I believe the shaft would be under that plate. The shaft fits into a spline on the flywheel. You will have a double set of splines to pull the shaft through. As you pull the shaft out, it should slide easily. If you come to a sudden stop, it means the second set of splines are not lined up with the first set. Do NOT try to force it out by slam-banging it. You will batter the slines on the shaft. Back the shaft up an eigth of an inch or so and turn it ever so slightly and try to remove it again. Sooner or later you will get both sets of splines lined up and the shaft will slide out with almomst no resistance.
