Does anybody know if there is a seal repair kit available for the steering controller in my L4300DT? Its leaking out the dust seal - a lot. The WSM shows how to open it up and replace the seals but I can't seem to find the parts on the Kubota parts website. The controller is a TA040-37002 and it fits about 40 different L models, surely there are repair parts available somewhere. If they expect me to drop over $1100 for a new controller just to fix a leak I'm not going to be very happy.
