My GC 2300 Massey Ferguson Tractor's front loader had a couple of leaking hydraulic cylinders. After buying seal kits from the local dealer (my gods they want a lot for 7 pieces of silicone rubber, $30 a kit!!) I went to work to fix them. The cylinders on this tractor were different than any I have dealt with in the past that have either a screw on end cap or a double sealing wire arrangement. I could find nothing about how to disassemble on the the 'net so it was figure it out time.
I contacted the dealer back via the phone and he sent me a image of the cylinders construction. So I decided to start at it. First off is to take out the allen screw from the side of the cylinder (see images). Then you have to use a drift pin to push the end gland into the cylinder exposing the retaining wire. Using a couple of flat end screw drivers I pried out the wire. After that it was pull out the rod to get at the piston and seals. I needed my impact wrench to remove the piston nut.
I did the first cylinder a couple of days ago and it took me several hours. The second one I just got done doing this morning at about a hours worth of labor.
BTW. I found the $2 HF "Mini pick and hook" set a big help with getting off the seals. The seal (blue seal in kit) inside the end cap was a trick to get back in though. I had to work it in carefully and maintain the correct side orientation. I suppose it would have helped if my fingers and old eyes were better.
I hope that this might help out someone else if facing doing this.
