Ultegra 6800 rear derailleur

[Shwetty]

The metal of the spacer through which the b-tension screw is threaded has failed (see attached images), which meant I couldn't tune my gears properly. 

I cannot find a replacement part anywhere, and the next available solution is to replace the entire b-axle assembly. 

 

Does anyone have an old 'broken' 6800 or 6870 rear derailleur lying around that could potentially be stripped for parts? Would be hugely appreciated! 

Cheers

I have a 6700 but I doubt that it is the same. I will dig it out and see.  You could also thread a nut onto the screw between the stop on the hanger and the "spacer".  This will give you something to tighten against.  Another possibility is to tap out the part to take a bigger screw.

Looks the same.  It's yours for the postage.

Much appreciated David! 

I managed to source a b-axle assembly from CWC, so I should be able to sort it out once it arrives. 

Thanks again for your help.
