Woodruff key replacement

[Chainlube]

I stumbled on this thread bc someone told me they thought my woodruff key was sheared based on issues that I've been having. Anyhow, before I go pulling the flywheel off. Would a 144F have the same square key stock?

And if so, do they break or shear as easily as a woodruff key?

It's really hard to break either one. There has to be a catastrophic failure for the key to break. Something like the piston seizing while you're in motion or a coaster brake exploding.

Thank you, that helps alot. I haven't had a failure of that nature.
