    Default B1630 loader leaking bucket cylinder

    One of my bucket cylinders is leaking. I was using my tooth bar with the teeth straight down, just touching the ground clearing some brush when I hit a root and one of the bucket cylinders blew. A cloud of Hydraulic fluid burst from the cylinder. I believe I blew it with an impulse. Ok, so I got 2 seal kits from my kubota dealer and replace the seals on both bucket cylinders. Thinking all was well I fired it up and to my surprise the leak was still there. The other cylinder is still fine and does not leak so i believe i did not damage the new seals when i installed the head gland. The leak is not from the front wiper or rod seal it is coming from between the head gland and the cylinder barrel where they meet. The head gland is pushed in the end of the barrel and seals with an o-ring and is held in place by a retaining wire installed through a hole. I don't know maybe I damaged the seal but if that was the case why is it the same cylinder that leaks, was I just lucky on the other one. I am thinking that I have a cracked head gland or cylinder barrel. Does this sound possible? Has anyone ever had this problem that was not fixed with a new seal kit. I put in a couple of pictures of the end of the cylinder. The arrow points to the hole where the retaining wire is installed and the fluid leaks from there or around the space between the head gland or barrel.

    You need to pull it down again and inspect the parts very carefully, hopefully it is just the O-ring.

    You are also lucky you did not bend both rods with that technique you used-it's very easy to do with the bucket straight down like you had it.

    Thanks, I was hoping that was what someone would suggest. I am going out to do that now.

    Just got finished replacing the o-ring seal a second time and it still leaks like before. I checked the end of the barrel for any reason for damaging the o-ring before i put it in and even touched it up with emery cloth for good measure just in case. It all appears ok. I was very gentle when i put the head gland back in, and it seemed to go in smoothly. When I removed the gland before replacing it a second time the o-ring had alot of damage after removal, but i think i'm getting the damage when it passes the retainer slot upon removal. I was thinking of swapping the gland to the other side but I risk damaging the seals everytime I take it apart and don't really want to have to replace parts on the other cylinder i just renewed the seals on. what would you guys do? maybe I just need to take the cylinder in and have it looked at before i dump to much money into this problem. I seem to be getting nowhere. Thanks

    Technically yes, it should be there.

    That's a bummer for sure...not sure the best way to proceed at this point I was hoping (like you I am sure) it was just a cut O-ring.

    Thanks Kennyd, I decided to just start a new thread in the hydraulics forum. Just pasted in my first two entries. I have been working on this for 2 days trying everything i can think of. I even tried a fourth o-ring of larger diameter but of smaller o.d. when stretched onto the gland it stood slightly more proud of the gland surface and I was still able to get it to slide into the barrel making an extra tight fit. I then removed it and it still looked ok. so I assembled it and tried it and it still leaked. AAhhh. I also swapped the fitting on the gland with the one from the other side just in case it was leaking and running down from the top of the cylinder and appearing to come from the slot between the gland and the barrel. It still leaks. It is hard to see exactly where it is coming from. top of slot or bottom because by the time i run to the front of the tractor after operating the valve everything is covered in oil.
