Piston buttons question

I'm finally assembling my engine and this is the first motor I have had that uses aluminum piston buttons instead of spiro-locks. I have Arias blower pistons and the oil ring goes into the piston pin area, and the oil ring is what holds the aluminum buttons in place. I also have aluminum rods. With the pistons out of the motor, I can move the buttons around and even push them out of the pin bore some. It appears that when I slide a piston into the bore that it will secure the buttons. Just want to make sure I'm looking at this right. Thanks! Chris

 

yes the bore will hold them in place just fine!!

Thanks guys! I looked at them a few different ways and it seemed pretty obvious that the bore is what held them but wanted to make sure. Appreciate the help and Semper Fi! Chris
