If you want to fill that crack on the flywheel, lay it flat and use thin-set CA glue to stabilize the crack. If you want to make it look good lay it flat, fill with fine sawdust and fill with Thin CA (the color of the saw dust will darken a bit when you use the glue. . Do it in stages, get as little CA on the surrounding wood as possible. Once the glue dries (pretty quick) sand with a high-grit sand paper and hit it with walnut oil. There are wood dies you could use to match but I think a battle scar would make it look cool.
