hi, i just received my piston ring set but i´ve never changed any ring set, can you tell me how to do this and the tools that i need?

thanks!

Well, you have to take the engine apart, clean everything, and have the cylinders checked for roundness. Then it needs to be either honed, or bored depending upon how round the cylinders are.

To install the rings you will need a good ring expander to get the rings onto the pistons, and a ring compressor to get the pistons and rings into the block.

I recommend downloading the Factory Service Manual from here:

And reading up on the details.

i´ve alredy got the engine apart but i want to know if there is an an exactly position for the rings

http://www.geocities.com/inlinestroker/index.htm Read through this site.....It'll give you a number of useful tips. Punch marks are on top side of the rings. Instructions should be included with your ring set. If you are uncomfortable installing the rings, most machine shops will install a set of rings for $10.00 to $15.00.
