PTO Seal

I am in the process of replacing the seal(s) on the pto shaft. At the local bearing store, the counterman said that their suppliers no longer make a seal that is one-half inch thick and sold me two quarter-inch seals. Seems like a good idea, yes? Anyway, should I face the lip of the inner seal toward the tractor to seal oil in and face the lip of the outer one outward to ward off dirt?


The lip of the seal should face the inside of the housing, where the oil is. I am not sure you might not find an original seal from another supplier including several after-market suppliers and AGCO/MF. Using two seals should work.
