Re: Homemade piston pin press

Nice idea. Thanks for sharing. I do this sort of thing for a living. Don't think I'd press against new pistons, especially cast hypereutectic types which are more brittle.

Wait .... heating the rod to install press fit wrist pins is standard procedure. Full floaters are just that. No press fit. They have a bushing in the rod for specific clearance so the pin can move freely. That's why they're floaters. A groove in the piston along with retaining clips keep the wrist pin in place.
