I think the OP is confused about what the pin offset is. Has nothing to do with how far to press the pin in or whether the pin is centered in the rod; pin offset refers to where the hole for the pin is in the piston - in the middle or toward the major or minor thrust side of the cylinder. That is determined by the piston manufacturer. Factory pistons offset the pin location toward the major thrust side of the cylinder to reduce piston slap when cold, at the expense of a slight increase in friction. I haven't really kept up with the latest developments, but I think that some aftermarket race pistons actually offset the pin location the other way. What is Wrist Pin Offset?
So anyway, how you install the pin, or how deeply you install it into the rod, has nothing to do with pin offset. And yeah, just center the pin in the rod.
