From reading other people's posts they say to check the size of the bearing you pull out to be sure you are putting the right size back in.

yes, you have to verify the part#'s as they come out (+ measure them) to ensure cummins did not switch sizes on it mid-engine or some other thing during manufacture.

Only about $1700 for those parts? Why would anyone skip out on a preventative measure like that where the relative cost is so low? Hell, I think my OEM CAC costs more than all those parts!

Update: I only got the first two mains done today. I was waiting on my wife to get back with parts, then it just takes awhile doing it all by yourself. A lot of ins and outs back and forth under the truck.
So I am glad I decided to go ahead and do them. There was no visible soot in the motor until I dropped the first main cap. Needless to say it was not as clean as Rawzes! It took about 45min to carefully clean each cap. The lower bearing surfaces on both were showing wear. The crank journals still look beautiful, so I guess it was the right time!

Also refinishing the oil pan while it’s off with POR 15, and then Massey Ferguson Red, (it’s $4 a can instead of $11 for Cummins and it matches almost perfectly!

yeah, looking that at upper rod cap bearing, it was definitely getting due.
