Picked up an old 1960 Massey Ferguson 85 Diesel. Tractor is very Nice and complete. The Roosa Master injection pump seized and took out the pump drive that runs off of the camshaft. I've got the pump ready to go but cant find that drive gear anywhere, Not even Ebay. Anyone have a line on one? I know its hard to find parts for these suckers but I didn't think it would be impossible. Engine is a Continental HD277, Also came in a MF88 and a Case 800 crawler
