" but the telling story was the tensioner pully. It was a Dayco. Now I know that is not an OEM part which tells me that it had been changed out early. I bought the truck with 36K on it, so at somepoint it was replaced."
On Page one I mentioned this "Cummins tensioner is made by Dayco. Looked at the part on Geno's Garage."
so the one you just removed was OE, look on the back side it has a CUMMINS #.
