I have ordered parts directly from cummins. I have them, I think, but my ignorance is obviously showing up too.

What they sent me:

7 sets 14 total (top and bottom) main bearings
2 sets 4 total (top and bottom) some sort of rings? Main
1 set 2 total (top and bottom) rod bearing

Is this right?

You also need to take the time to verify every single part# for every single bearing shell that comes out as the old ones are removed.

Although it is uncommon, (about a 20% chance) that there is can be an alternate size bearing on a crank or mains lobe randomly inside the engine. A single or multiple crank lobes can sometimes have been installed at the factory to compensate for journal clearances, as the engine goes down the assembly line. There is no way of knowing before hand until the old ones that come out are checked individually. This is per individual lobe, etc.. so every single one has to be checked carefully.

Get one wrong and the engine will suffer mysterious low oil pressure issues or some other problem.. and/or can eventually snap the crank.
