After rooting around my tools I found another Suntour tool that I have no idea if it will work.
The search continues.
This is the other Suntour tool I found and I am NOT sure it will be helpful to you.

No, that's the tool for SunTour bottom bracket cartridges.
Unlike Shimano, SunTour, unfortunately, didn't see fit to mark the tool with the part number. 
Found it, in a SunTour dealer catalog: TA230:
The correct tool for the XC hubs is the TA260.
