Don’t reuse the pin. Just use two Powerlinks. Modern chains have pins that have had the pin mushroomed or “peened” so that they can withstand the bending during shifting better without breaking. When you push the pin out, you break that peened material off and the chain is more prone to breaking because the pin can move. This is less of a problem with the timing chain but it could still be an issue. Powerlinks make for better, stronger connections. It’s just one less thing to worry about.
Here’s what the peened part of the chain looks like after the pin has been pushed out.
