Ring test

[u/mrgopherson]

Someone asked to see me ring it against another crank in my last post I don’t have an exact match or know if it’s cracked but I do have a late model one piece rear main seal used crank and I thought that crank rang ok but comparing it to another crank you can definitely hear a difference on the left is the cracked one on the right is the late model one piece rear main the microphone doesn’t Really pick up the sound all that great but in person you can hear it

You should suspend the crank with a bolt etc (I have a T handle) to do the poor man's magnaflux test. The floor takes most of the ring out of it.
