That 4th ring being oil control. Beyond that, is the 3 ring piston a different set up on oil control rings or the same? Piston ring width/top gap/end gap from 3 to 4 piston? Me? If I desired a 3 ring set up, would go with the 3 ring piston.
If it all checks out, then going with a lack of a 4th ring should not hurt anything.
I suspect it will be different because Ford would not add anything that was not needed.
Cost difference from 3 to 4 is how much? Times 1,000,000,000 tractors is how much?
So from a manufacturing standpoint, why add something to a machine that is not needed?
