I was finishing up an oil change last night on my 06 WR450. It gave me a chance to try out my new low range torque wrench. Everything was going really well, filter cover on, double check the torque spec, 'tick', all was well. Finished putting on the cover, then I replaced the rear engine drain bolt, set the torque spec, goes on easy enough. Then comes the last bolt which goes into the frame. Set the spec on the wrench, double check it, then go to replace the bolt. Hmmm, it doesn't seem to be getting tighter so I back it off easily with a wrench and try again. Again it's turning really easily so I keep tightening it. Next thing I know the head of the bolt skitters off the floor. Dang. So now I have a headless bolt stuck in my frame. I decided to just clean up and tackle it today with a clear head. I borrowed an 'easyout' from a buddy, thinking I can just drill the threaded bit in the frame, then use the easyout to back it out. An easyout has reverse threads on it so when I turn it into the drilled piece, it should catch it and turn it out. The piece is slightly below the frame too so I can't reach it with a hacksaw to slot it. If I could I could I could use a flat tip screw driver to turn it out. Any other suggestions in case this doesn't turn out like I think it will. Any thoughts on how I can avoid this in the future?
