I believe I found the info....torque to 28 Nm/335 in.lbs./28 ft.lbs. after applying loctite 221/222.
If anyone finds different, please post.
Unless there has been a change in the value that I am not aware of, I believe the correct foot pounds value specified by Rotax is 30 Foot Pounds
Ever since incorrectly specified torque value error was discovered (7 years ago) and the change made to using the correct 30 FP value, I am not aware of any RV-12 having the bolts get loose.
I torqued mine originally to the old spec and got a little turn on them at the first annual. I went to the revised 30 Ft-lbs that annual and they haven't loosened a bit in 5 years.
