Where is the clock spring nut torque located?

Happy to know you understand the importance of properly torquing fasteners.

30 Nm, then an additional quarter turn. That's because if you go by common sense, the nut will never appear to become tight. This is a one-time-use nut that is supposed to be replaced each time it is removed because the threads stretch a predetermined amount when you turn it that extra 90 degrees.

Thank you!
