N14 Celect tear down.

There’s a shop in the ####ty part of st Louis that can remachine the mating surface of the caps and then line bore/hone the main bearing bore. I had one done a couple years ago for roughly 1000 if I remember correctly. I think they even used new caps. The biggest downside in your case is you have to pull the block and completely strip it
The halfass fix if it’s not to bad is to have a shop polish the crap out of the crank to get it down a thousandth or 2

 

That’s great because the fretting is a pita to fix.
Would you post some pics of the wear on the pump gears…i believe they had a bunch from the celect years that something on the fixtures was off based on the way they wear. It’s really not important one way or the other just a curiosity

 

Fretting was a common issue on the high HP models mainly and was caused in part by the block flexing under heavy load. At one time Cummins came out with a girdle similar to what CAT uses to help strengthen the sidewalls of the block.

 

There was a period where the oil pump shafts were walking forward and the first symptom was loss of P/S usually.

 

I don’t care if you called him Sally on Tuesday’s and Mary on Thursday and he called you fast booty call. You guys have laid down a ton of great info here.
