Pressed or floating pin

The rods I have now have pressed pin installed, i'm guessing they are pressed pin because they are tight on the rod, but slide in the piston. My question is if I have pressed pin rods can I use floating pin pistons on them or do I need a different pin.

I think you need to have bronze bushings machined into the rods to use floating pins.

You can have floating type pistons and pressed rods, IF AND ONLY IF you leave out the pin retainers in the pistons. Other than that, they're the same. The pins are the same. The only difference is how they're retained in the piston; and like so many other things, you must have one, and only one, retention method in effect at any one time.

Be glad I didn't just say "iff"

Seriously though, so much of this is nothing but math, physics and logic... as long as you stick with those things, you can't go too far wrong.

I was a math and physics major back in my younger and even more foolish days. Hard to believe I was ever more foolish than I am now. Oh well, if I only knew now half of what I thought I knew then, I would be almost not the idiot I am.
