Scrape off any remaining old felt with a putty knife or razor blade. Remove remaining, hardened adhesive left from the old felt with adhesive remover.
Clean the track where the felt goes with rubbing alcohol. Allow it to dry.
Apply a single bead of adhesive along felt seal track.
Insert one end of the felt into the felt seal track on the drum. Wrap the felt around so that the opposite ends meet and the felt strip fully encircles the drum.
Run your finger along the felt to press it into place. Quickly wipe up any glue that oozes out with a damp rag.
Allow the adhesive to dry for at least two hours.
