The drive motors have a plate held on to the bottoom with small machine screws where oil is leaking from in a small stream. New Holland parts dont seem to show a motor breakdown so I can't see what this plate holds in. These are visible thru the mounting bolt access hole in the belly pan. Only one screw is accessible so I drilled a 1/2 inch hole to take out the second screw. Any ideas if the parts under this plate can be pulled out and an O ring replaced or would that be too simple. It looks like the end of a U joint cup under the plate and it is loose wnough to wiggle a bit but a bit afraid to try harder getting it out for fear of what all might follow.
