Subject: [FlyRotary] Help - O2
sensor removal
After about 130 hrs my O2 sensor seemed to be getting a
little sluggish; so I decided to replace it. I put a wrench on it and unable to
budge it. A bigger wrench and still no luck – getting worried about
cracking the weld around the bung, or some other damage. Any ideas about
getting that thing loose?
I didn’t put anything on the threads when I put it
in – perhaps next time; but what?
