I second person was very helpful because once we removed the hub nut and the 6 screws from the plate on the bottom, inside the basket, it took one of us to hold the basket up a little and the other used a hammer and a long steel pipe, to start tapping on the old splined shaft to remove the basket. This one was stuck on that shaft from a little rust, gunk, etc., but popped off. Everything else was easy from then on. The new gearcase went back in very easy, just make sure you clean your baskets and other parts real good before reassembly
