Are you flushing the entire system or just draining old ant-freeze and replacing with new? The PH factor may or may not be true but know too that salesmen will say anything to get you to buy their product. Charles Sorenson, Ford's RH man adviser for forty years, despised Harry Ferguson and once said, "...had I foreseen the consequences of that meeting [with Ferguson] I would have avoided it!" Sorenson also said, "Harry Ferguson could sell you the birds off the trees". Sorenson's opinion of Ferguson was that he wasn't schooled in engineering, but was simply a shrewd businessman. Ferguson held patents on the 9N tractor, foremost was the 3-PT Draft Control System in his name despite the fact that he was not the inventor. The 3-PT Draft Control Hydraulic System was the invention of Ferguson's real engineers, Archie Greer, Willie Sands, and John Chambers. Ferguson merely applied for the patent (and several other 9N parts)on the draft control system because Henry Ford didn't believe in patents and despised lawyers even more ever since his lawsuit (which Ford won) regarding the Selmer Patent over his Model T automobile. FORD engineers designed much of the 9N tractor and the patents went to Ferguson despite this.
