That is the flywheel. It has a taper, that is matched to the crank shaft, and is torqued on. You will need a puller to get it off. Harmonic Balancer puller with grade 8 bolts, 1/4-20 about 3" long. Thread them in about 7/16", then start tightening down on the puller bolt. The 5hps usually pop off pretty easy.
The following site should help as well.
