Hi there,
I recently aquired a 1952 Massey ferguson tractor, 2wd, gas engine. There is a valve on top of the transmission housing that leaks oil when in a certain position. The valve when pushed in allows flow to the hydraulics that run the FEL. When the valve is pulled to its other position the height of the 3pt hitch can be set but oil leaks out between the sliding potion of the valve and the cast piece. I replaced the o-rings in the valve with the closest ones I could find but the leak is still present. I don't see any scratches in the valve bore.
When looking for this part online to try and source the proper O-rings I didn't have much luck. One manual I stumbled upon called
It a "bypass plate" and it appeared to be just a plate without a valve and a threaded port like mine has. Perhaps it is an aftermarket part that was added with the FEL; not sure.
The 3pt hitch also leaks down when the tractor is or isn't running. Is this a common problem and if so what's the best fix?
Thanks[/img]
