95 300 TRX front hub part missing?

Picked up a used bike and I think I am missing something. Put new bearing up front and when I go to put it back together it seems something isnt there (explains why the seals are trashed). Is there some sort of a spacer or something before I put the castle nut on? The castle nut it hitting the seal now and I know that isnt right. Anyone know what I am missing? Have a picture of it correctly installed? Thanks
