Default Re: Woodruff key No.# size

Basically what you don't want is a loose fitting key, it should be snug and fairly tight fitting, any play here will wear out the slot in the crank or the gear, or whatever the key is supposed to hold in place. You could file one to fit but I would never use one that's too small or that's loose enough to drop right in. It's not the key I'd be worried about messing up here, it's the slot on the crank or clutch shaft you don't want to mess up.
