The loader valve on my '79 L295DT (factory loader) has been weeping for a long time and is now finally peeing fluid out the side whenever the tractor is running. At the very least it probably needs every seal replaced, etc... I am not very experienced with hydraulic systems so I'm not sure that I would attempt a rebuild myself even if its possible. Right now I'm just trying to determine whether or not a rebuild kit would even be available for something this old and/or a new valve. If neither is available are there aftermarket replacements, etc...?
