G'day Paul,
Yes, the plates slide along their shaft.
I would make sure the shaft is clean and rust free by using a long strip of fine grade wet and dry sand paper, then lubricate it before using your rubber mallet.

Here is some information I have for the older type Cox mower. I've never seen the plates on a Stockman, cant imagine it being too much different.

The clearance from cone to plate is quite small.
