- We cut a window into the side of a hydraulic Rock Grab Cylinder to see why it would extend but not retract.
The failure Failure Analysis shows that the Piston Nut came loose and eventually stripped out the threads in the rod end and jammed the two piece Piston, seals and Nut at the bottom of the barrel.

Most home owners don’t have tools to properly tighten the nut
They will come loose if not properly torqued and lock tight on treads
I agree Phillip, with that being said I am not sure what happened here I think that the cylinder was over loaded and the nut holding the piston on stripped out the thread.
You cut the cylinder open ? And it's the seals and the nut piston ? you ruined the cylinder there is no way the seals or the nut coming loose would not allow the shaft to be locked in one spot.
John, if you watch till the end of the video, the rod was slightly bent as well, causing massive internal stresses that did not allow us to even loosen the gland nut.
Please mine teacher
