I have a new std rod bearing cb743hnk set and my clearance are .00225
I know i can mix with one cb743hxnk and that should give me at .00275.
So i dont know if i need to buy full set and change all the lower bearing on all rod for the hxnk or i can only buy 4 hxnk bearing and mix either the lower and the upper, so one rod will have lower hnk with upper hxnk and the other one will have lower hxnk with upper hnk.

What to do in this situation??

buy a complete set and split ,put all the smaller shells in the lower.

Thanks for your help.

For mains I concern myself with the thinner/thicker shells being on the same side. On the rods it makes no difference.

that,s why i said thinner on the lower,if you get in a habit,it comes natural.

On rod bearings it makes no difference other than a .0005 change in how far pistons are in the hole relative to one another. Most decks will be off parrellel to the crank CL more than that. I would by 4 sets of rod bearings and git to gitin. Make sure you measure each journal to its rod.

I have get a full set, I understand your point, but i prefer to make exatley the same on each rod.

Thanks for your help and opinion.

I have measure all the rod with each rod journal, now I am at
.003'' clearance. 7 rod have std size on the upper and thinner size in lower side, 1 rod have std on upper and lower to match the journal.
I think i will be ok with that litle difference like Blue Thunder explain.

I'd be happy with that in conjunction with a HV oil pump and 15-40 oil.
