Opinions on when to change oil pump sought

I posted this on the technical board, but realized that it probably belongs here.

Does anyone have specifications for the various oil pumps? What criteria do people use to decide when to replace the pump in a rebuild?

I look at the surfaces of the moving parts for damage/wear. If the oil pump looks ok then I reuse it. If you have the right oil pressure then you have a good pump. Of course you won't know this until after the rebuild but you can get a hint based on the oil pressure of the engine before you took it apart and the condition of the bearings.

What year motor? If it is an early motor, you should replace it with a later one anyway.
