What´s the best way to separate pistons from rods?

Does anybody knows the method to separate the pistons from rods without hurting them real bad?
Thank you!

do you have access to a press?

I bring them to the local automotive machine shop to have them pressed off. Costs ~$50 for the set of 6.

Right, make sure they have the right die or one close to it, or they'll warp the piston.

what do you mean the right die?

Get a frying pan, heat it up and place the top face of the piston on the frying pan, and allow the piston to heat up. Dont allow it to get too hot. This will make the pistion expand, and allow the gudgeon pin to slide out. I work at an engine building factory, and this is the method we use, apart from having a heated plate instead of a frying pan.

wrong the pin are pressed in to the rods not the pistons heating the piston will do nothing, if any thing recking them. The only way to get them out is to press them out. And to do it with out warping, cracking or messing up the oilring groove is to take it to a shop that dose alot of rebiuld and make sure they have the right dies and take the time to make sure every thing is lined up when press the pins out.

I stand corrected. If the gudgeon pin is pressed into the conrod, then clearly heating the piston will have zero effect. As has already been said, the easist way is to have them pressed out. The titanium conrods we use at work have a bearing surface in the small end, to match with the gudgeon pin, this is then oil feed through the rod from the crank.

What do you build with the Ti connecting rods? Anything cool? well anything with titanium in it is instantly cool.
