This is first phase. All apart. Did a degrease to clean off the PB Blaster and brass brush with mineral spirits to get the funk off. Only one sprocket had any caked on grease so this was barely used. Now in an overnight soak in evaporust for the rust. Duh. Bearings are toast—some are fully blackened— so have to order more of that size. This one took heat to the 14t ring off. Also took a lot to get the bearing lock ring off. Hardest I have ever worked to get one apart.
