Yes, the ceramic inserts can be replaced. To replace, remove the guide block or thrust support. Clean the mounting surfaces. A light sanding with 220 grit paper in the groove or on the face of the thrust shaft will provide some “tooth” for the adhesive. Clean the surface with alcohol and let it dry. Use gel super glue to adhere the ceramic to the guide block making sure that the ceramic is flush with the front surface.
