i can't tell from the picture.

Is this like a tie rod end? Those are pretty standrd items and can be sourced at Mcmaster Carr.

I can't tell from your photo if the stud is swagged on or through bolted to the bracket. These ball attachments are very common to Weber equipped cars and come in all sorts of configurations. Here is a link to one for a Fiat 124.

Well that 's a crappy bit of luck.....and it is swagged; you can see the swagged part of the post that lives on the opposite side of the pivot just above the area Lee circled (I just happen to have mine on the bench atm). If that were mine Lee, for $230 I'd be tempted to drill out what's left of the stud and explore the website Mark posted the link to and see if you can find a bolt-on replacement. Good luck.

Here is another ball stud, a little more expensive but it comes with a nut.

Just dremel the back of the stud so the upset part is gone and it will tap right out, then just use a standard balloted and nut.

 

So not to hijack Lee's thread, but interested in the group's thoughts on an issue related to the carb linkage pivot. As mentioned above (and in other posts), I'm in the middle of the same project as Lee. Mine started out as identifying the cause of excessive stiction in the return action of my throttle linkage, which was traced to (mostly) being caused by 45 year-old molasses masquerading as grease in the needle bearing you can see in the pic Lee posted of the pivot. As a young bike mechanic working on high-end bikes, we used to lube select bearing surfaces with oil instead of grease to reduce friction by 0.000005%.
Given that the carb linkage pivot is well-protected from the elements, a pain in the ass to get to, and does not have a high load on its bearing, I thought it would be a good candidate for this treatment; not to improve performance but to improve serviceability. Thoughts?

Thanks Lee.....the only ransom I'd be interested in is more info about our cars.
Personally, I'm not worried about any oil drying up because I would lube the pivot on a regular basis if that's the route I end up taking. The needle bearing isn't sealed, so you should be able to get the lube to wick into the bearing. Failing that, you could remove the C-clip that retains the pivot - without dismantling the linkage - to gain better access to the bearing.
If you wanted to be really fancy, you could drill a small diameter hole in the part of the pivot that holds the bearing and create a lube port.
But that's another project for another day.....

I use a very light assembly lube when freeing up old linkages. I agree the grease is not needed. Just something to keep it from rusting away over the years.


P.S. I have a linkage ball pivot. It fell out of a TR linkage in 1995 and the arm was just replaced. I saved it just in case I needed it later.

 

From the company that brought you kroil..

I like their silicone oil and dry film spray. Good line of products across the board as well.

 

I totally misunderstood what you were looking for but Mcmaster_carr has a large selection of ball studs as well:

Yup; Super Lube products and Tri-Flow are what we used in our bike shop back in the day. The Super Lube especially leaves a particularly tenacious film.

Congrats Lee!
Yup, it took a couple of dunkings in the ultrasonic to get all the nasty out of mine.
One thing I was concerned about in using a bolt-on replacement ball joint was the stud and nut interfering with the linkage on the back side. Let us know if you run into any issues there.
