I have seen a few of them locked up and it was a shredded coupler that was jammed up in the gears and smoked the belt. It took quite a bit of working it to get it free again. The other was the cage on a meedle bearing and I ended up pressing the bearings out with the rotor by putting the bolts back in without the snout and pressing the bearings with a piece of 1" square stock and a pair of sockets Gen 5 will be different since there's no real access to the bearings although you may be able to drill a hole and tap it 1/4-28 then install Zerk fittings and push it out using hydraulic pressure. The other one was FOD and it ingested a #10 screw (at least that's what it looked like). The Gen 5 the cartridge actually slides almost an inch into the case so they are a lot harder to get apart then a Gen 3. If you take a 3/4" dowel and pass it through to the bearing plate you may be able to knock it out enough to get at the edges. Use a plastic or wood rod to go around the case to get it out then. You will damage several pieces of wood or plastic, but better that than the case. If you try to use Aluminum, Brass or Copper it's too hard. You need something softer than the aluminum Delrin is pretty good for doing this. Just go slow and look after every hit if you get it cocked in there it will be even more difficult to get out.
