The thread where the derailleur barrel adjuster screws into the derailleur is shot! I cannot get the barrel to screw into it.

Is it possible to re-thread or the derailleur is finished?

Thanks for your help!

A couple options:

find the size of the bolt that the adjuster would be and get an appropriate tap to recut the threads. You may get it to work if there is enough for the adjuster to grab (not a high strength application)

or

Try one of the thread repair compounds available at an auto parts store.

or

drill it out, tap it and install a heli-coil of the correct size.

or

drill it out, slip the adjuster into the hole and use the adjuster on the shifter to handle cable tension duties.
