Suntour symmetric shifter

[carpenter]

Hi all,

looking for help - I am not sure what the part is called, but the threads are stopped in the captive nut (has lips/wings similar to brake lever captive nut for tightening band to bars).
Any ideas?

I know the nut you are on about they are the work of the devil for sure
@carpenter are you saying you need some new ones as the thread is damaged in yours ?

Can you put another nut behind the existing de-threaded nut?

Hi Biggs, yes the existing nut is "screwed" so to speak! so I am looking to find a replacement.

Hi Guy, I had thought of that but there is little space - perhaps one thread worth. You have got me thinking though, if I cut a small thin strip of steel with the right size centre hole, then it may be possible to draw it up using a new nut.

I tried a spare Weinmann brake nut this morning, but it is the wrong thread.
I will have to look for a knackered symmetric lever on eBay and see if the nut is usable, as the rest of the lever/assembly is in lovely condition and I like the way the levers are lifted above the downtube.

Use a smaller bolt and blind rivet in the existing nut hole.

Can't re-tap the threads for larger bolt?

It would involve drilling out the body of the lever mount as well, which is possible but getting a little too far away from the "beauty" of the original.
