G'day Norm,
That one's a "Scout XL 28" model. They use a cone and plate friction drive setup, like this one:

The cone is the main wear part, and they are available for this model, unlike some of the earlier Cox models.

If the cone engagement surfaces on the plates are grooved, they will need machining. Otherwise, a deglaze is all that's needed. As in :
When installing a new Cox drive cone please insure the drive plate surfaces are in good condition with no grooves. It is
necessary to deglaze the drive plate surface so the new cone will not slip generating excessive heat & damaging the drive cone. As the new
cones can no longer contain asbestos over heating will cause premature failure. A quick way to deglaze the drive plates is to use a 4� disc
sander with medium grit paper. This can also be done quickly at each service to reduce drive failure.
It is only necessary to take the shine off the surface to give the cone a surface to grip to. Any grooves will need to be machined in a lathe
