Should the oil pump be replaced during the rebuild or is that not much of a concern. I’ve got 146k miles on it and only rebuilding because the transmission is out for a rebuild.
Should I replace NP231 oil pump during rebuild?

Since you already have it out and have 146k miles, I would sure as hell do it if only for preventative maintenance.

He's talking about the NP231, if i'm reading the question correctly, he is rebuilding the NP231 and asking about the oil pump inside the transfer case. I recently rebuilt my NP231, 90K miles, and I did not replace the oil pump. The pump is essentially two plates pretty basic implementation. I took the point of view of for anything not considered consumable (bearings, seals, etc) inspect the current part, if there are no obvious signs of wear, put it back and move on.

Yeah, I got too excited and started tearing the pump down also and only have one torx screw left in it because it’s stuck. If I can unstuck it without stripping it I’ll just put everything in the parts washer and reuse it.
