Are you reusing the oil pump because it has been replaced recently?

If it's not new, I would follow the old rule of :

"Dont look at a timing chain or oil pump without replacing it."

Just replace it....for peace of mind... if you're already down that far...

Especially for something that only costs $20.

(Well, at least here in the states)

What little oil there is in the oil pump is constantly cycled throughout the engine, so it's no cleaner or dirtier than the oil in the rest of the engine.

If by cleaning you want to check the pickup screen for any debris, sure you can do that. You can even remove the pump cover and see if there's any debris inside the pump. I doubt that you'll find any since the gears will usually chew up anything that gets past the screen OR it gets pumped out into the engine to be later caught by the filter.

You can check the gears for any sign of chips or deep scratches; if you see any, trash the pump.

But there's no "take out the old oil . . ." procedure.
