I have knackered the threads in the hub for the lockring for centrelock disk. Does anyone know of a repair, somethin like a helicoil, i dont think running through with a tap will sort it out or even if a tap exists
Anyone any suggestions?
Cheers

Doubtful if there's anywhere near enough metal to helicoil it, if it's really knackered then you'll probably be looking at rebuilding with a new hub. Be wary of un-named used OE front hubs if you decide to go that way, some have been subject to a recall due to the entire mount shearing off the hub-shell (and no, it's not just a precaution, we have one sitting in the workshop right now).
Bit of a sweeping generalisation, there are approximately 8,493 different unbranded OEM hubs, I don't think they've all been recalled.
I agree that I don't fancy your chances of a repair though.
how did you knacker the thread? EDIT - bit of a silly question really, but its such a fine thread i can't imagine you would cross thread it, so assume over tightening,
I have some new centrelock disc hubs and it would just be my luck to make the same mistake, so forewarned is forearmed 🙂
pick a rotor size, glue it on with threadlock.
I'll go with hamfisted at 5/4 odds.
It was a very sweeping generalisation, but not that many OE hubs are centrelock, so narrows it down a touch. For the cost of a brand new (or used) known brand, i'd probably prefer to know about these things,and not take the risk.
Hi Rab
which hub is it, is to worth anything?
If its a basic shimano one then it may be worth looking at changing it.
If its a XT or XTR might be worth trying to repair it.
You might struggle to find a die big enough to do a centre lock thread, so you would be looking at filing the threads. Tricky but you've got nothing to loose.
I'm in Shropshire, Minsterley (i think we have spoken before) i can have a look, i can certainly do a wheel rebuild if thats the way you want to go, or look at bonding a rotor on.
email me a close up of the thread, email on profile.
