Half-Link Question:

    I had to install a half-link when I put on my new Worksman rear wheel because the sprocket was 22T instead of the stock 20T, and the chain had to be lengthened to keep tension on the drive sheave.

    That half-link (offset link) recently failed, so I bought a replacement (#43), but before I put it in the chain, should I hammer the pin to flatten it out as I did my first half-link, or use a small cotter key in the hole on the end of the pin?

    The hole is the size of a #56 drill bit (.046"), but I don't have any cotter keys that small.

    Hal, that sounds unusual, as every half-link I've bought has always come with the cotter pin. I've always used the pin and have experienced no failures (as yet).

    Hey Kilroy:

    Thanks for letting me know that I already HAD the cotter pin!

    It was in the link's plastic bag in my workshop trash can!

    I think the first half-link failed because I didn't know that a cotter pin came with it, and I assembled it by hammering on the pin, which didn't upset it enough to stay retained in the link.
