Title: Crank Stud??
Post by: ein bora on September 21, 2012, 03:43:44 pm

I've read some information on using a M14X1.50x33 hardened stud as a replacement to the typical crank stretch bolt.
Does anybody know if this actually works?
I've read lots on the theory that it should work, but nothing if it actually did.

I think it could, but some questions lurk in my mind:

1. Will the stud length interfere with the crank pulley/harmonic balancer/frame horn?
2. Will the corresponding nut be of equal hardness?
3. Will said nut have a seat and/or thick washer under it(THIS IS IMPORTANT; assures even torque force distribution across the face of the crank cog)?
4. What issue will/may be solved going this route?  Helping keep torque on keyway cranks?
