I may be way out in left field here as I haven't had the opportunity to physically see this scenario, but an old machinist taught me this trick to removing blind bearings/bushings in crankshafts (clutch pilot bearings). You first need to find something that will fit into the inner diameter of the bearing to be removed, the tighter the fit the better, but it needs to have enough clearance to move easily in the inner bore of the bearing. Kinda like the fit of the master link in a chain, not a machined fit, but tight enough it doesn't wobble all over the place. This can be a bolt, a piece of allthread, a brass/steel punch or whatever has a pretty snug fit. Next pack the cavity under the bearing with the thickest grease you can get by pushing it through the inner race of the bearing, essientially filling the whole cavity up with grease to the top of the inner race of the bearing to be removed. Then insert the previously selected piece that fit into the inner race of the bearing and force down into the inner race (remove some grease if needed you can add it back later) enough that the race willl guide it when you start to hammer it in. As previously stated you are going to strike the aforementioned piece that fits into the inner race of the bearing with a hammer. You don't need to swing from the backyard or hit it like some redheaded brat from down the road, just a nice sharp,accurate strike and whatever bearing is there will start to move. You will need to add grease every three to four strikes to keep the pressure where you need it but it won't take long and your bearing will be free. This works even if there is a "drain hole" for the oil underneath the bearing, it takes a little longer in this situation due to the leakage through the drain hole, but just keep packing in the grease and beating it with the hammer, you'll get it. Hope this helps.
