So I don’t have to replace wheel bolts each time I remove a wheel, and avoid having to replace the entire hubs, I want to try and re-cut the threads in the hubs.
Does anyone know what size tap & die I would need? And as I’ve not rethreaded anything before any useful advice/words of wisedom would be welcome (I shall obviously be consulting several videos on YouTube as well!), and apologises if this is a very novice/silly question!
Cheers
Re-threading is not the answer at all, you need inserts put in the hub to replace the thread, Helicoil or Keenserts (which is my favoured option). It must be done accurately or the wheel will not bolt up tight with the ball on the bolt not aligning to the ball socket in the wheel, so it would have to be done in a vertical milling machine or similar.
What you have is weak, a new hub is probably the cheapest way out.
