Have you ever stripped threads on Loop Frame Top Fork "Bolts" or Caps

[Fontain25]

Like the title says , have you ever stripped the threads on a Loop Frame top fork bolt or cap? If you have , please tell us what you did to repair it and maybe how to avoid doing it again. Thanks for any input.

You stripped the fork cap, there is no pinch bolt on the top only the bottom tree. Cap is softer than the tube, get a different cap. Make sure you clean out material from threads in tube and replace cap. If metal goes in the tube you need to remove tube and clean out w/fuel, then add more oil & put back in the upper tree.

Where in IL you from? I had a Guzzi shop in Kingston north of DeKalb. If you need someone to do this, there is Joe (the Guzzi Dr) on north side of Chicago. I been down here 21yrs.

If you were trying to pull fork tube up into top tree you can't use cap to do so, it will strip. you need one of these.




It is a slide hammer I made to pull tubes into the cone shaped top tree

Yes I remember you posted the same picture about 2 years ago , but by then it had happened. Thank you very much for the reply , and I can say I learned something today.

Are you just getting back to it? I have more Guzzi's apart than going down the road. Cost nothing to take apart money to put together.

I replaced the cap , but haven't cleaned out fork leg. did change the oil again.

That would be a costly thread chaser if they make one that big. Stick a rag in tube so you can pull out or vacuum chips. Then use a pic in the threads.

Yes a couple years ago I was struggling with reassembling the fork leg into the triple trees and you suggested this tool. I will make one now . Will have to get a sacrificial top nut and have it turned down. What happened without it was a stripped cap. Need to clean legs more thoroughly anyway.

Wow, thank you Charley, not as bad as I thought. But then I have the slide hammer so never happened to me or customer bike.
You save the day ALL the time!!!!!!!

I buy a lot of weird sized taps and dies on Amazon. If they're just going to be used once or twice, I don't spend the $$ for "the good stuff".

But, yeah - I've never cross threaded a top plug either.

Yeah, I was using the cap to pull up the fork - incorrect! Have to use installation tool or threads will strip. Thanks for educating me.
