    Rear derailluer help - no tension

    I'm pretty new to bike mechanics, I can't figure out why my rear der. doesn't have any tension. All I did was removed the pully gears to clean them and when I reassembled it this is what happened.





    Please help.

    Can you move the arm easily? You might of overtightened the bolt holding it on, if that would even make it do that.

    You could try taking it apart again, and lube the parts. It does look a bit dirty.

    older ders can get "unwound" loosing spring tension or sometimes the spring gives out. try to see if you can wind the tension back in..if it feels like you're forcing it you probably are so stop. good luck

    There should be a coil spring inside the cap part that is highlighted in the photo below. Generally it's wound up and the end goes through a hole that keeps it taught. You can wind it back the way it should be using a pair of needle nose pliers. WEAR EYE PROTECTION if it's in there loose.
