My 10 speed XT rear mech has lost tension after 600 miles. It just dangles vertically from the hanger and doesn't spring backwards to keep the chain tight.
Is there anything that I can do to the mech or does it need to be binned?

TIA

    there is a screw on the mech that puts pressure on a small tab on the frame

    turn it untill the mech tighten up, not too much now

    It has spring tension if you push the cage forward but only springs back to the vertical position and no further back.

    Fixed it! The stop screw on the cage had come out and when I taken the chain off the thing span round 360. Only noticed this after I had the spring out completely. Cage spun back round and new stop screw fitted and it is all good!
