That is what I figured too. Out of pocket for me was about $40 per cylinder. AND all I had to do was drop them off and pick up later. Granted, it took about a week or so to get them back, as there was one seal they had to back order. But that was not a big deal for me...Would do it again without question. Especially since I do not have a good place to do the rebuild myself. Would like to though, as a learning experience.
But getting older, there are some things I do not really need to learn, and some things I need to relearn! But they are not tractor related...
As they say, the memory is the second thing to go!
Edit: I meant $40 over what it would have cost me to buy the seal kit from Kubota...
