Miche Primato Cranks

Posted on
  • 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)
