I might be wrong but I don't think you replace a timing chain. If it was a timing belt then you would replace it. Like I said I could be wrong.

There are videos on youtube about changing the timing chains and cam phasers. How readily can you get parts for these over there? Cam phasers are pretty expensive from what I remember.

Timing chains and guides do wear, so they are a maintenance item.

FYI - your English isn't bad

If the timing chain is making noise, then you change it, it intales replacing the chain guide rails, tensioners & 2 chains. Also you must check the sprockets to make sure none of the teeth are broken. You must check for any metal dropping in the oil pan. Ive done these, its really not an easy job, if you are not a mechanic do not try this on your own.
