So ..I finally got to take the charge pump off and see what was going on. There is some play to the input shaft when I wiggle it so it looks like the ball bushing has worn out. I've got a new lip seal ready to install and I have a needle bearing for the pump on order. I'm not holding out much hope for it to hold oil when I put it back together . There is not a lot of movement , Im getting about 1/128" max deflection of the shaft around where the seal is - it's not clear whether the bad ball bushing caused the seal to eventually fail or the movement is enough to cause a perfectly good seal to leak. Got another needle bearing on order before I put her back together and find out . I guess my only option is to split the tractor to get to that ball bushing out and replace it.
Thanks Tom
