If the components are stock the pin will need to be pressed out. for my small block chevy, I took a socket about the size of the pin in diameter and used a hydrualic press to get the pin out. Make sure the socket is smaller or else it will get cuaght up. This is the at home way of doing it. If your going to put em back together or reuse the stuffI would have a shop do it, I think they have specail equipment to do it and its precise. If their floating you just remove the locks holding the pin in and slide the pin out.

It takes a pretty hefty hydraulic press to do it. Yes you can get them off at home, but good luck trying to get them back together. The piston pin boss must be properly supported to press the pin back in.

Yep there is a machine shop locally that does it that way. There is just something I do not like about seeing the wrist pin end of a rod glowing red hot.

pistons

You do not really say what you want to save... The Piston, rod or both.. If you are going to install new pistons they need to be installed by a skilled shop. It's not something the average at home guy can do. So you might just as well take the piston/rod assembly to a local shop and have them do the entire switch, besides if you are doing a good rebuild you will want to re-size the big end of the rod. So removing the pistons is not really going to save any money. I have a package deal in my shop when i do the entire job and i would not really knock any thing off the price if the rods came in empty...

Vince, I have it to the point with my rod heater that i can just get a straw color ( about 350 with a temp stick) on the rod and not "STICK" any pins installing them. I have seen other shops make rods blue, and red...I have never seen any issues with this even thought all the tech books tell you not to do it...
