Couldn't have said it better myself! The torque setting given seems to be stupidly low. But it's all to do with the grip on a taper (see previous page and physics lesson!). DO NOT EXCEED THE TORQUE FIGURE GIVEN

Interesting thread, I've been guilty of wrecking some QH couplings in the past by overtightening, I now have a torque wrench for bike repairs that will go this low.

The service memo shows this has always been an issue!

providing of course the threads are the right length, I know the ones on mine stick out a fair bit more than 1.6mm beyond the nut when still rattle loose but then they are not original

It's NOT the thread length that matters. It's the torque that you tighten the nuts up to.
