Q: How do I remove my shields or seals?
For fixed metal shields you should use an awl. Place the awl on the shield toward the outer race. Punch down lightly until you make a small hole. Then peel the shield back with the awl. Removable metal shields are held in place with a retaining ring. Run a sewing needle along the inside of the outer race to pop out the retainer. Once the retainer is removed the shield should pop out with a light tap. To remove a rubber seal use a pen knife or sharp pointed object. In most cases the rubber cannot be re-used.
