The lockplate should have U section ring around it, this is to stop oil migrating from axle to hub. It can be withdrawn by screwing in a couple of screws in the tapped holes and easing it out. The eight sided hub box spanner, I forget the size, but mine was bought from a motor factors a few years back, do a search on Ebay, etc for Melco hub spanners.
