Re-Linking Chain
I have read other threads, and how-to's but can't seem to wrap my head around this.
I like to consider myself pretty damn mechanics savvy, but relinking chains dont like me.
Every time a try to push the pin back in (with Park tools chain breaker), i go slowly, i keep the chain straight and inline, but every time it seizes on me. And then thats goodbye chain.
Anything would be appreciated.

7/8/9/10/11 chains cannot be repinned. Shimano/campy chains require a special installation pin. If you reuse pins you risk chain failure.
You can start by telling us what chain you're trying to repin and how many speeds.

or you could get a new pin for that brand of chain.

when repinning the single speed chain you press the pin through and of course it's going to squeeze the sideplates together and end up as a tight link. So you move the link up to the loosening shelf and press a little more to re-introduce a gap. You should end up with the same pin protrusion on both sides of the chain as on the other links.

How far are you pushing out the pin when you take the chain apart? If you remove it just enough so that the chain still holds together, but that if you flex the chain, it can come apart, then it'll be easier to put back together, since the pin will hold the chain in position while you push it back in. Does that make sense? This page has some good pictures showing what I'm talking about:

In my limited experience, if you push the pin all the way out, it is a PITA to get it back in.

Of course, I agree that had the OP provided a reasonable amount of information from the start this thread could have been closed in one post. Then again, I'm sure someone would come along and say how it's possible to reuse peened chain pins.
