If you look at the first pic, there is a hub on the right that's approx. 7/8 wide. That section is a smaller diameter than the rest. That is the hub that mounts up on the hub of the flywheel and is held on with the set screw that you can see just above the tape. It actually sets back inside the rim of the flywheel. If you watch the video Jamie posted, you can see it around the one minute mark. That leaves the actual pulley about 3 1/2 in wide. If you look at it close it is a little bigger diameter in the center than the ends. That's called the crown of the pulley and was to help keep the belt aligned and running on the pulley instead of walking off. Most pulleys mount directly to the crank but there isn't enough crank sticking out on the Beeman so they mounted it to the flywheel. The only thing that holds it is the set screw so I'm not sure how much it would pull. Some of the hit and miss engines had the pulley bolted to the flywheel.
