Thanks Dan. Now I know what fastener was in question. It looks like a candidate for blue thread locker to me.

Just to reiterate, 149 ft lbs is the wrong number for sure. Forget it was ever mentioned. I don't think there is a single fastener on a BMW motorcycle that takes that high a torque.
Sorry, I must have missed something along the way.
I agree with you, the rear lugs take about half of that.

If I'm remembering correctly the large nut on a Ducati rear wheel is around 170 ft lbs.

Final drive pinion nuts get 200 Nm and airhead output flange nuts get 220. They’re the only ones I can think of that go that high and you need to set up properly and work a bit to actually achieve them.
I wonder what the shop was looking at when they quoted that on the shifter.

I have worked with some guys that could turn wrenches for the rest of their lives and still could not do an oil change without screwing something up!

Sure, but I have met a couple of dozen at tech days that sought to learn. Lets not get too supremist here.
Absolutely!!
I'm a "Hobbies Wrench", started out without a clue several decades ago. I;m sure I asked my share of dumb questions and still do. The fact that people are still interested in working on thier bikes and learning how they work impreses me. Keep the hobby going....
Perhaps. However, in this thread's case, it is information provided by the (suppose to be knowing) source (BMW dealership service department), that shouldn't be allow to disseminate.
I don’t know about all that. I myself try to check information in two directions and realize that if I call a place for information, it’s probably going to be a bit rough. If it’s an established relationship, the information flow will be a lot better and free flowing.
I realize that calling for a torque spec means bothering two or three people for the information. Sometimes questions receive a better answer with a visit. Even calling a distributor for information may not get what you need unless you can get to someone that has actually done the work.
Think how much better things would be if everyone respected each other’s time.

Oh, I respectfully disagree. When the "visit" is a 160 mile trip, then a phone call is more than proper. Especially if one just dropped $15-25,000 on a unit, from their dealership, that the customer now needs just one CORRECT torque value. I'll assume 1% of the unit purchase should cover the cost of a two digit response. Of course, they give me a thee digit response that was 130 lb/ft too much. However, I still respect their time by not calling them as much. Plus, they, as well as most other dealers, tell you during the selling phase that their service department is the best around and don't ever hesitate to call us with any questions...that's what we are here for.

Which is among what he said. You do have an established relationship with that dealership.
