Just installing a new Miche Primato Crank and it says "lock 35Nm" on the little plastic bit around the nut. Thats a hell of a lot, no?
Whats the plastic ring for? Is it just a washer.
The reason I ask is that it is not flush with nut, which made me think it is supposed to ping out and be flush or "lock" when you reach 35Nm.
The plastic bit is just a washer. Its there to keep the crud out of your crank threads. Its definitely not going to ping/lock etc when you reach 35Nm. Thats what a torque wrench is for.
35Nm is not a huge amount for crank bots esp press-fit. Most cranks bolts are spec'ed around 305-391inch pounds (310 inch pounds is approx 35.0Nm)
