If you are able to get behind the inner race it would probably come off. That is why it is better to grab behind the sprocket with a splitter.
It was indeed under the outer race.That makes perfect sense, and I hadn't considered that. Thank you. I've got another larger gear puller, whose legs I can alter a bit to let me get under the gear. Its nice to have this junk crank to experiment with. Tomorrow, I'll work on it and check back in. Thanks all for your suggestions.
