I'm calling BS on that one:We went to a q&a session with the top BMW tech for the whole Southeast. This was about 2006. He said for BMWs, only use SnapOn torque wrenches and if it is cold out, warm them in the oven until they are 70 degrees. He said some sensitive bolts on BMWs would rattle loose with 1/2 in-lb too little and break off with 1/2 in-lb too much. (Maybe it was N-M??? cannot remember).
I know some will disagree, but that is what he said...and he was way up the BMW ladder. Right after that seminar,
one buddy bought a FJR, one a Verses 1000, and I bought an ST1300
1/2in-lb = .042 ft-lbs - not even snap on is that accurate, and no way a bolt is going to fail in any way if off by that;
If you meant N-m, then .5 N-m = .37 ft-lb and the same applies.
