In all truth I do not know. My pump is a new pump, but it has been so long since I installed it... However I checked the Oriley's website, they have great pictures, and it showed a smooth shaft. So I would have to assume that is what I have. If it were me I would go down to Autozone (or similar parts outlet) and just have them pull a couple of pumps and check them out that way.
