Yes.  It's a great big bolt that reaches through the center of the fan
extension and threads into the nose of the crankshaft.  You'll likely need a
6-point socket to grab the head (due to the rounded corners).

Impact wrench works a treat, if you have one.  Otherwise you'll need some
way to hold the crank from turning, like maybe a big screwdriver stuck in
the flywheel teeth.
