There is a lot more to rebuilding the couplers than meets the eye, and some of those things have been mentioned here. I have been working on some pictures and ways to have better success re-sealing the couplers, one includes a different barrel,or sleeve seal/backing ring, the spring and latch are important as mentioned, and also re-shaping the rear end of the sleeve, over time this area gets smacked with every from a hammer to a hitch pin to get it to move rearward so a hose can be installed, this makes a sharp over sized end that needs smoothed down so it don"t cut the new seals as it is pushed back into place.I plan on submitting these ideas and pictures to Green Magazine soon, although it may not coincide with the article they had about this a few months ago.. Deere couplers have a lot to be desired, and a lot of them are leaking as we speak,,Deere tried to fix the problem by trying to catch and send the "leak" back to sump, or even on to the ground via a drain line. I have came up with a quad ring that has 2 sealing surfaces on the inner surface, along with a solid backing ring, these work much better. One problem that happens when going back together is the end of the spiral backing ring ends up lipping over the o-ring, this lets oil flow over and past a good o-ring, the solid backing ring that I use keeps this from happening. I will post some pics and more of my thoughts latter to share with some of the ideas that others have mention on here.

Although he himself has never actually owned or restored a tractor, he was always enthusiastic and always around helping with other peoples projects.
