Hi Grumpy. After a long inspection and a touch of marine Inox I realised there was no locking tab of any sort. The gentlest of taps when set up in this fashion saw the thing come apart very nicely. Just a hammer and a block of wood set up in my saw horses, I wasn't fussed on using a vice for alloy pieces. (the nut on top was obviously removed!!)

The whole assembly came apart nicely revealing the cork pads in a still serviceable condition.

I inspected the square drive that the centre hubs drives on and it was completely free of any burs or wear as was the internals of the drive wheels. Pretty happy with that.

Just a smidge of graphite powder applied to the cork pads as recommended by the service guys at a the local Greenfield agent to stop the small amount of squealing that you sometimes get.

I ended up reinstalling the most of the gear and Grumpy the new chain fits that sprocket very snug. I'm pretty rapt with that as I wasn't fussed on spending another $250. I just need to source a grub screw for the front sprocket and a new drive belt tension pully as the bearing in the old is slightly notchy.
