What is the best method of removing a stubborn bolt?

Got a couple of fairing bolts that have rounded off heads and that are seized in place, Was wandering what the best way of removing them is?

Think 3 of them are allen key heads amd 2 are pozi drive heads. (It's my own daft fault, I never copper slipped them up last time I serviced it!) Have ordered a full set of stainless bolts to replace them, so not too bothered about damaging the bolts, Just dont want to damage the fairings!

 

BIG HAMMER !!!!!

 

The pozi drives, if you tighten them in ever so slightly then undo em they usually come out

The allen key ones, can you tap a slighlty bigger one in? Or tap a torx drive in

 

I'll give them a try, Sprayed a load of plus gas onto them to try and un seize them, Will give it another go on saturday!

 

Strike while the irons hot

 

go easy if theyre fairing fasteners.... try to get them off from behind if you can to avoid damaging the paintwork....

you coud get a dremel of generic rotary hobby tool (!) and cut a slot in the top.

i wouldnt use a hammer or hear on fairing bolts tbh, i'd rather cut them off, remoe the fairing then drill & tap them if they wont come out.
chances are youll be able to get a pair of moleys on the bit sticking out, and a bit more plusgas

 

I can only get to the back of one of the bolts, one is straight onto the frame with the engine directly behind it!

Going to leave it soaking overnight then spray some more on tomorrow night and have a good go at it on saturday!

I take it heating the bolt up is a big no no, Have a small gas soldering iron i could use directly on the bolt.

 

Big hammer solves everything... or failing that.. this handy guide to all things: http://24.media.tumblr.com/tumblr_lrayzyQmzT1qzr4pzo1_500.jpg

 

I would avoid anything that involves a hammer,chances are the force involved will crack the fairing plastic,as mentioned on the allan heads gentle tap a over sized torx bit into the head this will cut into the metal then apply moderate leverage but keep the torx head frimly pushed into the bolt
the others make sure you have the correct screwdriver philips or pozi using the wrong head type will slip out of the bolt head again making sure the head is loxated firmly into the screw head

 

Cut a slot in it and us a flat screwdriver

 

:icecream: Give it to someone else to do.

 

Been tempted to, But funds are a bit tight at the minute!

 

A nice steady hand and a drill will solve your issues pal, mine did it a few days back and thats what I did. I masked up the local area just in case I slipped.

Within a couple of minutes, I had the first one off.

 

that would've been so much more amusing if you'd said you had it off in under a minute! :boff:

was looking for that vid of homer trying to get the wheel clamp off lol - that would do it - just pull up next to a diggerman and ask to borrow his jack hammer :lol:

 

You have already used my first idea, Plud Gas - top stuff. If the heads are rounded off, and you have got a cheap socket set, you could epoxy a socket onto the rounded bolt. Then drink beer and go to bed. The next day carefully add a t bar and it should come off. If it doesn't, try better/more beer next time

 

I have pleanty of old sockets lying around, will give that a go, Think ill pick up an impact driver in the morning and give that a go too!

 

got a snapped stud out of a machine with an arc welder the other day..... it had broke off right inside the thread - i thought it had been bottomed out and broke on the way in as the rest of the thread was clean..
so i got a 4milly rod, turned the amps up and pushed the rof on the end of the stud then earthed it.
it welded the rod to the stud and got it good and hot so it came out easy

another good way is drill a pilot hole then swap for a masonry bit and switch to hammer drill. it will shock it loose.

 

Think my hammer drill would knock the bike into the next street :lol:

 

Where are you located andy? Im a mechanic and rarely get defeated,

Ive got specialist tools for removing rounded screws n stuff

 

I'm in st Helens, usually if I have a bolt that is seized or rounded I just smash it off, or even use mole grips. Only thing with this I don't want to damage the fairings as they are dear to replace and hard to fing in good nick and right colours!
