Started the teardown tonight. Got all the belts and pulleys off except the crank pulley. FSM says the "claw nut" needs to come off 1st then it looks like a gear puller is used to get the pulley off. I thought I'd be lucky with my hub socket but too big. Close, but if I had to guess, I'd say between 30~52mm. Anybody know the size of this nut? Any secrets to getting this pulley off?
