Like he said.
In a stock type press in rod bolt, the bolt is the clamping force along with the locating pin.
If the pin is changed, the location of the cap may change as well.
In an aftermarket rod, using screw in bolts, there is a locating dowel that mates the two halves together. In these cases, the bolts are simply providing clamping force, and not locating.
I would always resize the rods when changing bolts. But, I guess the question would be... How often are you changing bolts that you're concerned about resizing the rods?
hey have you seen the grp aluminum rods with the grooves for alignment ?
what happens when the rods get hot,and the cap,and arm come closer because of heat ,and torq?, this will be tighter on the crank, has anyone had any problems like that?
will these rods last for years??
