Gary,
When I changed my pump I spun the shaft, there was little resistance. It felt as though I was hitting some sort of lobes, much like you described.
The original did it, and the new HRVP felt identical.
By the way, just over 10,000 miles on my industrial injection Hot Rod pump so far. I don't think there's any reason that it shouldn't last as long or longer than the original.
