Greetings . . .
Here's a great article describing why piston pins are offset:
Motorcycles Sacred Cows #17 On a lot of after-market pistons I have seen, there is a little nick machined into the wide side of the piston - which is the opposite side of the crank @TDC when the piston is about to start it's major thrust.
With a pressed in rod is there a really a front or back? The offset is in the wrist pin placement on the piston not the rod . . . no?
On the stove bolts the rods have a wrist pin bolt which is designed to be installed on the wide/cam side so it is opposite of the major thrust.
With pressed in rods does it really matter?
