Help!! Broken Pinch Bolt On The Fork Leg! What To Do.

Discussion in 'Technical Help' started by Richie T, Jan 25, 2017.

  1. How well equipped is that workshop? Ideally you need to remove the fork and use a vice & pillar drill to drill it out for an extractor, I'd also drill thru the centre of a sacrificial bolt as a guide for drilling the stud without knackering the hole/threads that are there. A bit long winded maybe but better safe than wrecking your forks. :(

  2. you don't think an easy out would work?
     
  3. Not an "S" so has the Marzocchi forks, probably find a used one easily enough as there was problems with the internal bladder so quite a few changed under warranty and even the retail price for a complete leg was reduced to around £350
     
  4. it happened to my 1299..i made a guide to fit in the lower fork leg for the drill to slide down, bought a 45 deg drill attachment from flebay for a fiver, a nice slow speed put a stud extractor into the pilot hole and out the stud comes..ill have a look for the guide if you want and stick it the post ..the bolts are made of cheese

  9. Bummer, phone decide not to take pictures.. pfff You can still see the thread from the side as there is a cut from where the bolt gos through its seperate the thread part and a hole with no thread were the head of the bolt sits if that makes sense like how the pinch bolt is bolted to the yoke onto the fork for example.
     
  10. blanked off
     
  11. just had it repaired then this happens.. its that hole is tiny and tight.
     
  12. Don't be too hard on him, he said he used a torque wrench...
     
  13. didn't know it was one in the same thing. I thought with a dot punch to start ya pilot bit as close to the Center of the broken bolt as poss and a hand held drill to pilot befor the easy out or stud extractor may work.
    has for me in the past.

  14. It could well do Chiz I've done a few in the past and know how easy it is for things to go wrong when you're trying to drill a bolt with a small diameter drill, if they are made of cheese it'll be a doddle but if it's at all hardened there's a good chance if doing it freestyle the drill can slip off and make a mess of things :mad:
     
  15. im thinking to myself, using a snap on torque wrench- are they suppose to snap bolts yeah snap off clean.. use snap on. pfff
     
  16. 100% but often the part with the snapped bolt is not removable or isnt anymore due to the snapped bolt! so the chance of getting it near a pillar drill is zero.
    But your way if poss is definitely the correct approach. Hey, I'm used to working with timber!
