AndyS Posted March 30, 2015 Share Posted March 30, 2015 How difficult is it to remove the O2 sensor? Are they normally rusted in solid? Or have other folk had more success than me. What technique are you using for getting it off with the exhaust still fitted to the bike? Thanks Andy Link to comment
mneblett Posted March 30, 2015 Share Posted March 30, 2015 Are they normally rusted in solid? Sometimes yes, sometimes no. What technique are you using for getting it off with the exhaust still fitted to the bike? On my RT-P, an O2 sensor socket was useless because it spread too much and slipped on the hex. A 22 mm wrench and a bit of light tapping with a hammer did the trick. If it hadn't have given up pretty easily with the light tapping, I would have stopped and applied some PB Blaster and let it soak in before whacking it again. Link to comment

What technique are you using for getting it off with the exhaust still fitted to the bike? Thanks Andy Andy, I had success with a special O2 sensor socket and a 1/2" drive 24" torque wrench.

Boomer343 Posted March 30, 2015 Share Posted March 30, 2015 If you are not reusing the sensor simply cut the wires and use the appropriate deep socket. If like me you have a few home modified O2 sensor sockets then using a gear clamp or two on the socket after it is in place will help prevent the spreading. Damned specialty sockets can bankrupt a guy. I have also used an air chisel to knock off the top part then fit a wrench over the hex when things were tight. Link to comment
Boffin Posted March 31, 2015 Share Posted March 31, 2015 I used a large ring-spanner. First though, I ran the engine to heat the exhaust as this will slightly expand the hole into which the O2 sensor screws. Andy Link to comment

JamesW Posted March 31, 2015 Share Posted March 31, 2015 And god said let there be vice grips, and there was. Link to comment

AndyS Posted April 1, 2015 Author Share Posted April 1, 2015 Boomer343 and grieffster, to the kind suggestions above, You mention socket. Surely you weren't able to get a deep reach socket to the sensor with it fitted to the bike? I can't see there being enough room. Link to comment
