This is a long shot, but I was replacing the o'ring seals for the lower control arms on a 706 Farmall. While cleaning out the last little bit of oil left in the rear of the tractor, I found what looked like the remains of a split ring retainer and two small pieces of copper. The ring looks/ looked to be about 1.25" ID and the copper pieces are each about the size of a grain of wheat. The PTO works ok, as near as I can tell; I don't use it anymore than two or three times a year, so it may not have gotten bad enough to show signs of failure yet. Any Ideas? This is the first I have tried to make anything other than cosmetic repairs to a farm tractor.
Thanks!
