I'm replacing Rings and want to remove the pistons from the rods without splitting the case.

Are these wrist Pins suppose to be Butt Hole Tight (IMG:style_emoticons/default/confused24.gif)
It's like it will take a Freaking Press to remove them (IMG:style_emoticons/default/headbang.gif) (IMG:style_emoticons/default/headbang.gif)

How about a piston pin puller? We use them everyday to remove snowmobile piston pins.

(IMG:style_emoticons/default/idea.gif) How does it work & where do you get one?

It is a great tool. You extend the inner shaft all the way out and remove the two small nuts on the end of the shaft, they are reverse thread so when you use the tool they do not loosen up. Then you put the inner shaft through the piston pin and put the nuts back on the end. The brass housing is hollow, as you back out the big side of the inner shaft it pulls the piston pin into the brass housing. The brass housing has a nice curve on it to support the piston. There is absolutely no pressure put on the rod at all. It will pull the toughest pins out of most pistons. I added a couple more pics of another pin puller.
