Hi All, first post. I have a 2007 JD 2520, 925 hours, with a fair amount of loader work. It's been developing a minor leak from the front of the transmission over time, but it no longer can be ignored, leaks only in forward.When I say leaks it was a drop or 2 a day, but is actively pumping out now in forward, I believe the Valve Block that houses the directional control forward valve has cracked or is porous. oil squirts out below the left side of the Charge pump. Problem is I just split and re assembled the tractor, I replaced the charge pump rings cause I thought the main ring around the pump was the culprit but not so. I can now see the leak seems to be vertically inline with the forward directional valve. Anyone heard of / seen this? The valve block is $2000 and only 3 spares in the world apparently. I did not see a crack on the block when I had it apart. UGH.
