I own a 2017 Challenger 750 and had the key way snap at the flywheel. It was removed and cleaned up and then the flywheel was put back on with a new keyway. It snapped a second time so the flywheel and keyway both were replaced. They both seem to fit nice and tight. Put it all back together and it snapped again. I have no idea why it is doing this.
