LOL! I thought about that when I posted and knew I was sure to hear from somebody. ;8^)
I hear ya, Gene, and tend to agree. Cranks are worn or turned to under which means the bearings have to be over to fit. Still, the IH listing called them undersize (consistent with the listings I find in their hard copy parts books), just to perpetuate the potential for confusion! On that point, I see it a lot on here and think one of the best pieces of advice to folks who will only ever deal with one or two crankshafts in their life is to take their crank to a machine shop that's used to these things and have them supply the bearings.
The rest of this is offered so that my ramblings don't confuse the guy (I think it was Paul) who initially asked the question, in case he's still following us.
1)On the "over" side of the argument, yep, the two sides of the bearing shells will be a total of .003 thicker (over standard), 0.0015 on each side
2) On the "under" side of the argument, the resulting internal diameter of the shells will be .003 under standard.
Sort of a variation of the half-full/half-empty glass question, I guess.
