Default Single sided swingarm eccentric bolt

It appears I've damaged/stripped the aluminum threads on one of the eccentric pinch bolts. ('95-916) Any ideas on how to remedy this other than replacing the swingarm? It's open on the end and the bolt goes through to the bottom, so I don't think a helicoil would work. Any suggestions are appreciated.

Take the swing arm off have the hole TIG welded, machined and tapped for the same threads. Or just buy a used one off e-bay.

Default 916 swingarm probs

1. Replace with eBay Motors: Ducati 748 916 996 998 Rear Swingarm Axle Hub Sprocket (item 250170776323 end time Oct-06-07 15:22:02 PDT)

2. Weld up and tap again.

3. Drill and out put in insert.

4. Drill and insert captive nut.

5. Remove bolt, put in longer one and nut on the other side. May need a spacer made to make it flat.

Choices. choices.

Default recessed capture nut

Thanks for the suggestions......... a recessed capture nut may be the easiest and simplest. After speaking with a welder friend, he was concerned about the heat issue...........

Seriously, if you don't have one or can't be bothered to check every time, do it with a torque wrench once and mark lines on the bolt heads and down onto the swingarm to show their position when tightened correctly. On subsequent loosenings, just retighten to the lines and you'll never need a torque wrench when you do chain/sprockets etc. Saves a lot of time, especially on a race bike where you're doing it all the time.

I'm always careful about the pinch bolts. They can get so much crud down in the threads through the split in the arm. When adjusting the chain I always take the bolts out and squirt solvent down the holes and blow out all the crud. Then re grease the hell out of threads.

I had this happen on the race bike, like the last post so much crud gets on the threds and eats them up. I just retapped the holes for the next size up bolt and changed to new grade 8 bolts. And USE a tourque wrench!
