Screw removal problem.

[Sooty09]

Its the screw holding the oil pipe to the frame just above the l/h cylinder.
At first I could not see why the left hand screw is so difficult to get at, the right side is easilly accessible. It finally dawned on me the l/h pot is so much further foreward.
My problem is the previous owner rounded off the torqe profile inside this screw. I have tried drifting it round with a small chissel but it shows no sign of moving. Its a difficult place to access for drilling and applying heat with a flame would require removing the tank etc.
I need the screw out to fit crash bars.
Anybody overcome this problem? Is the screw hardened because the chissel hardly dents it.

Try some freeze spray.

solution idea

Try and either bond a nut onto with chemical metal , or weld it with a mms

just an idea , as i have use such solution a few times.

make sure its total clean with a contact cleaner first...

good luck

I use these at work all the time, they are absolutely magic, just hammer it on the bolt and it will come straight out. The problem with the Torx's bolts is that you only get one failed go, the leverage available is far less than something that grips the outer edge.

"mms"? If that's metal arc welding (MMA) it will certainly shift almost any seized bolt or nut but its also likely to blow the bike's electronics. Even disconnecting the battery isn't always enough.

A really good shout....discovered this about a year ago...brilliant bit of kit used many times in taking apart my knackered DR350.

Thanks Lighty, I have worked in engineering 40 years and never come across these before, I'm mainly office based now so I'm getting behind with innovations. Looks like I will have to buy a set, found some on e-buy at 21.00 for a set of five.

Machine mart do them in a variety of sets at similar prices, there's probably a branch close to most folk....

No doubt these extractors work very well on bolt heads, but the OP is faced with a dome headed machine screw, so what will this wonder extractor grip on?

For this paticular screw you need an extra long screw driver which you can use with different size bits and hammer in to get a purchase.

If you only need the screw out to fit crashbars, then presumably the oil pipe bracket that it's holding will need to move.


So get a dremel or similar and grind the fekker's head off

Quite right...get the screw extracter version on the same site....works just as well.

Find an allen key/hex drive that you can hammer in to the hole, imperial may be the answer, load that up as hard as you dare then get someone else to shock it with the chisel or punch and a big hammer......Give it a few doses of penetrating oil first.
Good luck

The tools work well enough on domed heads, just tap them firmly on with a hammer.

oil pipe bracket does not move, the screw is replaced though with a longer one
