I started in a separate thread a few weeks ago. As my username entails, I'm new to this stuff so please bear with me if my description of parts isn't perfect.
In short, I broke the extender piece on the inside of the pulley, the piece that hooks to the chain. The pic motobecane3 tries to show the broken pulley. I bought the new pulley, and it's ready to install, but the old pulley doesn't come off? at least not easily. The pic motobecane1 tries to show that I've taken the pedal off, taken that rubber piece off, and loosened the bike chain (not sure if that was even necessary). Am I just not pulling the pulley hard enough, or is there something else that I need to unscrew before the pulley comes off?
Having a lot of fun learning moped repair, as slow as that may be. Thanks in advance for help.
