It's a Chevy not a F&*#D the crank pulley is designed to push the crank out when the engine fires, but F*#$D's have a nut that the crank goes on and it doesn't kick out when the engine fires.
Many a broken wrist and arms with that system.
If you hand crank is riding on the bumper when you use it you are missing the support bracket that goes on the center bolt of the bumper to support the hand crank.
