Charlee, you will need to go to a bicycle shop and pick up some Triflow - nothing works like that. That little part you show is still gummed up. The one in the bottom pictures is rarely stuck - that one in the upper picture splits apart after that pin goes out so it needs Triflow to ungum it - it will work so much easier. I think you can also order Triflow here and there on line much cheaper than the bicycle shop.
