timp Posted February 11, 2006 Report Share Posted February 11, 2006 Use a left handed drill bit Quote Link to comment Share on other sites More sharing options...
charliechitlins Posted February 11, 2006 Report Share Posted February 11, 2006 Use a left handed drill bit <{POST_SNAPBACK}> Yup. Or cut a straight slot with a Dremel and cutoff wheel. My hand impact driver has a fat bit, so I stack 2 cutoff wheels to make a wide slot. Quote Link to comment Share on other sites More sharing options...
flatslide Posted February 12, 2006 Report Share Posted February 12, 2006 dont worry about it unless the dirt is nearly to the top of the filter. Or sell it and buy a new bike, dont say anything to the prospective buyer. Quote Link to comment Share on other sites More sharing options...
ruffrider Posted February 12, 2006 Report Share Posted February 12, 2006 In the Screwfix catalogue there is a "Bolt Grip Set". They look similar to sockets but are designed for exactly this problem. They appear to have spiral teeth on the inner edge. Not sure how good they are. The catalogue I'm looking at is issue 77 and these appear on page 466. Part No 96028-77 cost Quote Link to comment Share on other sites More sharing options...

wobbly1 Posted February 12, 2006 Report Share Posted February 12, 2006 Try the cheap solutions first. 1. Grind the head off a small drill bit so that the end is flat. Use a reversible electric drill switched to slow speed reverse and lots of pressure. Sometimes this works and sometimes it doesn't. 2. Drill the head off the bolt using a large drill bit. Be careful not to drill too far and damage the plastics taking it a little at a time. Once the head is removed youshould be able to remove the filter cover. There should be enough of the bolt sticking out to attach some mole grips. If the bolt is rusted use some penetrating oil before trying the mole grips. Good luck.

g4321 Posted February 12, 2006 Report Share Posted February 12, 2006 If the screw head cannot be reached by using a normal drill bit because of clearance issues with the drill itself then one option is to borrow a dremel or similar with a right angle adapter. This will allow you to access the offending screw. Whether you use a cutting disk, drill or grind stone is up to you. Once you have the head off the screw use a mole grips to unscrew the remainder. Good luck! Quote Link to comment Share on other sites More sharing options...
james111089 Posted February 12, 2006 Report Share Posted February 12, 2006 use the small dremel with the cutting disc to form a slot for a screwdriver. Quote Link to comment Share on other sites More sharing options...
alan bechard Posted February 14, 2006 Report Share Posted February 14, 2006 Two drops of mig welding right on the top, grab with Vice grips (I think you guys say Mole Grips) and pull it out. Course you got to have the mig welder, and put your ground somewhere so that it contacts, sometimes on a screw driver touching the side of the head of the screw. That is after you have goobered it up trying the other ways. One of my favorite stories. Main Rotor blade tip cap, two cobalt bits and a screw extractor broke off in one #10 cs screw.... yep, all stuck in one. I get the job and get a lecture about how I better not screw it up as this blade is worth 60K or so......... I replied that it was too late, all I would do is bring it back from already being screwed up. And yes, we got it. Quote Link to comment Share on other sites More sharing options...
