I have a bigger problem

... the ring nut is broken:

Is it easily replaceable?

ask your dealer, otherwise I can check, maybe I still have one on my replacement fork (don`t remember)

You can make a new one!

did you do it by yourself????

I thought about working it with a lathe, but I am not sure about tolerances... I don't know if they should be stricter than I can do.

Nope,
I got the picture from a guy in NL or UK, who has made it. I changed my front fork instead.

I have just that ring nut(part number 6.) for sale. New one, original Ducati spare part in original package. But have to say, that, that part is not so cheap....

ehm.... what does it mean "not so cheap" ?

Now I know do you mean with "not so cheap"!

I went to a Ducati service and it checked in Ducati, but it is not available. He suggested me:
1) to change the Paso
2) to check for used parts
3) to build it by myself

So... does anyone has a used ring nut at a reasonable price?

There should be no great problems in building a ring nut for a good machinery factory...
I made a lot of small parts when I worked in such a place...

Iceriani, Nicola can make to You such part... Dont worry...

If you need a full engineering drawing, let me know. I can have one of my slaving engineer draft it up for you.

Wow, it would be great! Actually I am waiting for some dealers which I asked for used parts, if they won'f find anything I surely will build this component. In that case, a good drawing would be great.

I just find that ansim's drawing is different from original piece: ansim's drawinf shows a exagonal nut on the top, while original piece has a round nut with thread inside.
Why this difference? In case, which component should I build?

The hex is just there for turning. It does not need to be a hex for any specific reason. It also does not have a slot for the "pinch" bolt. I will have it drawn up in Autocad so you can have it made if need be.

It might be possible to put in a small (M3) hex-bolt in the top of the new ring nut as a stopper. In the hex part.

It is available small hexbolts just for this purpose, without the normal "head", the hex is set internal on the bolt.

Please be patient with my poor english

but I would like to check if I understood well.

I understand that the drawing represents differente views of the same component.

Is this a unique component or is it made by two different parts, the circular one plus an hexagonal bolt over it?

The original component has a "pinch bolt", so we don't need to turn tightly the entire part, we just have to tight this bolt.

The modified component doesn't have this pinch bolt, but has an hexagonal nut, so we need to turn the entire part. If we want to be sure that it will not loose, we can add an extra (I guess very thin) hexagonal bolt on the top of the whole component, as a locknut.

Both solutions should work with no problem.

Is this correct?
Maybe with the cad drawings it will be even clearer...
