Thread Problem

Discussion in 'Technical Help' started by Loverobot, Jul 24, 2014.

  1. On my 07 GSXR750 trackbike the previous owner has overtightened the two bolts that hold the side fairing into the frame on either side - I noticed they were working loose

    I havent yet backed them out as noticed when at the track on Tuesday so just snugged them up and taped them

    If the thread is stripped in the frame whats the best way of sorting it - they arent especially load bearing - my friend suggested just medium loctiting them in ?
     
  2. If they are in an alloy frame and blind you can use rivnuts to recreate a captive thread. I am working on a Suzuki RGV 250 track bike at the moment and I have had to do the same to one captive "nut" inside the frame. It's an easy job but requires a rivnut setter, a bike shop could do the job easier and more cheaply if you only need a couple doing. I have the tool so I can set rivnuts over quite a wide range, each one requires a special threaded puller to compress the rivnut.

    Wurth also do rivnuts that are capable of not having to be held in blind holes

    This is what a rivnut from the Wurth catalogue looks like, it collapses on compression and fills the hole leaving a usable thread of the correct size.

  3. can you run a tap down the threads to clean them up? or drill and tap them to next size up?

    can't visulise where these bolts are, but you may be able to use Rivnuts??

    or drill hole in top of bolt and lockwire so it won't turn.

    edit: looks like Red beat me to it, but Rivnuts can be fitted using a bolt and a couple of nuts, no need for special tools.

  9. Thanks - have some rivnuts that I used on the rear subframe (for the same reason) just felt a bit more cautious about the actual frame lol
    Will give them a whirl
    The whole bike will be rivnutted together at this rate lol
     
  10. Unless you are going to go to the expense of welding in a threaded insert it is the only way.
