Swingarm bobbin bolt stuck in swingarm
Hellooooooo fellow riders from across the sea Got a problem I hope someone can offer sound advice on...
As per pic below, the bobbin broke off but the bolt is still stuck in. As you can see...there is a tiny bit of it raised...just a little...but no enough to grip with something. Any idea how to get it out? I thought about using that super bonding cement...glue a bar onto it...leave it for 48hours and then unscrew it. If that super bonding cement can hold a connection with tons of pressure...surely that will work? Otherwise..any recommendations on how to get it out? PS: Yeah the chain doesn't look great...I need to replace it |

I think the hole is M8 and goes all the way through ( I'm at work so can't look ). Bladder it with eas-it oil and leave overnight. Give the center a sharp tap with a hammer and drift, then drill it 6 mm from the other side. Hopefully the heat and rotation should just wind it out.

Re: Swingarm bobbin bolt stuck in swingarm
The SV went in for a new chain and sprockets (as you can probably tell from the pic above it was needed)...and I asked them to try get that piece out. They couldnt get it out...seems the thread is a bit messed when the bobbin snapped off. A little worrying as this happened with the previous owner and I dont know under what circumstances it broke off. Bike shows no other sign it was dropped or in an accident...so how it snapped off...no idea.
Mechanic said there are people that can come to my place and remove it. Even so, risk of the thread on the swingarm being stuffed is high. So I have 2 choices...get a paddock stand that connects to the other side of the swingarm, or take the bike in for a new swingarm (the one side is scratched badly too). I have a feeling a paddock stand for the one side only will be cheaper than buying a new swingarm and getting it fitted.... |

I know you're over the pond, but an ABBA stand is a worthwhile investment, would save you a lot of hassle. http://www.abbastands.co.uk/

Re: Swingarm bobbin bolt stuck in swingarm
There are such things as left hand drill bits, designed to cut while turning counter clockwise. They're a good choice for drilling broken bolts like yours prior to using a screw extractor.
Many companies make screw extractors, some work better than others. I prefer those made by Snap-On. |
