My Pete rebuild

Most already come this way from cummins when they are new if I remember right. matter of fact, the wrist pin bushing clearance it actually the absolute most precision, and critical measurement in the whole engine. The longevity of the engine depends on this very heavily, right along with raising of the liner heights above factory settings on an engine that has a lot of miles and is being rebuilt.

Like I mentioned earlier, 2 reman rod bushings were sloppy and out of round. One vertical measurement was @ 2.5032"

Not sure why the fractured rods have even tighter specs on the bushing but still use the same piston pins?

I didn't write them down as I checked the rods, but the 6 saw cut rods I'm using measure 2.5023-2.5026". All of which are looser than the 2.5017-2.5023" for fractured rods.



I checked some cores before I sent them in and they were mostly all worn in the vertical areas.
