but that time I did something wrong.
I have never had much luck in straightening them. You can get them where they will work, might leak a little, but it seems that eventually they will bend again.
 
Once they have bent and been bent back, they will not be as strong. Once you have bent the steel you have taken it beyond its yield strength. Then you have to take beyond the yield strength again to straighten. The amount of lost strength is related to how much it was bent in the first place.

I am sure that Rich is good with the modulus of flexure, but I am not so sure about the turbo encapsulator or the pecunior vemblinator.
 
I was stuck on ice with the 504u, I stuck the pallet forks down and rolled it back,POW and then it went POW again. I looked around and everything looked good, till I tried to curl the forks back level. I had snapped the ends off of both cylinders. I had two weld on 3 point balls and I welded them on worked fine.
