Hydraulic Cylinder Rod is Stuck and Bend Due to the Hitting of Heavy Stone | Check How it's repaired

I explain how to check the straightness of a hydraulic cylinder rod and calculate allowable run-out. This is an essential task when repairing any hydraulic cylinder, because if a bent rod gets put back in, the life of the rod seal(s) is compromised and the cost of the repair largely wasted. I also explain that bent rods can, in many cases, be successfully straightened and re-used. Provided they can be straightened to within the allowable tolerance. One of our members who works for a cylinder repair company, sent me his counter position on this: “In our experience, 'straightened' rods are never really straight. They almost always have an S curve in them after straightening has been attempted - because they do not re-bend in the same place they originally bent. Using these bent 'straightened' rods greatly compromises the column strength of the cylinder, and is unsafe for a heavily loaded cylinder. It also wears unevenly on the gland and rod bearing, and frequently doesn't
