That's the problem--it isn't the correct diameter. Hence my wanting to turn them down.

The crank bolt in this particular system has TWO "main functions." If the shoulder surface is even just 1 mm wider than the hole in the crank arm, it will be enough to do what it needs to do. There is very little if any outward force on the crank arm.

I don't think I would ever consider using a crank removal tool--Park or otherwise. Wouldn't want to booger up the BB spindle--which was not designed to have a crank arm puller forced against it.
