There is no replacement interval for timing chains. They are much more durable than timing belts and rarely need to be replaced.
A worn timing chain can jump a cam shaft gear tooth, which will throw off the engine timing. If you think that may have happened to your vehicle, then it would be a good idea to replace the chain. If the engine is running smoothly with no noise issues, the best thing you can do is to leave the timing chain alone and not replace it.
