    Wheel Stud Broken

    Checking the bike over before taking a long trip and noticed a lug nut missing.  Come to find out the wheel stud is broken.  I assume I can drill it out.  Anyone have specs on the wheel studs? Hopefully i can get one locally or from amazon.

    The bolt UN-threaded and it appears the lug nut side is a m10x1.25 and the hub side is a m10x1.5

    Found a dorman exhaust flange stud locally at oreilys. I  bought a m10/1.50 and re threaded the lug nut to fit M10/1.50.  I'd like to know what grade/class this bolt is.  This is probably going to be a temporary fix until I find a higher grade/class bolt.

    Wow! Was that screw too tight?
    Therefore it is advisable to give the tightening torque recommended by the manufacturer and always tighten sequentially.
    Only motorcyclists know why dogs stick their head out the car window.

    There is another Member ( Garmin Dave ) that had sheared off Wheel Studs.

    Topic here : Rear Wheel Studs Sheared!

    "Triumph" wanted around £1300 to replace the complete Final drive assembly !

    His local Dealer in Newcastle managed to replace the broken studs,
    actually they replaced all of them with higher tensile studs, at a much lower price !

    There are no details in that Topic of the size / type of stud used,
    but perhaps you could enquire of Garmin Dave to see if he has any contact details ?

    Meanwhile I would strongly advise against using an original wheel nut ( M10 x 1.25 ? )
    that has been re-tapped to screw onto an M10 x 1.5 thread !

    Well Coconut you beat me to it.  I was about to dive in but you have it covered.

    I do not have exact stud details for the replacement except all five were replaced for exactly the same thread but higher tensile strength than originals. 

    I firmly believe this is a case of using a material that is just right for the job at the right price whereas in the past an engineer would pick the best item for the job and not pander to the bean counters wanting to save money with tighter specification parts.

    BMW, to be fair most manufacturers, have gone down this cost-saving route and lost the mantle of being bulletproof and over-engineered.

    If you use your bike a lot and all and sundry people have worked on your wheels I'd include counting rear-wheel fixings as all present in your POWDERY checks.  Triumph says the studs are fine if tightened to correct torque with a recently calibrated torque wrench which is double-speak for there is no margin for overtightened wheel nuts.
    Love, light, and kindness,

    Dave

    As an engineer I would be VERY wary of using an exhaust stud to replace a wheel stud. Okay for a "get you home", not for anything else. As Coconut said, tapping an M10 nut to a different pitch is also a no no. This will leave very few, if any useable threads in the nut. I would be replacing the stud and nut ASAP with original parts. Mind, you did well to get the broken one out. I hate getting broken studs out.
