This pump was removed from a Ford 1510 tractor. It was on a Shibarua K773 engine. I have never heard the tractor run, I bought it in a non-running condition with spun rod bearings. It last ran about 5 years ago from what I understand. I have no reason to believe that this pump is not 100% usable, but since I’ve not heard it run, I’m selling it as is/for parts. I am parting out the entire tractor. If there is a specific piece you’re looking for, let me know and I will list.
