Sorry for not updating, I did receive my endoscope but I was unable to find the source of the leak. I use my tractor to much in the summer time to warrant taking it apart. I am just going to add fluid as needed, at least thru the summer and fall. Come winter we will see how it goes. I am leery taking it apart not knowing for sure where the leak is. Numerous places it could be. 3 hard tubing lines tie into the pump, two flanges on the pump, at least 3 oil seals and I'm not sure just what else. I was unable to see very much of those places. Probably got the wrong endoscope. I do know it would be a major job. I'm pretty confident in the tear down and put back together but how sad I would be if I did all that and didn't fix the leak. Anyone with advice? I'm all ears!
