Stripped threads

I've stripped the threads on two holes in my front wheel and its the holes where the brake discs secure to. Would it be ok to repair with helicoils.

Regards dp

Hi Dave

Looking at your profile i presume you are talking about your Hayabusa,you can do a helicoil repair as a temporary repair to get you back on the road for now.The reason you have stripped the thread is the reason you can only do a temporary repair(in my book anyway).The disc bolts are not only held in place by the torque setting they are tightened too but also thread lock.A little tip,when undoing steel bolts into aluminium with thread lock its always best to apply heat to soften up the thread lock while undoing them otherwise you will strip the thread.This is also the reason why the helicoil can only be a temporary repair,coz if you do the job properly and add thread lock to the repair helicoil,then the next time you remove the bolt theres a good chance the helicoil will come with it.A good engineering shop should be able to fill the old holes with Ali weld and re-drill and tap them again,or purchase a new second hand wheel from a breakers.

Good Luck

KCMC:tongue:

i would

take the wheel to an engineering workshop and have them sort. once you start pissing about with helicoils etc on an important part of your bike, you can spend more cocking it up. they could sort it properly

Is right as you can thread lock the time-sert in,but i would say again you would need a good bike shop or engineering shop to fit a time-sert,not make a mess of it yourself as stingy1 says:tongue:
