OP, the most likely scenario requiring removal of this item would be failure of the internal mechanism. That happened to me on a multi-cog FW. Otherwise, installing it is best done with a chain-whip, or just install finger-tight and go for a ride.
Yeah, the notches looked too small for the Sun Tour but it was the only similar remover I know about. Hammer and punch time most likely.
One other reason for removal, other than mechanical failure, is if the OP wants to change the gearing.
