I had three hydraulic cylinders decided to leak just sitting in cold pole barn. I'm thinking it may be a cold weather shrinkage problem, O-rings shrank. One of the cylinders was difficult to get apart. Someone had turned the end too far and pulled the wire all the way inside. I drilled the hole out a little larger, then used a smaller bit and drilled the backside of wire so when I turned the end, the wire decided to come out, THANK GOD!
I made a spanner tool using an old plumbing wrench. I also use a brake hone to clean up the end of cylinder. I find it easier to leave cylinder on tractor, saves removing hoses, just pull the rod and piston out.
I've concluded, if a hydraulic cylinder doesn't leak today, just wait it will leak tomorrow. I think I've rebuilt atleast a dozen so far.
