Clutch Install gone bad
Attempted to replace a slipping clutch.
Got to the last screw/spring when I heard a pop - spring flew out and I saw the bolt broken off. Any suggestions on how I can get this out ?

Drill the screw with appropiate size drill & use an easy-out. Be sure to center punch the center of screw before drilling & use WD-40 or PB penetrant on threads to ease removal. Easy-outs can be bought at hardware & auto parts stores usually with the right size drill included or in sets marked for which size drill to use. Some like to use reverse drills(left hand) to ensure better grip of easy-out. Lay a rag underneath to catch chips from falling in case.

Yes pull the inner hub and run it down to any machine shop and pay them 20 bucks to remove it ... Trust me on this one , if you have never drilled and removed a broken bolt you will screw it up and be buying a new inner hub ... 20 bucks and no problem ...

if you do do it yourself, and this tip is good for others and other uses.... use a reverse direction drill bit.
Often they will catch and turn the broken bolt out.
If not at least it is going opposite direction of the threads, and they seem to drill straighter, maybe due to the direction th bolt was torqued when it broke...
I dunno know why but my luck has been 5 times better since I went to reverse drill bits!
anyway reverse drill bits and easy outs are the shit!

I second the left hand bits. It will spin it out of there. Did it for a friend's Busa last week.

Don't sweat it too much.. if you booger it drilling, the center hub it is only around $70 from cheapcycleparts.com or wherever you get OEM parts. Will the pressure plate come off over the busted bolt? You will likely find the threads are boogered anyway if the bolt broke off.. The torque on those spring bolts is only 8 NM (6 ft lbs) so if it broke.. something is wrong up in there. Gonna be buyin' new spring bolt anyway.... might as well get yourself a new hub too if the threads are hammered.
