X595 oil cooler behind oil filter

2003 X595 with 770 hrs. i see the oil cooler is leaking a little oil once in a while. i just bought this and hauled it 150 miles. I had a little puddle on the trailer when I got home and traced it to this cooler. M806798 is the part number and I've been told there isn't any in the country! Has anyone had any experience with this?
Thanks
Bruce

I see them on my go to John Deere site 287.00 dollars... You might only need the gasket for that and not the cooler itself....

Consider adapting another oil cooler. Online there are many small oil coolers. Most are simple in-out. Some have thermostat controls. Or put on an oil temp gauge for cheap to see if you really need a cooler.
