    Default Repairing stripped extral threads

    Wanted to see what methods if any I can try on this part to repair the external threads. The threads on a 1" steering stem from a Harley front end are stripped in the middle. The stem is welded in and removing it would mean re-chroming which I am really trying to avoid.

    The portion of the threads that are stripped is where a thin nut that preloads the tapered neck bearings go, then a top clamp goes on over that and another nut at the top.

    Do people ever lay down small beads with a welder and run a die over them?

    Not sure I’d invest a lot of effort repairing that. It is one of the most critical components on a motorcycle. I would just replace it.
    On a display bike, historical value, a weld up and re thread would probably work but the HAZ and weld hardness would cause me issues...

    Make a thin walled 'spacer' about 3/8" long to put between the nut and top clamp which moves the nut to good threads. If need, chrome the spacer.

    Make a new nut that includes the sleeve or that is just taller.

    Make a bit undersized to insure less slop.

    Also get a thread file to clean up what is left.

    Longer area of engagement needed here.
