What You’ll Need

In order to hand crank a car engine, you’ll need the following items:

-A piece of wire (optional)

Tips for a Successful Hand crank

Hand cranking can be a great way to get your engine running if you don’t have access to an electric cord or battery. Follow these tips for a successful hand crank experience:

1. Position yourself so you have good leverage. Sit or kneel next to the engine with your feet flat on the ground and your hands close to the flywheel.

2. Keep your arms straight, and use a smooth motion. Do not use too much force at once, or you may damage the engine. Start with a slow rotation and gradually increase the speed as you become more comfortable.

3. Be patient – it may take some time for the engine to start. Don’t give up if it doesn’t turn right away – keep trying until it does.
