I have had a few pistons that got loose pins, and it was super annoying. Rattly and fucked but the piston size and shape was still fine. I’d like to have a way to fix these pistons. These aren’t 15k rippers, usually 9-10k rpm.
What if one were to bore the piston wrist pin holes to press in 2 flanged bronze bushings with the flange on the inside of the piston so it couldn’t come out? A small boring bar could cut a groove in the bushing to keep the pin in.
I find this idea kinda neat.. Piston would be slightly heavier but not too much as the bushing would be very smol. One could convert 10mm pin pistons to 12mm pin.
