The crankshaft pulley that runs the accessory belt is held with only on bolt. But that is probably the hardest one to remove.
This happens because this bolt is very well tighten and when you’ll try to unscrew it, you’ll just turn the crankshaft.
To stop that, you’ll need to find a way and immobilize the engine so you can unscrew the bolt. If the engine is still mounted in the car, you can put the transmission in Park (or engage first gear if manual) and apply the parking brake. This way, you’ll not be able to spin the crankshaft manually and as a result you’ll unscrew the bolt.
If the engine is not mounted on a vehicle like in the video bellow, you’ll pretty much have to improvise. And the quickest method is to grab a solid metal plate, drill two holes in it and mount it to keep the flywheel attached to the engine block. See how to do it in the video bellow.
