2.) Make sure that the bolt will thread into the crank snout deeper, then if it had the washer on it for proper clamping. Bolt does not bottom-out, leaving the hub unclamped.
3.) Coat all threads, clamping and thrust surfaces with Loc-tite #51605, Heavy duty anti-seize, or Loc-tite #51048, Moly paste. Do not use a thread locking liquid on the threads.
4.) Assemble and torque the grade 9 crank bolt to 400 foot/pounds.
5.) If you are using a torque multiplier, add an additional 10% of the torque value, for mechanical loss in the torque multiplier gear drive. (400 x 1.10 = 440)
6.) If you use a drive extension between the torque wrench and the socket, this will reduce the torque delivered to the bolt.
7.) The grade 9 bolt and special hardened washer have been successfully tested to 600 foot/pounds, in an all - steel application.
