William the shaft is plain. There is a collar at each end located by the the clamp bolts. The inner collar is pinned to the shaft, so it stays with the shaft. Usually the end without the pin has a small taper where it goes into the collar and the other end is just flat. You have a couple of rubber seals, one in each side that is compressed when the clamp bolts are in. It looks like you have it started. Put your clamp bolt back in the outer one and then give the shaft a good hit with a hammer and drift. When the shaft is out you can remove the clamp bolt and knock the collar out from the inside. The inner side of the collars and the faces of the bogie arms have grooves to help hold the seals. I hope thats what you want?
