Hi All does anyone know what size the Woodruff key is for the flywheel to slide onto I have somehow misplaced mine for a 33 hp johnson 1968 just wondering what the part size might be as i can just get these at the local hardware store for cents on the $.

Thank you
James

Woodruff keys can be filed down to fit. I do know it is NOT a metric size on the motor. Yes you can get one at a hardware store or an auto parts store

Part number is 0307480 - available at any Johnnyrude dealer. I personally wouldn't use one from a hardware store.

Yep. If that key isn't right, you break the flywheel, the shaft or both. None of which is a particularly pleasant experience. Spend a buck and get the correct key.
