916 Rear Shock Bolt

Discussion in 'Technical Help' started by roadkill, Sep 12, 2020.

  1. Struggling to remove the lower rear shock bolt that goes through the shock and swingarm.. I have used quite a bit of force with the hammer and bar and it's not moved a mill...

    Any tips or tricks on how to proceed?

  2. From memory don’t you just keep undoing it via the chain side with Allen socket rather than take the “special” nut off and knock it through?
    I took mine off last month and it just unwinds. Edit. And suppler the swing arm with a stand/bricks/wood to remove tension from the thread.

  3. I have tried constantly turning it but to no avail, the special nut at the end just worked itself free and dropped off
     
  4. Are you supporting the swing arm per my edit?
     
  5. Yes with a tool box, will try and add some extra packers and see if that helps..

    Cheers Jamie
     
  6. Try reattaching the shock at the top mount first as this will take some pressure off too?

  7. 5 hours later and still no further , going to leave the shock in place for now and continue to remove the engine..
     
  8. You haven't said, but can you turn bolt or is that seized in the swing-arm eye?
     
  9. Turns freely both ways.. Going to soak in penetrating solution for the next few days..
     
  10. Thanks, next, when you are rotating the bolt, look at both the rose joints, one in the damper eye and one in the linkage rod eye and see if the centre part that the bolt locates in, are both revolving with the bolt or just one. This wil help to tell you whether just one or both, are seized onto the bolt shaft for starters. As you say, lots of soakage might help. Might p.m. tomorrow with some more brutal suggestions that have worked in the past.

  11. Buy a blow torch and heat up the swing arm.

  12. A bit of a nuclear option, no, Cookie? I’m pretty sure this is a time and patience situation with lots of penetrating fluid, a bit like swing arm pivot bolts.

    Now if it were the front sprocket - well that would be a different matter :mad: :joy::joy:

  13. After soaking it, try getting a mate to slightly tap the bolt from the other side while you’re turning the bolt head.

  14. Soak overnight with plus gas, wash off next day and apply a little heat if possible Then turn it out,
    The heat allows the surrounding metal to expand, hopefully loosening the fit.
     
  15. Is it left hand? Just a thought.

  16. In other news

    I haven't touched the pivot bolt today and my plan was to have a go at the swingarm bolt, I was dreading this as if the shock bolt was anything to go by then I'm already in serious trouble..

    But would you believe it, straight out and not one issue with it! Still shocked now.
