bc said: (quoted from post at 09:46:18 07/23/09) If it is leaking under pressure, there is a 1600# popoff valve in the right front (facing the front of tractor) corner under the plate. Could be an oring or something leaking with the rockshafts, cylinder but you would notice something in their operation. I had a piece of metal underneath the ball on my popoff on my 2606 holding it open but it kept the pressure released so fluid just bubbled out. There is a drain tube in the right rear that could be plugged up. There is also a 3" long bullplug on the left front that could be removed to help it drain better and not keep so much fluid in it. If your drain tube is a screw in (my 2606 is welded), then you could screw it out and replace it with a 1" nipple or so.
Let us know what you find when you remove the seat and plate. Be careful when removing the plate to try to save the gasket with a putty knife. It may be saveable once you find your problem and then use a little hi tack and a little blue form a gasket to help seal it or just use form a gasket without it.
Once you open it up, you should be able to run it (with all safety precautions) to find your problem. There will probably be a bunch of sludge in the bottom.
Unfortunately this is referring to a 666 and smaller tractors.
The 766 is like the larger tractors and does not have a hydraulic reservoir under the seat. You need to find just where the oil leaks from and change that gasket or O-ring.
The vent for the system is built into the dip stick used to check the oil level.
